Casey Means, M.D. Professional History and Bio

Summary

Dr. Casey Means is an American medical doctor, entrepreneur, #1 New York Times best-selling author, and health educator. She graduated with honors from Stanford University in 2009 and earned her medical degree from Stanford University School of Medicine in 2014, before completing four years of surgical training in the field of Otolaryngology-Head and Neck Surgery. 

She has held full-time biomedical research positions at the National Institutes of Health, Stanford University School of Medicine, New York University, and Oregon Health and Science University, and served as a faculty lecturer at Stanford University. Over the past 15 years she has published scientific peer-reviewed papers in major medical journals, along with numerous health policy op-eds in leading outlets. She is a leader in the field of Medical Humanities – the intersection of art and medicine – serving as the founding Associate Editor of the Medical Humanities section of the International Journal of Disease Reversal and Prevention. She has published short stories, poems, book reviews, and reflective essays on the practice and art of medicine.

Dr. Casey Means

After completing four years of surgical residency in Otolaryngology–Head and Neck surgery, Dr. Means resigned from her residency in late 2018 to focus on reforming the “sick care” paradigm in American healthcare. Her work centers on introducing a systems-thinking perspective to clinical medicine, highlighting the interconnected physiological root causes of many of the most common Western chronic diseases. After being awarded a full medical license in Oregon in 2018, she opened a private practice in Oregon in early 2019 focusing on holistic health and functional medicine, called Means Health.

In an aim to scale functional medicine principles and nutritional awareness to a wider population, she co-founded the health company Levels in late 2019, which empowers individuals to monitor and understand their key metabolic biomarkers, aiming to increase awareness of factors that contribute to the most common and preventable diseases in the United States. The company’s stated mission is to “reverse the metabolic disease epidemic,” and since 2022 has undertaken an Institutional Review Board-approved research study of over 10,000 participants to characterize glucose patterns in a non-diabetic population to better understand the transition from healthy glucose levels to overt metabolic dysfunction. 

Dr. Means is the co-author of Good Energy: The Surprising Connection Between Metabolism and Limitless Health, published in May 2024 by Penguin Random House. The book became an instant #1 New York Times bestseller and remained on the bestseller list for 41 weeks. Her podcast appearance with Tucker Carlson talking about themes of Good Energy became the #1 most shared podcast of 2024, according to Variety Magazine. On September 23, 2024, she spoke along with Dr. Marty Makary and Robert F. Kennedy. Jr., at a Senate roundtable on the chronic disease crisis in America, hosted by Senator Ron Johnson.

On May 7, 2025, President Donald Trump nominated Dr. Means to serve as Surgeon General of the United States.

Early life and education

Casey Means was born on September 24, 1987, in Washington, D.C., to Grady and Gayle Means. Her father served as an assistant to Vice President Nelson Rockefeller, worked on health and human welfare issues at the Department of Health, Education, and Welfare, and later became a managing partner at PricewaterhouseCoopers. Her mother, Gayle, passed away from stage 4 pancreatic cancer in January 2021.

High school and college

Means attended Holy Trinity School in Georgetown, Washington, D.C., before graduating from the Madeira School in McLean, Virginia, in 2005. She was honored with the Young Alumna Achievement Award by the Madeira School in 2020 for embodying “courage, vision, and self-confidence.” In high school, she was a competitive athlete, serving as captain of both the varsity basketball and volleyball teams, playing AAU basketball, and serving as president of Model UN.

During her junior year at The Madeira School, she worked one day per week in the office of Senator Richard Lugar (R-IN), and in her senior year, she spent a year in the lab of Dr. McDonald Horne at the Department of Clinical Hematology, National Institutes of Health (NIH) in Bethesda, Maryland, researching Sickle Cell Anemia. She returned to Horne’s lab after her freshman year at Stanford for the 2006 NIH Summer Internship Program, culminating in a presentation titled Determining the Effect of Cellular Microparticles on Thrombin Generation in Sickle Cell Disease Patients.

Means attended Stanford University, graduating with honors in 2009 with a bachelor’s degree in Human Biology. At Stanford, she was elected as president of her class.

Late 2004, speaking at Model UN in Washington DC, as President of Model UN at The Madeira School. Age 17.

Working at the National Institutes of Health in the laboratory of Dr. McDonald Horne.

At Stanford, she conducted honors research in the lab of Anthony Oro, M.D., PhD, on cellular signaling pathways involved in hair follicle and basal cell carcinoma development. Her honors thesis, Determining the Molecular Mechanisms Controlling the Early Telogen to Anagen Transition in Proteasome and Inhibitor-Treated Mice, led to a publication in Stem Cells titled Partial Proteasome Inhibitors Induce Hair Follicle Growth by Stabilizing β-Catenin. She was selected as the recipient of Stanford’s Excellence in Human Biology Honors Research Award in 2009, and her work was awarded a Stanford Undergraduate Research Major Grant.

Alongside her scientific studies, Means immersed herself in the humanities and poetry, completing courses at Stanford including Modern British Poetry, Ecology Through Poetry, Courtly Love in Classical Persian Poetry, Novels and Theater of Illness, Medical Anthropology, Chinese Religious Classics, and Writing and Rhetoric, amongst other humanities coursework. This humanities foundation later informed her leadership in medical humanities, exploring the intersection of art, science, and clinical practice.

Her college years also included international volunteer work, participating in preventative ophthalmological care and cataract surgeries with Unite for Sight in Patna, India, and volunteer work at Stanford’s Arbor Free Clinic. She trained in wilderness medicine and led wilderness backpacking trips for Stanford students in the Sierra Nevada mountains and throughout California through the Stanford Pre-Orientation Trip Program (SPOT) and the Stanford Redwood Club, respectively. She was a teaching assistant for Russ Altman, MD, PhD’s class “Genomics: A Technical and Cultural Revolution,” and through this course was introduced to 23andMe’s co-founder, Linda Avey. She subsequently interned for 23andMe in 2007 for a summer in college, supporting the company’s genetics education curriculum.

Post-college 

Immediately after graduating from Stanford, Means moved to New York City to pursue biomedical research at the New York University (NYU) Skirball Institute for Biomolecular Medicine, working full-time as a research technician in the lab of Dr. Jesus Torres-Vasquez. This work culminated in the publication of a paper in Developmental Cell titled Semaphorin-PlexinD1 Signaling Limits Angiogenic Potential via the VEGF Decoy Receptor sFlt1.

Medical school

While working at NYU Skirball Institute, she applied to medical school and ultimately returned to Stanford, matriculating at the Stanford University School of Medicine in 2010. According to a statement from the school, she was recognized as an “outstanding student” and a “distinguished scholar” during her time in medical school. She was awarded Honors in “Patient Care” and “Professionalism and Interpersonal Communication” in every required clinical clerkship at Stanford Medical School. 

While at Stanford Medical School, she developed a research project with the Department of Medical Education under the leadership of Dean Clarence Braddock, M.D., advocating for less sedentary learning environments, including the introduction of standing desks in classrooms. She received a MedScholars Research Award to pursue this work, presenting her findings at the Stanford Medical Student Research Symposium in 2013 and delivering a talk during the Stanford Medical Education Seminar Series in 2012.

Career

Surgical residency 

Upon graduating from Stanford Medical School in 2014, Casey Means began her surgical residency at Oregon Health & Science University (OHSU) in a five-year otolaryngology–head and neck surgery program, which was her top-ranked residency program. In 2015, she completed her intern year in general surgery before formally entering the Head and Neck Surgery program.

In addition, Means conducted biomedical research in the Department of Otolaryngology under Robson Capasso, M.D., focusing on the long-term surgical outcomes of radiofrequency ablation to the inferior turbinates. This work resulted in two publications: Inferior Turbinate Classification System, Grades 1 to 4: Development and Validation Study in The Laryngoscope, and Long-Term Outcomes of Radiofrequency Ablation of the Inferior Turbinates in the Indian Journal of Otolaryngology Head and Neck Surgery, for which she was the first author.

While in medical school, Means served as a teaching assistant for Medical Creative Writing under Audrey Schafer, M.D., and Wilderness Medicine under Grant Lipman, M.D.

In 2013, she was inducted in the Gold Humanism Honor Society, an honor given to individuals recognized for practicing patient-centered medical care while modeling integrity, excellence, compassion, optimism, respect, and empathy. According to Dean at Stanford University School of Medicine, she was a unanimous choice for this distinction.

Alongside this work in medical school, she published extensively. She served as humanities editor for Stanford H&P: The Stanford Medical Student Journal, where she published several poems on clinical medicine. Her essays and poetry were also accepted into national and professional publications, including “My First Patient” in Intima: A Journal of Narrative Medicine; review of “100,000 Hearts, a Surgeon’s Memoir” in Pharos, the journal of the Alpha Omega Alpha Honor Medical Society; and the poem “C-Section” in the American Journal of Obstetrics and Gynecology in 2014.

Additionally, in 2011, she helped organize Stanford’s Medicine and the Muse Medical Humanities Symposium, helping to bring concert pianist and Cornell psychiatrist Dr. Richard Kogan to Stanford to discuss “The Mind and Music of Beethoven.”

Her passion for wilderness medicine continued during medical school, including leading a SWEAT (Stanford Wilderness Education Active Orientation) trip for incoming medical students in the Sierras. In 2010 and 2011, she completed two 30-day wilderness training courses through the National Outdoor Leadership School, one in the Wind River Range of Wyoming and another in Talkeetna, Alaska. These trips involved gaining skills in wilderness medicine, backcountry off-trail navigation, leadership, and wilderness survival decisionmaking. Through college and to the present, Means led trips, backpacked, and/or hiked on trips in Alaska, the Pacific Northwest, the Sierra Nevada mountains and Yosemite, Kings Canyon, the Bay Area, Wyoming (Wind River Wilderness), the California Coast & Channel Islands, South America (Patagonia & Peru), the Southwest, Death Valley, and the Italian Dolomites.

During her residency, Means completed a six-month research fellowship in the lab of Dr. Lisa Coussens, focusing on the tumor–immune microenvironment of thyroid cancer. This work resulted in her first-author publication in Head & Neck titled Tumor Immune Microenvironment Characteristics of Papillary Thyroid Carcinoma Are Associated with Histopathological Aggressiveness and BRAF Mutation Status. Her research advisor in the lab, Takahiro Tsujikawa, M.D., Ph.D., remarked that he had “never met someone as brilliant and compassionate” as Means.

Means’ scholarly concentration in medical school was "Biomedical Ethics and Medical Humanities,” under the mentor Audrey Shafer, M.D. For her final project, she produced a collection of 17 essays, reflections, and poems examining the nature of medical education, titled Rotating: Reflections on the Dizzying Adventures of a Clinical Medical Student. In the introduction, she wrote:

“A career in medicine allows one to interface daily with all permutations of suffering, joy, family dynamics, delusion, religious beliefs, and socioeconomic statuses. Life within the wards is prosaic, poetic, and often seemingly fictional: as one professor rightly said early in my training, medicine is the front row seat to life.”

In recognition of her biomedical research, she was awarded the first-place award for Excellence in Basic Science from Dr. Mark Wax and Dr. Paul Flint, chairman and program director of the residency program, in June 2017.

During her residency, Means also published Pediatric primary Sjögren syndrome presenting with bilateral ranulas: A case report and systematic review of the literature, for which she was the first author.

As her residency progressed, however, Means grew increasingly disillusioned with the reactive “sick care” model she encountered in her clinical practice. This shift in perspective led her to take time away from her surgical training to explore the intersection of holistic health and surgery. Extensive documents and emails from this period show a prolonged effort to merge her surgical work with a holistic and “root cause” approach, securing meetings with the Chief Wellness Officer at Cleveland Clinic, faculty from National University of Natural Medicine, the Casey Health Institute (which has developed an integrated approach to healthcare blending complementary and conventional therapies), and many other experts for guidance on opportunities to design and foster a more proactive and holistic practice within the surgical ecosystem. Ultimately, she felt so disillusioned with the practice and incentives of surgical care that she chose to resign and work on reform from outside the “system.”

She summarizes this in her book Good Energy

“I deeply respect doctors, but I want to be very clear on something: at every hospital in the United States, many doctors are doing the wrong things, pushing pills and interventions when an ultra-aggressive stance on diet and behavior would do far more for the patient in front of them. Suicide and burnout rates are astronomical in health care, with approximately four hundred doctors per year killing themselves. (That’s equivalent to about four medical school graduating classes just dropping dead every year by their own hand.) Doctors have twice the rate of suicide as the general population. Based on my own experience as a young surgeon, I think a contributor to this phenomenon is an insidious spiritual crisis about the efficacy of our work and a sense of being trapped in a system that is not working but seems too big to change or escape.” 

Two weeks after resigning from residency, Means participated in a business retreat for physicians with Dr. Pamela Wible focused on designing an “Ideal Medical Practice,” beginning on October 14th, 2018. In December 2018, she obtained her unrestricted medical license with the state of Oregon, and incorporated her medical practice, “Means Health,” in January 2019, to implement a holistic and functional medicine approach in clinical practice. She began training with the Institute for Functional Medicine (IFM), completing the foundational “Applying Functional Medicine in Clinical Practice” on March 8th, 2019 and completing further coursework with IFM, and started giving talks on Functional Medicine and “food as medicine” in Portland, Oregon. 

Levels

As Means began seeing more patients in her private practice in Portland, Oregon, she started thinking about ways to scale functional medicine principles and accessibility to a wider population. This led her to conceptualize a company that would use existing lab information from routine blood work as an educational biofeedback tool to empower patients to understand their health. While circulating this concept, called “Labracadabra,” within her close network in July 2019, she was introduced to the co-founders of an emerging startup called Levels working on a overlapping concept. After getting to know the team, she began consulting for the company, helping develop early strategy and content on metabolic health—an area largely underserved in the online content ecosystem at the time. After several months of both consulting with Levels while also maintaining her private practice, she joined Levels full-time as a co-founder in March 2020, gradually phasing out her medical practice to focus on the company’s rapid growth.

At Levels, she initiated the company’s content arm—including the blog Metabolic Insights—and began recruiting the medical advisory board while supporting initial academic research collaborations between the company and academic advisors. The process of building this content operation is discussed in a two-part series on the Levels podcast A Whole New Level (“Building the Levels Content Engine, Part 1” and “Building the Levels Content Engine, Part 2”). Advisors to Levels have included preeminent metabolic researchers and clinicians including:

  • Gerald I. Shulman, M.D., Ph.D., MACP, MACE, FRCP – The George R. Cowgill Professor of Medicine and Professor of Cellular and Molecular Physiology at Yale School of Medicine, internationally recognized for research on insulin resistance and type 2 diabetes.

  • Robert H. Lustig, M.D., M.S.L. – Professor Emeritus of Pediatrics in the Division of Endocrinology at the University of California, San Francisco; neuroendocrinologist specializing in childhood obesity and metabolic health; and Director Emeritus of UCSF’s WATCH Program.

  • Sara Szal, M.D. – Harvard-trained physician, Director of the Precision Medicine Program at the Marcus Institute of Integrative Health, Clinical Assistant Professor at Thomas Jefferson University, and four-time New York Times bestselling author in functional and integrative medicine.

  • David A. Sinclair, Ph.D., A.O. – Professor of Genetics at Harvard Medical School, co-director of the Paul F. Glenn Center for Biology of Aging Research, and internationally recognized researcher on aging and epigenetics.

  • Ben Bikman, Ph.D. – Associate Professor of Physiology and Developmental Biology at Brigham Young University, researching insulin resistance, metabolic disorders, and mitochondrial function.

  • Dominic D’Agostino, Ph.D. – Tenured Associate Professor in the Department of Molecular Pharmacology and Physiology at the University of South Florida Morsani College of Medicine and Research Scientist at the Institute for Human and Machine Cognition, focusing on ketogenic metabolic therapies.

  • Mark Hyman, M.D. – Founder and Director of The UltraWellness Center, Senior Advisor for the Cleveland Clinic Center for Functional Medicine, and internationally recognized leader in functional medicine and nutrition.

  • David Perlmutter, M.D., FACN, ABIHM – Board-Certified Neurologist, Fellow of the American College of Nutrition, member of its Board of Directors, and multiple-time New York Times bestselling author specializing in brain health and the gut–microbiome connection.

Many of these advisors also conducted academic-affiliated research with the company to better understand the transition from health to disease in metabolic syndrome. The company was founded on the principle that since most type 2 diabetes and pre-diabetes cases are preventable, it is unacceptable that these conditions are skyrocketing, and the public health response is failing, as evidenced by rates going up every year. Given that accessible tools already exist to understand blood sugar levels before they reach clinical thresholds, like direct to consumer lab testing and continuous glucose monitors, Levels saw an opportunity to empower people with personal health data to track the trajectory of their metabolic biomarkers and the environmental factors influencing blood sugar well before a clinical diagnosis, and in doing so shift the greater healthcare ecosystem towards a proactive approach to metabolic diseases rather than reaction.

Good Energy

In August 2021, after gaining increasing visibility as a public health educator on podcasts, she was approached by literary agents to represent her in writing a book. With her decade-plus of work and writing in the field of Medical Humanities, writing a book had been a long-term dream. In 2021, in the wake of her mother's passing, she began the process, synthesizing her findings from clinical experience, research, entrepreneurial work, and her study of systems and network biology, holistic health, and patient empowerment. In July 2022, she partnered with Penguin Random House, with a publication date set for May 14, 2024.

Between 2022 and 2023, she moved to Bend, Oregon, to write the book, taking time off from her work at Levels to focus on the project. She resigned from Levels in the winter of 2023 and focused on book promotion between December 2023 and May 2024. The book was formally announced in The Free Press in January 2024, and it hit the rank of number-one bestselling title on Amazon before publication.

After its launch on May 14, 2024, the book became an instant number-one New York Times bestseller and remained on the list for over 41 weeks. 

On August 17, 2024, the podcast episode in which she discussed the themes of Good Energy aired on The Tucker Carlson Show and became the most-shared podcast of 2024, according to Variety magazine. This episode prompted the 2024 Senate roundtable on nutrition and chronic disease hosted by Senator Ron Johnson, who cited it as the “catalyst” for the event, in which Means spoke. Her remarks from the Roundtable can be read here.

In November 2020, Levels raised a $12 million seed round led by Andreessen Horowitz, followed by a $38 million series A in 2022, and a $10 million extension in 2024, making Means part of the just 13% of venture capital funding that goes to startups with women on the founding team.

Through her work at Levels and the company’s mission to spread awareness about metabolic disease, Means began appearing on numerous podcasts, beginning in 2019, to discuss blood sugar dysregulation, metabolic dysfunction, and the modifiable aspects of behavior, lifestyle, and environment that impact metabolic health. The first podcast, hosted by Dr. Laurie Marbas and aired on June 14th, 2019, was called “Having Courage to Follow your Purpose.” Over the next five years, she appeared on more than 200 podcasts, becoming an increasingly prominent voice in health education.

In September 2021, she was invited by Kara Swisher at The New York Times to be a panelist at the Code Conference in Los Angeles, an event that also featured speakers such as Elon Musk, Marc Benioff, Satya Nadella, and Gary Gensler. During this period, she was also featured in The New York Times, The New Yorker, The Wall Street Journal, Women’s Health, Men’s Health, and numerous other outlets. On March 24th, 2024, Dr. Means was invited by Professor Joseph Fuller to be the guest protagonist at Harvard Business School for the case discussion based on Levels, which she is prominently featured in: Levels, the Remote, Asynchronous, Deep Work Management System.

Soon after, Means appeared on The Joe Rogan Experience, airing October 8th, 2024, where she discussed the role of metabolic dysfunction as a central driver of many modern chronic illnesses, including obesity, Alzheimer’s disease, infertility, and cardiovascular conditions. She emphasized how factors such as processed foods, environmental exposures like pesticides, and modern lifestyle patterns contribute to widespread metabolic impairment. Means was critical of the U.S. healthcare system’s focus on pharmaceutical treatments for symptoms rather than addressing root causes, noting that systemic incentives often prioritize volume of care over patient outcomes. She also underscored the connection between human health and the natural world, arguing that “our human health is simply a reflection of the destroyed ecosystem of our globe,” and that treating the body as a miraculous entity and connected to the environment and natural world is essential for long-term well-being, and emphasized the spiritual dimensions of health in addition to its biologically and environmentally-influenced aspects. 

On March 13, 2024, The Texas Heart Institute (THI) at Baylor University invited Means to visit the Institute to discuss metabolic health with its CEO, Dr. Joseph G. Rogers, and Assistant Medical Director, Dr. Stephanie Coulter. This culminated in a video series produced by the THI highlighting Means’ insights from Good Energy, as well as written content shared on the THI website featuring Means’s philosophy on metabolically healthy food.

In January 2024, Means started the “Good Energy Newsletter,” a weekly set of essays on health, food, policy, spirituality, and philosophy, which grew to 199,000 subscribers with a 70% open rate by February, 2025, and was mentioned in the New York Times and many other publications. 

Surgeon General nomination and controversies 

On May 7th, 2025, President Donald Trump announced that he would nominate Means for Surgeon General at the recommendation of Robert F. Kennedy, Jr.

Her pick was immediately criticized by mainstream media outlets, which labeled her a “wellness influencer,” “pseudoscientific,” and “unqualified,” with the New York Times ultimately issuing a correction on May 11, 2025 for falsely propagating that she was an unlicensed doctor, stating “An earlier version of this article misstated the status of the medical license held by Casey Means, the president’s pick for surgeon general.” Responses to this widespread backlash from legacy media included articles criticizing mainstream media for their biased framing of her work, including “Rise of the "Woo-Woo" Woman: The Witch Hunt for Dr. Casey Means” by Lauren Lee, which stated that “the backlash against Trump’s pick for Surgeon General isn’t about science — it’s about a country terrified to confront its own spiritual collapse.”

Means is considered controversial because her work challenges the economic and cultural foundations of U.S. healthcare, agriculture, and food systems. She criticizes “sick care” medicine for profiting from disease management, calls for reform of the Farm Bill, pharmaceutical incentives, food culture, and industrial agriculture, and integrates spirituality, ecology, and patient empowerment into her philosophy—departures from conventional frameworks that have led some outlets to label her “unscientific.” Legacy media critics often dismiss her credibility because her message exposes institutional failures and calls for disruption, and her career trajectory has included periods without direct one-to-one patient care while pursuing work in preventative health that has reached tens of millions. Some critics cite her work as an entrepreneur and health-technology co-founder as incompatible with public health leadership, overlooking Levels’ large-scale research collaborations with academic institutions and the complex management and operational skills required to build a high-growth company. Others argue she oversimplifies chronic disease and places too much responsibility on individuals, failing to recognize that her approach explicitly advocates for both bottom-up empowerment—equipping individuals with the knowledge to understand their own bodies—and top-down systemic reform that makes healthy choices affordable, accessible, and the cultural default. Finally, her stances on medications and emerging therapies such as vaccines, oral contraceptives, and psychedelic therapies have drawn intense scrutiny, though her consistent position on each of these therapies has strongly emphasized informed consent, medical freedom, and ending corporate liability shields and conflicts of interests that often distort research findings and prioritize profit over patient well-being. She is falsely accused of not having a medical license, despite having held a license for over 11 years, including an “MD post-graduate license” since 6/26/2014 and a full MD license since 12/07/2018, which is still current and unexpired. The status of the license was voluntarily placed on "inactive” status on 1/1/2024, as she was not actively seeing patients. She has been criticized for being an “influencer” and widely labeled as such as a response to having sponsors which support her newsletter and for whom she has shared marketing links. Additionally, online critics have argued that she appeared in the national health discourse seemingly “overnight,” ignoring a consistent history of writing and messaging on holistic and preventative health topics across media, podcasts, and writing over two decades.
