Dr. Larson

David Larson, MD, or as his patients prefer to call him, Dr. Dave, is an integrative medicine physician who’s passionate about helping patients create personal breakthroughs in their health and well-being. At his practice, SourceMD: Integrated Wellness Solutions in Encinitas, California, Dr. Dave treats the full range of mental and physical problems, serving as each patient’s partner and health coach.

Dr. Dave’s warmth and whole-person approach to health care make it easy for patients to work with him as they develop an individualized treatment that focuses on lifestyle interventions to prevent illness and disease.

A native San Diegan, Dr. Dave graduated from Brown University, spent a year in Spain as a teacher and researcher on a Fulbright Fellowship, and then worked in rural India on a grassroots public health program. Following his calling to medicine, he attended the University of Southern California, Keck School of Medicine, in Los Angeles, graduating with the highest distinction and earning the Alpha Omega Alpha merit scholarship.

Dr. Dave completed his residency training in family medicine and psychiatry at the University of California San Diego, then finished a fellowship in integrative and holistic medicine through the University of Arizona in Tucson, Arizona. He’s double board-certified by the American Academy of Family Physicians and the American Board of Psychiatry and Neurology.

Since the beginning of his health care journey, Dr. Dave has studied and practiced functional medicine which uses a systems biology approach to address the root causes of disease, restoring the body to its natural state of vitality. As an integrative psychiatrist and psychotherapist, he has extensive experience helping patients with stress management, work-life balance, relationship difficulties, and the full range of mental health disorders. He focuses on ruling out medical causes of psychiatric symptoms while also providing a range of therapies, including cognitive behavioral therapy and neurolinguistic programming.

Dr. Dave is an accomplished author, teacher, and speaker, who’s fluent in Spanish. He regularly teaches medical students and conducts personal growth and leadership seminars, as well as couples workshops. He even has a TED talk to his credit.

As a surfer, yogi, runner, health nut, and life-long learner, Dr. Dave practices what he preaches. Devoted to his family, he resides in Leucadia with his beloved wife, Janna, their 3 sons, and their family of rescue animals.
