SourceMD: Integrated Wellness Solutions in Encinitas is a concierge medicine practice on Saxony Road led by Dr. David Larson, a physician double-board certified in family medicine and integrative medicine who limits enrollment to 150 patients. The practice's Comprehensive Wellness Assessment functions as an executive physical program combining genetic analysis, functional lab panels, microbiome stool studies, and lifestyle evaluation, a root-cause diagnostic approach that complements the musculoskeletal and rehabilitation care at Gaspar Doctors of Physical Therapy in the Encinitas medical corridor. Functional medicine consultations map the interplay between genetics, hormonal markers, gut-health indices, and stress physiology to develop individualized diet, supplement, and training protocols targeting chronic disease reversal. The clinic's integrative psychiatry services address mental health through the same whole-systems lens, a combined physical-and-psychiatric model that aligns with the naturopathic treatment philosophy at Gaia Naturopathic and Acupuncture Clinic nearby. Concierge-tier patients receive same-day access, extended consultations, and ongoing health-coaching built around comprehensive stool analysis, DUTCH hormone panels, and organic acids testing for metabolic pathway mapping.
