Board-certified Family Medicine and Obesity Medicine physician and founder of Medley Health, a virtual Direct Primary Care practice focused on longevity and metabolic health. My approach goes beyond standard care — I evaluate the hormonal, metabolic, and inflammatory root causes that most conventional workups miss. Every supplement in my dispensary is evidence-informed and chosen for quality, bioavailability, and clinical relevance. I recommend only what I would take myself or prescribe to my own family.
