Stefan Flores, MD
Emergency-medicine trained optimization physician focused on hormones, metabolic health, and athletic performance
About
Stefan Flores, MD is a Columbia-trained, board-certified emergency physician working as a partnered provider on Marek Health's Guided Optimization platform. He completed emergency medicine residency at Highland Hospital, the UCSF-affiliated county trauma center in Oakland, then practiced for more than a decade across urban, rural, academic, Indian Health Service, and international settings. A former swimmer, basketball player, and rower who still lifts and runs, Flores brings an athlete's frame of reference to hormone, metabolic, recovery, and performance optimization.
What to Know
Signature approach
Flores brings emergency-medicine judgment to telehealth optimization: triage first, then protocol design. In Marek consults, that means separating urgent red flags from optimization targets, reading labs in the context of symptoms and training demands, and building around hormonal balance, metabolic function, recovery, and athletic performance.
What sets them apart
- Broad emergency-medicine calibration. Columbia MD, Highland/UCSF residency, and experience across urban trauma, rural ERs, academic centers, Indian Health Service, and international settings.
- Performance-facing clinical lens. His background as a swimmer, basketball player, rower, lifter, and runner gives him a practical reference point for recovery and training goals.
- Active clinical range. Flores also runs Allostat Health in Scottsdale and has an A4M Longevity Medicine Fellowship in progress.
