Internal Medicine Depth. Longevity Strategy.One Physician Who Holds Both.

Longevity medicine without clinical rigor becomes superficial. Internal medicine without early evaluation and long-term strategy becomes reactive.

Alpenglow combines the diagnostic depth of internal medicine with a proactive, personalized plan designed for health and performance over decades.

The gap in today's healthcare

Rushed and reactive on one side. Shallow on the other.

Most primary care is rushed and reactive: fifteen-minute visits, a problem list, a referral. Most optimization clinics are the opposite: long menus of tests and supplements with little clinical depth behind them.

Active adults in a mountain community feel this most acutely, coordinating care across providers, systems, and states, with no single physician who holds the whole picture.

Alpenglow Health exists to close that gap.

Internal Medicine · The George Washington University School of Medicine · Residency, Icahn School of Medicine at Mount Sinai

I trained at The George Washington University School of Medicine and completed my residency at the Icahn School of Medicine at Mount Sinai in New York City. I then spent years in hospital medicine, where complexity is routine and diagnostic precision is essential.

I built Alpenglow after years of watching preventable disease arrive in the hospital fully formed. I wanted to intervene earlier, with more time, more data, and a long-term plan.

I've lived in Jackson for over a decade. I ski, trail run, hike, and bike these mountains, and I practice medicine for people who intend to keep doing the same.
