Clinical-Grade Diagnostic Technology

Every treatment protocol at Stahl Medical starts with measurement. We use two best-in-class diagnostic tools to ensure your plan is built on data, not assumptions.

KORR CardioCoach — Metabolic & VO2 Max Testing

Measures your resting metabolic rate through breath analysis - determining precisely how your body burns fuel at rest. We also use the CardioCoach for VO2 Max testing, which quantifies your cardiorespiratory fitness and aerobic capacity: one of the strongest predictors of long-term health and longevity in the clinical literature. Standard calculators estimate. KORR measures. The result is a protocol built around your actual physiology, not a population average.

VO2 Max measure your cardiorespiratory fitness - currently the strongest independent predictor of all-cause mortality in the clinical literature.

SECA Medical Body Composition - Beyond BMI

SECA's clinical-grade analysis distinguishes muscle mass, fat mass, and visceral fat with precision that a standard scale or BMI calculation cannot provide. We use it at baseline and at follow-up to track real physiological change — not just weight.

We measure before we treat — because personalized care requires personalized data.

Comprehensive, physician-led care tailored to you.

Natural-looking aesthetic treatments and advanced skin technology designed to refine tone, texture, and confidence.

Next week is my third IPL treatment. Kim has been great to work with as she is confident, knowledgeable with a calming presence. I am happy with my results and glad I took advantage of the special offered prior to end of 2025.

Had a facial last week at Stahl Medical and I was blown away with the experience. Kim described every step along the way with an explanation of every product she applied to my face. At the end, I honestly saw a huge difference in my skin, from dull and tired looking skin to actually glowing. Wow! I've already booked my next facial!
