About TMD Health

A physician-led practice focused on longevity, prevention, performance, and measurable health optimization.

The current healthcare system is primarily designed to react to disease after it develops.

TMD Health was created around a different question:

How do we identify physiologic decline earlier, intervene intelligently, and help people maintain strength, resilience, performance, and independence over time?

From Reactive Medicine to Health Creation

During my years practicing Emergency Medicine, I cared for thousands of patients whose conditions had progressed to advanced disease and critical illness.

Over time, I became increasingly interested in a different challenge:

How do we identify dysfunction earlier—before it becomes irreversible?

That question led to the development of TMD Health: a physician-led practice focused on prevention, longevity, performance, and objective physiologic assessment.

The goal is not simply to extend lifespan, but to preserve function, resilience, cognition, strength, and independence for as long as possible.

This requires a more proactive and individualized approach than traditional episodic medicine alone.

Philosophy

TMD Health combines:

  • evidence-based medicine

  • exercise physiology

  • cardiometabolic health

  • longitudinal assessment

  • individualized implementation strategies

The practice emphasizes:

  • objective measurement

  • thoughtful interpretation

  • sustainable implementation

  • avoidance of unnecessary complexity

The goal is not to pursue every possible intervention.

The goal is to identify the highest-leverage strategies for each individual based on physiology, goals, risk profile, and stage of life.

  • Founder, TMD Health

    Dr. Trent Tennyson is a board-certified emergency medicine physician with a background in high-acuity, frontline care and a specialized focus on prevention, performance, and longevity medicine.

    He earned his degree in Biology from the University of Colorado Boulder, followed by a Master’s in Genetics from University of Connecticut, and his medical degree from Albany Medical College. He completed residency training in Emergency Medicine at UPMC, where he served as a field physician with Pittsburgh EMS, a flight physician with Stat MedEvac, and supported tactical operations with the Pittsburgh SWAT team.

    Following residency, Dr. Tennyson practiced in diverse clinical environments including UPMC in Pittsburgh, Henry Ford Health, and Hackensack Meridian Health.

    Through this experience, he recognized a critical gap in modern medicine: a system optimized to treat disease, but not to prevent it. He founded TMD Health to address this gap—focusing on early detection, risk reduction, and measurable performance optimization.

    His clinical approach integrates advanced diagnostics with individualized, data-driven protocols to improve metabolic health, cardiovascular fitness, body composition, and long-term healthspan.

    Areas of expertise include:

    • Cardiopulmonary exercise testing (VO₂ max, metabolic efficiency, threshold analysis)

    • Lifestyle and longevity medicine

    • Sports physiology and performance optimization

    • Nutrition and body composition strategies

    • Weight loss and metabolic health

    • Strength and endurance programming integration

TMD Health is designed around:

  • direct physician access

  • longer-form conversations

  • individualized strategy

  • longitudinal guidance

  • objective physiologic assessment

Recommendations are tailored based on:

  • goals

  • physiology

  • recovery capacity

  • training background

  • lifestyle constraints

  • medical context

This allows care to become more proactive, precise, and personalized.
