About

Cindy Tsai, MD is a Lifeforce Longevity Clinician and one of the active physicians spotlighted on the platform. She is double board-certified by the American Board of Internal Medicine and the American Board of Integrative Medicine, with a pre-med foundation at Johns Hopkins, an MD from Geisel School of Medicine at Dartmouth, and internal medicine residency at California Pacific Medical Center in San Francisco. Her broader work includes the TEDx talk Body Intelligence, the book So Much Better, mindfulness teaching, and women's preventive health education.

What to Know

Signature approach

Tsai pairs evidence-based internal medicine with mind-body practice. She reads labs and symptoms against longevity-range targets while treating chronic stress, sleep, and nervous-system regulation as first-class inputs. Her clinical frame is especially relevant for high-achieving adults whose labs may look normal while energy, sleep, or stress resilience are still off.

What sets them apart

  • Double board-certified (ABIM + ABOIM). Formal Integrative Medicine boards on top of standard Internal Medicine; a stronger credential stack than most telehealth longevity clinicians carry.
  • Multi-state telehealth footprint. Active medical licenses across 20+ states support full-time telehealth practice at national scale.
  • Mind-body fluency. TEDx speaker, author, mindfulness teacher, and founder of Yes & More, giving her a practical language for stress, sleep, and nervous-system regulation alongside biomarker optimization.

Before You Book

  • Care focus. Integrative internal medicine, stress physiology, sleep, and women's preventive health.
  • Access. Book through Lifeforce membership; public pages do not offer direct clinician selection outside the platform.
  • Care focus. Telehealth consults and lab interpretation, not procedural medicine.
