The approach
"There is a scientifically proven, safe, natural way to rewire your body's baseline stress response and optimize your health and performance."Dr. Leah Lagos

Peak performance isn't just mental training. It's aligning mind and body so your natural abilities unfold consistently. Dr. Lagos integrates HRV biofeedback, breath training, mindfulness and performance skills into one system — trained with you, in person, and tailored to your specific demands.

  • Reduce stress and anxiety
  • Turn off the busy brain
  • Enhance focus and attention
  • Improve sleep quality and duration
  • Recover faster from stressors
  • Navigate challenges with precision
  • Increase physical stamina and mental endurance
  • Achieve mental clarity
The 10-week HRV biofeedback protocol

Ten weeks of HRV biofeedback. A lifetime skill.

Heart rate variability biofeedback lets you gain control over your body's response to stress using signals from your own body. The benefits are felt within weeks — and once learned, cannot be unlearned. Sessions run 45–50 minutes and are entirely non-invasive.

Measured outcomes

Ten weeks. Results you can measure.

The same protocol taught in this office appears in Dr. Lagos's peer-reviewed research. A sample of what ten weeks of training has produced under study conditions:

Speaking & press
Remote work

Train on Park Avenue, NYC, or from anywhere.

The protocol does not require a Park Avenue address. Remote clients follow the identical 10-week architecture over video — same biofeedback training, same objective HRV tracking, same one-to-one format.

Most clients outside New York begin with a single in-person consultation, then continue remotely; many complete the entire protocol from London, Riyadh, Los Angeles, and wherever the season takes them.

In their words

Described as life-changing.

"I can summon the breathing at times of stress — if I feel myself breathing shallowly or getting anxious about a clinical situation, I feel my body settle and my thinking getting sharper and clearer. That is incredibly important in high-stress situations where I need to make important decisions quickly."

Eliza Harrington Myers, M.D.Associate Professor of Pediatrics, Yale School of Medicine · Medical Director, Yale New Haven Children's Hospital NICU, Bridgeport

Dr. Leah Lagos is an extraordinary being. I've never known a greater empath. I've also had the good fortune of observing up close her HRV biofeedback training with elite mental performers. The vast majority have described the experience as some version of life-changing, and I've been blown away by the immense performance benefits.

Josh WaitzkinAuthor of The Art of Learning · 8× US National Chess Champion · 2× Tai Chi Push Hands World Champion

I learned to let go and can now shift my stress level, at will, using the tools that Dr. Lagos taught me. The work I've done with Dr. Lagos has changed my life, not only on stage but also off the stage. I find myself expanding and pushing myself into new territories.

Katherine CrockettPrincipal Ballerina, Martha Graham Dance Company

Dr. Lagos was there for me and my team at the University of Miami from day one. She took the time to understand my needs as a coach as well as the challenges that faced our players. She is not only a good listener, but a problem solver who helped to create solutions.
