Meet Epsy Tarchak

Epsy Tarchak, MS
Founder, Retrain Your Breathing

Epsy Tarchak is a breathing science specialist dedicated to optimizing energy, performance, and longevity through evidence-based breath retraining. Grounded by her M.S. in Chemistry, she integrates modern respiratory physiology with the Buteyko Method and Oxygen Advantage®, along with rigorously interpreted principles from Qigong and Pranayama—bridging ancient breathing wisdom with contemporary science.

With extensive professional training and years of applied practice, Epsy has worked with hundreds of individuals, athletes, and therapists worldwide while leading workshops, practitioner programs, and educational sessions focused on retraining dysfunctional breathing patterns. Her method improves CO₂ tolerance, nasal airflow, and diaphragmatic mechanics to enhance oxygen efficiency, nervous system regulation, and metabolic balance—resulting in increased energy, faster recovery, better focus, and improved sleep quality.

Originally from Paris and seasoned in high-pressure entrepreneurship, Epsy experienced firsthand how dysfunctional breathing impacts health and performance. She founded Retrain Your Breathing to provide a clinically compatible, measurement-based approach that begins with objective assessment (respiratory rate, nasal vs. oral breathing, BOLT/CO₂ tolerance, biomechanics) and advances through targeted, low-load interventions (“breathe less, better”) and personalized home protocols.

Epsy collaborates with functional and integrative physicians, therapists, and performance coaches to deliver protocol-driven programs and measurable outcomes aligned with client and patient goals—empowering people to regulate their physiology, restore balance, and sustain lifelong resilience and longevity.
