Tez Steinberg

ENDURANCE AND MENTAL PERFORMANCE EXPERT
SOUTH DAKOTA

Tez Steinberg is a distinguished endurance and mental performance expert who brings nearly two decades of experience in high-stakes environments to work with elite performers. He is widely recognized for spending 197 days alone at sea in a 23-foot boat, rowing over 8,500 miles nonstop from California to Australia across two historic expeditions. After becoming the first person to row solo from California to Hawaii without prior experience, his journey was chronicled in the documentary film The Row. Today, he translates these extreme lessons in self-reliance into actionable coaching for executives, entrepreneurs, and athletes. 

Tez specializes in a practice he calls Internal Navigation, which focuses on developing the emotional regulation, self-awareness, and resilience necessary to perform under extreme pressure. He works with high-achieving individuals to build the physical conditioning and strategic mindset required to succeed when facing significant uncertainty. His coaching is heavily informed by his own journey of recovery after surviving a heart attack at age 34, helping clients understand their internal patterns and navigate adversity with greater confidence and intention. 

Tez earned his MBA from London Business School and pursued additional studies at the University of Oxford and Macalester College. As a serial entrepreneur, he has led initiatives and teams that have raised more than one million dollars for mental health, education, and environmental conservation. His leadership and contributions to the field of endurance have been recognized by prestigious global organizations, including The Explorers Club, the World Economic Forum, and the Ellen MacArthur Foundation. 

When he is not coaching or planning his next expedition, Tez maintains an 18-year unbroken marathon streak that currently stands at 49 races. He is a passionate traveler and multi-sport athlete who has toured the United Kingdom and Ireland by bicycle and completed two Ironman triathlons.
