Yoshinao Sasase
Co-Director of Physical Therapy, Performance Co-Director | MS PT, ATC, CSCS ysasase@catzsports.com
Yoshi comes to CATZ all the way from Iwata Japan via Cal State Northridge where he earned his Bachelor's Degree in Kinesiology and Athletic Training and then his Master's Degree in Physical Therapy.
Yoshi joined the CATZ organization in 2005 as a performance coach and became the director at the Yorba Linda CATZ facility in 2006 after the intensive training under the tutelage of CATZ founders Kevin Wentz and Jim Liston, and later directors Amado Garcia and Karen Corriveau.
As a soccer standout for Iwata Minami High School, he severely injured his back and found the recovery process difficult and not readily available. This proved to be the catalyst for his future career path. Upon recovery, Yoshi dedicated himself to becoming a physical therapist and helping others recover from and prevent back injuries.
Well accomplished, Yoshi has served as the assistant athletic trainer and primary physical therapist for USA Volleyball men's national team, Michael Jordan Basketball Camps, coached youth soccer. Yoshi's latest endeavor has been as a primary physical therapist for professional soccer club Chivas USA.
While Yoshi loves working with youth athletes, he is very passionate about working with geriatric patients. When he is not caring for patients you can find him enjoying time with his wife Yuki, hiking, surfing, and playing soccer.
