Meet Our Partners!

In addition to Onsight’s staff, we also rely on our partners for synergistic fitness services at our location. PacWest Endurance provides personal training and coaching services like outdoor bootcamp, indoor cycle class, and group runs on the premises. Karina Polanco-Jimenez not only works as PacWest’s personal trainer and coach, but also with Onsight’s doctors to manage our front desk and instruct rehabilitative exercise programs to our patients.

Karina Polanco-Jimenez, CPT

Front desk manager and certified personal trainer
Coach with PacWest Endurance

Karina joined the Onsight team in 2019, bringing with her an inspirational set of life experiences. She believes that sports and fitness significantly impacted her life, overcoming many challenges. Team sports gave Karina a sense of belonging, confidence and courage that led her on a new adventure to earn her Bachelor’s degree from Cal Berkeley. She has been a competitive triathlete since 2017 and with the help of her PacWest Endurance coach and team, she represented Team USA at the Triathlon World Championships. Having transitioned from a broken family and eating disorder to an active and healthy lifestyle, Karina found her passion in helping others to overcome life challenges. She loves her work as a personal trainer and endurance coach, especially when witnessing her clients regain their true highest expressions¬†of themselves through exercise.
