After going through my own fitness journey, I found a love and appreciation for fitness that ultimately led me to open WRK Fitness studio to provide the best possible training experience for my clients and fellow trainers.

Born and raised in Southern California fitness has always been a passion of mine. After taking my first class at 16, I fell in love with training and group fitness. I loved how engaging and encouraging the instructors were and knew it was something I wanted to do. After completing my fitness certification I continued to learn new aspects of training to better serve my clients and help them meet their goals .
