Crossfit Altadena Coaches - Gabe

Gabe Perez

Head Instructor @ CrossFit North Pasadena


Gabriel began his coaching career at the age of 12 when he became the assistant coach for a youth football team; within 4 years he was the head coach of his own team at Kare Youth League and continued coaching for another 11 years. From teaching K-5th grades as a P.E. teacher to personally training private clients, Gabriel has dabbled in all types of fitness. Gabriel found CrossFit in 2009 after being sidelined by a Brazilian Jiu-Jitsu injury. Once he realized that he could compete in CrossFit, he considered CrossFit his new sport and never looked back. Gabriel graduated from Cal Poly Pomona with a B.A. in Counseling Psychology, and was determined to open his own box someday. In November of 2011 that dream became a reality. He has been able to maintain a competitive edge while simultaneously owning his box, and has found himself competing at one of the highest levels in CrossFit. In May of 2012 Gabriel ranked 25th in Southern California, one of the highest populated CrossFit regions in the world. Gabriel takes pride in not only being one of the youngest CrossFit box owners but also one of the most successfully competitive CrossFitters in the Southern California area.

Veronica Aguirre

Instructor @ CrossFit North Pasadena / CrossFit Altadena


Veronica grew up in north east Los Angeles and was involved in a variety of sports and teams throughout her childhood. All through college she had memberships at 24 Hour Fitness and the Cal State Fullerton rec center and was a self proclaimed gym rat. She would work out four to five days a week and was constantly on a search for maximum results. In the summer of 2011 she began CrossFit at the CFNP pre site establishment in the back yard of Gabriel Perez. In addition to crossfit Veronica participates in the occasional mud run and eventually began judging then competing in local CF competitions. In the fall of 2013 she took the CrossFit Level 1 training course and passed. This transition seemed like a natural progression to everyone who has trained with her and been on the receiving end of her advice and encouragement. You can now see her at CFNP on average five days a week pushing past her limits and comfort zone. She likes unicorns and bacon but not together, unless that becomes socially acceptable.
