Meet The Owners

Although Athletic Perfection started as just an all-star cheer program, it offers so much more than that-recreational tumbling classes, private lessons, choreography, custom camps and gym rental.

Most importantly, Andrea, Jenn and Julie want Athletic Perfection to be known for developing strong, confident, hardworking athletes who take what they learn on the mat/in the gym and apply it to all aspects of life.



Founder, Co-owner

Athletic perfection was founded in 2002 by Julie Van Os. Julie is a third generation Tracyite who established a childhood dream of having an organization that pushed young girls to their fullest potential and also provided a safe, loyal, sisterhood.

“Growing up in Tracy, I longed for an elite sports program; I wanted to be pushed to excel, to be better,” Julie says.  “And growing up with six brothers, I was always seeking activities that provided the “girl” atmosphere that was so lacking in my life.

In 2012, Jenn and Andrea were brought on as partners which seemed inevitable since they were pivotal in the vision and direction of AP since its inception. Each owner brings their own expertise to the program yet all three are passionate about changing children’s lives for the better through the sport of cheerleading and tumbling.

“As mothers ourselves, we value our role in our athletes’ lives. We hope that in some small way, we can make their life better by providing a positive, safe environment where they can set and achieve goals while building life-long friendships like the three of us have, “ Julie says.




Andrea was one of Julie’s very first athletes at 16 years old. She embraced the program’s high expectations and quickly became passionate about the fledgling sport.

“I instantly fell in love with the gymnastics-like dedication and discipline combined with the fun of power tumbling and the creativity and choreography of the whole cheer routines, not to mention the practices surrounded by my BEST Friends- I was hooked… for life”




Jennifer was hired as a coach the very first year bringing her competitive cheer experience and contagious, fun-loving spirit to the program.

“After I graduated from Bear Creek High School as a competitive cheerleader, I immediately realized I could not live without this sport. The competitive edge had me hooked and having the opportunity to teach that and much more to the young children of Tracy was exactly what I wanted to do.”
