Mary Jambon-Corzine Owner/She.E.O

Born and raised in Southern California, Mary started her gymnastics career in Gymboree with her mom. She competed through to level 8 by the time she was a freshman in high school, then she went on to do varsity cheerleading, and competed professionally thereafter until she was 22. She’s done music videos and workout videos, she’s worked in the solar industry and the events industry, and now is the She.E.O. of GymJambon.

Keaton Davis Xcel/Recreational Coach

Some people also know this young man as “the Flips for Tips guy!” Sonoma grown, Keaton started his gymnastics career at 8 years old, as an athlete at REG in Petaluma, where he trained and competed through level 9 in the boys JO program. He is super enthusiastic not only to be back in the sport as a coach, but to bring gymnastics to his hometown, and give back to his community the same understanding, discipline, focus, and confidence that gymnastics taught him.

Saige Calhoun

Although new to coaching, Saige has been with Sonoma Gymnastics Academy for many years! She started out doing gymnastics at SGA as a child, and now she joins our team, leading Babes/Toddler, Junior, and even Intermediate classes. Saige currently attends Petaluma High School and enjoys Flag Football.

Jessica Kunen

Formerly a rhythmic gymnast competing at the national level, Jessica has been with us for 2 years. Her experiences come in handy with helping little ones learn to be graceful and poised while still having fun. A happy mama of two children, she’ll be teaching our baby and toddler classes. Coach Jessica also makes lovely jewelry alongside being an amazing coach.

Aidan Patrick

Aidan comes to us with energy and raw skills in both Parkour and Gymnastics. He works with younger and older kids to bring out their athletic abilities while putting a smile on their faces. An avid video game player, he isn’t afraid to be nerdy and silly when the mood strikes.

Riley Haner

Riley has years of cheer and gym experience under her belt, and enjoys working with our smaller students. She can do the flips and stunts required to help inspire our higher-level athletes, while displaying the gentleness babes and tots gravitate towards. With a quick sense of humor and positive attitude, she’s a major asset to our team.
