Vernon Leopold Vargas II

Owner / Head Coach

It is a privilege to witness the sense of accomplishment children have when learning skills, the joy kids have when entering the gym, as well as the pride parents have in their children’s success. Personally, there is no greater joy than watching children develop physically and mentally while having fun and staying active. My passion for the sport began when I was 6 years old. . After 11 years of competitive gymnastics, however, I made the natural transition to coaching. I have been a gymnastics instructor for over 27 years. Many athletes have won medals and national titles while under my instruction.

I have a passion for teaching children of all ages and abilities, spending numerous years in daycares and schools teaching gymnastics/dance. I am certified as a preschool coach. I currently work at Circle of Friends Preschool as a gymnastics movement and cheer coach. Not only am I a USA Gymnastics Certified Member in five disciplines; Artistic Boys & Artistic Girls Gymnastics, Sports Acrobatics, Tumbling & Trampoline, and All-Star Cheerleading, I have Level 1 certification in gymnastics and trampoline. I developed the All-Star Cheer and Tumbling &Trampoline programs at other gymnastic facilities. I also have Level B certification in emergency first aid and CPR. In addition to my work in the gym, I hold an Associates of Arts degree in dance movement from UC Irvine. I am the current Northern California State Chair.
