Fit Kids America strives to fight childhood obesity by inspiring kids at a young age to find the love of fitness. By incorporating movement at a young age, chances are kids will stay active into adulthood. Fit Kids America offers after-school programs that are convenient for busy families and fun for kids to participate in with all of their schoolmates.

Our own experience of more than 30 years coupled with our staff’s extensive background in sports and physical education have made the perfect combination for providing a structured class that not only teaches the fundamentals of a sport but also helps build self esteem and self confidence, which is a vital part of a healthy life. Let us introduce your child to something they will have for the rest of their lives.


Joan Missett-Gambill

President and Founder

Joan Missett-Gambill started Fit Kids America, a non-profit organization, in 2005 as a way to expand her existing Junior Jazzercise Franchise. As childhood obesity continues to climb, she began to see more clearly the fitness gap between what schools were able to provide and what our kids really need. As a result, we began creating new programs that would provide better fitness options for kids and their parents. We now have structured programs in most all sports and dance and engage with more than 10,000 kids a year!

After seeing physical education being put on the back burner at many of the local schools Hal wanted to bring back the fitness time that growing kids need. Hal also brings extensive sales and marketing experience from being a general manager at the North County Times for 20+ years and from years of coaching youth leagues as well as his own kids. His love for kids and sports makes Hal one of the most passionate people you will ever meet.


Riley Arsenault

Communications and Scheduling Manager

Growing up I always knew I wanted to work with kids! Fit Kids America was the perfect opportunity to start my path in making a difference. When Joan and Hal first introduced me to Fit Kids I knew it was something I wanted to be part of. I started off as coaching Art & Crafts to then coaching the sports I love! After graduating from California State University Chico with a major in Child Development I knew I still wanted to coach and work with kids, while also learning more about how the business works. That is when I got the amazing opportunity to work with the Fit Kids office team! It is the best of both worlds and I am so excited to continue bringing programs to kids all throughout southern California all while striving to positively make a difference in each and every class! 



Hiring/Training Manager

All my life I have been around and participated in many sports. When I was finally able to join school teams in junior high, I jumped on the opportunity to play basketball, soccer, softball, and volleyball. Getting into high school, I joined the volleyball, cross country, soccer, and tennis teams. Which then led me to pursue my tennis career in community college on scholarship allowing me to get a background in exercise science and athletic training. My college tennis coach had me assist with camps for local schools around the college, this is when my passion for coaching began. After a few months of living in California, I came across Fit Kids America and began working for them in September 2022 as a tennis coach. I have now been working with Fit Kids for a little over a year coaching many different sports and have loved every second of coaching the kids at various levels and locations in the San Diego area!




I have been a part of Fit Kids for over 8 years and I wouldn’t change a thing. When I moved to San Diego from Kansas my goal was to become an Athletic Trainer. I loved sports and wanted to help high school athletes. I found FKA and was hired on as a Hip Hop coach. I grew up dancing but was also a part of my schools winter guard! I also was a part of my high school tennis team finding a love for the technique. For Fit Kids I was a Hip Hop, Cheer and Tennis coach. I coached for two years and fell in love with the entire FKA organization. Moving forward to then work for corporate as their scheduling manager I was able to share my coaching knowledge to improve programs. Not only does FKA focus on helping students experience different enrichment so they can learn but I make it a goal to help my instructors grow their knowledge.




I’ve been with Fit Kids America for over 10 years & have had my franchise in the San Diego/Lajolla area for 9 years. This is my 35th yr coaching 5 yr olds up too professional womens football & many years of high school.
My coaching philosophy is simple, high energy, lots of kindness & be attentive to what works best for each child. Fun & being positive is my daily goals.
Thank you for being part of Fit Kids America.

I’ve been working with Fit Kids America since 2015. I am a San Diego native; a kid who grew up taking Fit Kids classes; a Fit Kids coach throughout college; and now Fit Kids franchisee. My goal has ALWAYS been about giving back to the communities I was once in, to share everything I know and love about Fit Kids America, and to play a key role in creating community ties! My favorite classes to teach are Cheerleading, Kickball/Dodgeball, and Volleyball. I love working with kids because no two days are ever the same!
