Our Staff

Sara Hernandez Kemp

Hello! I am the founder and co-owner of Gemstone Gymnastics, along with my husband Chris. I opened Gemstone because I believe that EVERY child benefits from gymnastics.

Gymnastics provides so much more than learning cartwheels-it increases confidence, instills a lifelong love of physical fitness, supports academic achievement, and so much more! I wanted to create an environment where every child, no matter what their abilities or goals in gymnastics are, will find a supportive, encouraging and fun environment to play and grow. At Gemstone we equally value all of our students, from the baby class through the highest competitive level, each child is precious to us!

I began coaching gymnastics in 2005 after many years as a gymnast, cheerleader, and dancer. I have coached all ages and levels of gymnastics from babies through teenagers including competitive teams in the Junior Olympic program. I graduated from the University of California, Davis in 2008 with a major in Communication Studies and a minor in Child Development. I have multiple coaching and safety certifications from the gymnastics National Governing Body, and am a current certified high school and Junior Olympic gymnastics judge. Continuing education in my field is a passion of mine, because I believe in learning from the best to be the best for YOU!

Chris Kemp

Hi I am Chris, co-owner with my wife Sara, and CFO of Gemstone. My background is in business and finance, which means I am a behind the scenes guy at Gemstone.

I don’t teach any classes, but I work to keep the business running smoothly in the office. Sara has taught me everything I know about gymnastics – including how to do a cartwheel! Although, I’m not sure you’d want to see that, it isn’t very pretty!
