About Us
Our Philosophy
Since opening our doors in December 2017, Grassroots Gymnastics has become a vibrant place where kids of all ages experience the joy that gymnastics can offer! We believe that gymnastics is so much more than just a sport – it’s a tool for teaching life lessons that will help kids grow into confident, happy, and resilient individuals. Every day, we are humbled by the opportunity to do what we love and share that passion with the next generation.
​
At Grassroots, we value FUN, hard work, respect, integrity, and positivity. These aren’t just words to us – they’re the foundation of everything we do. We strive to inspire kids to work hard and push their limits, all while maintaining an unwavering belief in the power of a positive mindset. Our goal is not just to teach gymnastics, but to help our athletes become the best versions of themselves, both on and off the mat.
​
The name "Grassroots" means something deeply special to us – it represents community, growth, and holistic wellness. We see ourselves as an extension of your family, dedicated to creating a space where children feel safe, valued, and empowered to be their true selves. We are here to nurture their growth in every way possible, helping them build confidence, friendships, and lifelong skills.

We can’t wait to welcome you into our gym and share in the incredible journey ahead!

Head Coach and Team Director
Welcome to Grassroots Gymnastics! Gymnastics has been a central part of my life for as long as I can remember. I competed in gymnastics for 10 years at Hill's Gymnastics and continued my passion by joining the college club team at the University of North Carolina Wilmington (UNCW), where I earned a degree in Health Education.
My coaching journey began in 2003, and since then, I’ve had the privilege of working with many young athletes in North Carolina, California, and now here in Charleston. When I founded Grassroots Gymnastics, my mission was simple: to create a safe, welcoming space where every child feels empowered to learn, grow, and thrive.
Beyond gymnastics, I’m a passionate learner who believes there’s always more to discover and share. When I’m not in the gym, I enjoy cooking, playing golf, traveling, and spending time at the beach and with my dog.
Thank you for being part of the Grassroots Gymnastics family. I can’t wait to see your child grow and succeed in a space built for them to shine!

I grew up in Emmaus, Pennsylvania, a small borough about an hour north of Philadelphia. The oldest of three kids, I was always on the move and my parents were tireless in getting all of us to our various team events and school functions. I was involved in baseball, basketball, ski/snowboard clubs, golf, committees for my high school and soccer. Soccer was finally what became my calling and was consumed by the sport. After excelling at the club level and being named to the Emmaus High School Varsity squad, I began to realize the positive impact not only my parents had on me but also the coaches I was surrounded by day to day.
​
More than just soccer coaches they all laid life lessons out there for us to take. They are more like life coaches than just the leader of a sports team. Many of the lessons I live by today are directly from my soccer coach Rene Rawhouser. The obvious lessons were for sportsmanship, work ethic, and perseverance but I also found humility and kindness and nutrition.
​
​
I have always had an aptitude for leading. Not always from the leader’s position but from anywhere in the group. With simple words of encouragement or by being an example, I love the opportunity to help another grow as an athlete, tackle their fears, or just become a better human. This is coaching to me. To be a good leader you have to be a good learner, and coaching teaches me every day. I never want to stop coaching. Grassroots Gymnastics is my platform for my coaching career and I couldn’t be happier to have the opportunity to shape young lives and give little tidbits of life lessons to the athletes who come through our program. Maybe a few remember me and a life lesson or two 20 years down the road.
