★★★★★L. B.My daughter absolutely loves My Gym in Waldorf! The teachers are amazing — so patient, energetic, and genuinely caring with the kids. From the moment we walk in, everyone is welcoming, friendly, and professional. The classes are fun, engaging, and structured in a way that builds confidence, coordination, and social skills. It’s clear the staff truly enjoy what they do, and that makes such a difference. I’m so grateful we found a place where my daughter feels happy, comfortable, and excited to learn and play each week! Highly recommend to any parent looking for a positive and supportive environment for their child.
★★★★★James MortonWe have been coming to my Gym for 3 years and our experience has been incredible! The instructors are great and our child has developed physical skills that are unique to the environment they provide. Thanks MyGym!
★★★★★Gabrielle PearsonWe LOVE My Gym! We've taken both our 4 year old and our 1 year old, and it's been amazing for them. Staff and coaches are wonderful, and the kids have so much fun. Highly recommend!
★★★★★Alisa LebedevaWe’ve been coming here since my daughter was less than one. We always loved it and still love it. So much fun and always new things to learn!
★★★★★Christine HaydenOur 6 year old had the best birthday party tonight work all of his friends. We are so happy we discovered My Gym. The place was awesome, clean, the party started right on time, we could not get over the ease of everything. The party room was all set up nicely and food on plates for the children (it was as if a party ninja which in to do it all). The website is great, texts and phone calls to organize great, but the best part was the ladies working. These three looked like they were genuinely having just as much fun as the kids!!! I want whatever they put in their energy drinks... they were phenomenal with the kids. An 18 month old got extra attention with them, too, and they pulled out special toys just for him. We loved all the games, too. These ladies deserve large paychecks, they were awesome. Thank you so much!
