★★★★★Kate DeRosaThe perfect place for a 3rd birthday!! We have been loving Diamond Gymnastics for mommy and me classes since my daughter was 18 months. Today we had her 3rd birthday there and I can’t say enough great things. The place was clean, organized and ready for us. The staff was warm welcoming and oh so happy to be helping the kids. The party structure was perfectly developmentally appropriate and let everyone access the fun the way they wanted and the flow was so smooth and stress free. I am so glad we chose to have her party there and will be recommending it to everyone 🥳
★★★★★Yisel LavalleMy daughter has been part of the team for gymnastics for years. We absolutely love all of the staff here. Everyone is there for the kids and it is such a fun environment that my daughter has not only learned so much but has also made some great friends with other gymnasts. It is such a clean environment and everyone from the staff to the front receptionist are such great people. We came from another gym and this truly was a great gym to come to!
★★★★★Shari Markese⭐️⭐️⭐️⭐️⭐️ We absolutely love this gym! We’ve had such a wonderful experience here over the past few years. From amazing birthday parties to fun-filled summer camps, and even end-of-year celebrations for my son’s school — every visit has been nothing short of fantastic. The staff is always friendly, organized, and great with kids. The coaches know how to keep things fun while still teaching real skills and encouraging confidence and teamwork. The facility is super clean, safe, and full of energy — my kids never want to leave! Whether you’re signing up for classes, planning a party, or joining a special event, this gym goes above and beyond every time. We’re so grateful to have found a place that our whole family enjoys. Highly recommend!
★★★★★Guido UrzuaDiamond Gymnastics has been amazing for our family. The coaches are super encouraging, professional, and really know how to connect with the kids. You can tell they care and take pride in what they do. The facility is clean, organized, and always feels safe. My kid has grown so much in confidence and skill since starting here — it’s been awesome to watch. They do a great job pushing the kids to get better without taking the fun out of it. The staff is friendly, communication is solid, and it really feels like a community. If you’re looking for a great gymnastics program, I highly recommend Diamond.
★★★★★Benjamin ShumanMy daughter has been attending summer camp each year at Diamond since she was tiny. She loves it there. The staff including ownership are kind and caring, the student counselors they hire for the summer do a great job and care about their students. She’s had birthday parties there and they have always been a success. It is a great environment for kids and she looks forward to it every summer! Highly recommended!
