We had my son’s 3rd bday party here this past weekend and it was AWESOME!! My son loves this type of pretend play where everything is his size. Pretend to serve ice cream or pizza, pretend rescue or fish, etc. The large climbing structure had even our older teenagers climbing and playing chase with the younger kids. Everything was CLEAN and organized. Staff was super friendly and accommodating. If there were bonus stars, I’d give more!

We love Tier One Gymnastics Academy! We have two daughters here, one in competitive and one in rec/pre‑team. Both programs are excellent. The coaches, owners, and gym families are amazing. The facility is new, clean, and well maintained. We have had birthday parties in both the gym and Fun Zone, which have also been great. Highly recommend!

★★★★★Rochelle Bueter

Our son enjoys the tumbling class for pre-k. He has had a few of the teachers and they have all been kind, patient, and understanding. Our son is learning new skills such as hand-eye coordination skills, along with following directions. We've also had our son's birthday party in the FunZone and it was 100% worth it. The FunZone is a HUGE perk for our small town

Our daughter transferred to Tier One when it first opened last summer. It has allowed our daughter to advance in gymnastics more in 8 months than the three years prior somewhere else. Small class size allows more one on one help from the coach. We had our daughter’s birthday party in February. It was a large group of 1st graders and Darian was hands down amazing. She had games and activities for the kids and did her best to keep them involved for the one hour before we went over to the fun zone. Cupcakes and table cloths were included. One of our favorite things which may be small and silly to others is my daughter walks in the building and is greeted by her first name. This just makes us feel like the staff truly cares and we are not just another number. Our family is thankful for Tier One!

We love Tier One! The coaches are hands-on and great at meeting individual needs. My sons love ninja—it challenges them and helps with other sports. My daughter does gymnastics and cheer, and cheer is the highlight of her week! The sibling play area is a huge bonus for families. Highly recommend!
