Services
Diamond Gymnastics is proud to have a competitive gymnastics team that competes in the USAIGC program. Join us in cheering on our team for the upcoming 2020 meet season! We are proud of our Team and the way that the girls represent Diamond and enjoy each other while they continue to improve their skill, encourage each other and show their Team spirit!
Our philosophy for children ages 15 months to 4 1/2 years is to teach gymnastics and fitness in a fun, safe environment with the objective of promoting basic coordination and raising the child's self esteem. Diamond's classes are designed to include physical movement (jumping, climbing, tumbling, running, etc.) mixed with fun, to encourage motion skill development, coordination and confidence.
For the 2021 Summer and Fall Sessions we are offering ONLINE ENROLLMENT. Please note that select classes (peak times, advanced levels, etc.) are unavailable for online enrollment. Please call the gym at 973-560-0414 to enroll for these classes. Pre-School classes are offered in the morning each day Monday through Saturday and during the early afternoon on weekdays.
Two unique, fun-filled ways to celebrate birthdays and special events are offered at Diamond! Gymnastics Parties feature one hour of gymnastics fun and a half hour in a large private room for gifts and refreshments. The gymnastics hour includes organized play utilizing Diamond's trampolines, foam pit, parachute and much more.
It's thrilling, it's challenging, it's a great workout and it's here at Diamond City Sports. Rock climbing is one of the fastest growing sports and one look at the Diamond Rock Mountain will tell you why. Climbing at Diamond Rock Gym is not limited to experienced climbers. It is truly a sport that can be enjoyed by the entire family.

Beautiful facility but do not respect ANY sort of covid mask policy. There are tons of unvaccinated kids running around with no masks. Everything is optional and they are completely not in line with ANY of the other local gyms that have a mask policy - especially during a surge. They lost a lot of customers from the community we live in because they are too lax with covid policies.

This place is very good for birthday parties. Kids love be here.
And during the day they have classes for different age of kids. Kids are jumping, rolling, running, hanging, hopping... So much fun. I love all activities what they do.
Some teachers might has too little experience, but that is fine.

First of all, I grew up doing gymnastics and visited many gyms over the years of competition. I have NEVER seen one as clean and as well kept as Diamond! The gym is also unusually large, offering a diverse range of equipment to entertain young children. If you haven’t gotten to meet the owners, they are very kind, generous people who have gone out of their way time and time again to help others, and expecting nothing in return. Over the years, I have gotten to meet a few of their coaches and they are very kind, talented, and responsible people who are there to engage your child and give them

Facility is huge and clean with adequate staff and equipment. There is separate viewing area for the parents and visitors to watch over their kids practice. I was able to enroll my daughter for the spring session online on a weekly basis(slots filled pretty soon). But unfortunately I had to drop her from the class after the first session and reached out to the management over an email. They were pretty quick to respond and understood my position and helped me with a refund. I would definitely recommend this place for your kids.

My kids love summer camp at Diamond Gymnastics. They did a lot of fun activities like water play, rock-climbing and crafts. They also like to demonstrate some cool gymnastics moves they've learned when they get home.

Just had my daughter’s 4year Bday party there. All the kids had a good time no matter gender and age. This place is huge and has a good set up. The staff on floor are enthusiastic and they work really hard. The cleaning staff is very responsible. The management there is organized. New location, new renovations and new parking lot. Love it! Quite some parents went to get their party information right in the middle of the party. 😁

We booked our daughter's birthday party here. Unfortunately, our plans changed. We contacted Diamond Gymnastics, with only 3 weeks until the party was scheduled. The owners said they would refund our non-refundable deposit if they could book the scheduled time with another party. And guess what - they did. That is a really class move. 5 stars for professional, honest places like this!

We attended our very first birthday party at Diamond Gymnastics this week. The children had a wonderful time and the person assigned to the party was very enthusiastic. Everything seemed pretty well organized since the gym is large enough to accomodate multiple groups. As a parent, I did not love the area set aside for the food. All parties were held in one large area and would love to have seen individual party rooms. The kids didn't seem to mind and after all, this is a kids' party. All in all, I think kids of all ages would love this place
