Gold Medal Gymnastics & Ninja — Local services in Millburn

First, I want to start by saying that I really don’t like leaving negative reviews. What I dislike even more is when people lie to me and try to make a fool of me.

On Saturday, 2/15, I scheduled a private lesson for my son for Saturday, 2/22, at 1:30 pm. I spoke with both our instructor and the lady at the front desk (Ms. Emely) and made sure we were scheduled for that time.

We arrived at the agreed-upon time, 1:30 pm, only to be told that our class was canceled because of a party booked for that day (parties are usually held on Sundays). However, I did not receive any notice beforehand—no text messages, emails, nothing. Of course, I was upset. I had planned everything for that day and canceled other commitments that conflicted with the timing.

Before leaving this review, I tried to communicate with them.

The young lady at the front desk, Ms. Emely, instead of apologizing for the inconvenience they caused, chose not to take responsibility. Worse, she lied to me, looking right into my eyes and telling me that it wasn’t her with whom I scheduled the appointment. She tried to make a fool of me. I concluded that it was no use talking to her anymore. She should be ashamed of her lie. (I’m not against her—she’s a young, beautiful lady who really helped me out that day to arrange everything.)

I left because I felt really bad. Imagine someone telling you it wasn’t her with whom you spoke, and you know it was her.

I tried to call them later to speak with the manager. I was told that the co-owner would get in touch with me. I waited. Silence. No one reached out to explain themselves. I understand it was a Saturday, but it wouldn’t have taken much time to simply dial my number, listen to what I had to say, and apologize for THEIR mistake.

The most frustrating part of this entire situation is that nobody seems to care at this center.

Update 2/24

The co-owner, Justin, contacted me the next day. He turned out to be a very pleasant person who is just as interested as I am in resolving this issue. He explained to me that this was their first time dealing with booking a private lesson for Ninja. Since it was their first experience, mistakes are understandable. He made it clear that this will not happen again in the future with any other members. I really hope and believe that. We were generously offered two free private lessons, for which I am...

Gold Medal is really cool. The fact that they have so much to offer is great. I love how they allow you to "try before you buy" because it's so difficult and inconvenient to have to commit to something for your child when they have no experience and may or may not actually enjoy an extra curricular. Every staff member I have encountered was genuinely pleasant. I personally feel like placing the kids in the classes is easier said than done because not everyone is a perfect fit/can benefit equally from the same experiences. I have been wanting to get my daughter and niece signed up, but we still haven't quite figured out what works best for each child. Ideally I'd like to get them signed up for the same class, but when we tested out the ninja class vs. the gymnastics class, there seemed to be a disconnect. I'm not sure if the class size was too large or the instructors don't put as much care/effort into the "temporary/just trying it out" kids...but something just wasn't 100% for either of "my girls." We are not done trying though. We will return when our schedule allows, to see if maybe a tumbling class may be optimal. It's just hard to know with kids in new experiences too. I also love the fact that GM offers the "camp days" during days when kids are off from school. We haven't been able to join one just yet, but the idea of it just seems awesome...

We hosted our child’s birthday party at Gold Medal Gymnastics & Ninja, and it was such a wonderful experience — highly recommend it!

🏃‍♂️ The gym is spacious and full of fun activities, including inflatable castles that the kids absolutely loved. There were 2–3 staff members leading games and keeping everything organized, while parents could comfortably watch from outside through the glass and on-screen monitors. The playtime lasted about an hour — the kids had a blast and burned tons of energy!

🎈 The party room was beautifully set up — clean, colorful, and decorated with balloons. The staff handled everything from serving food and drinks to cutting and serving the cake, and cleaning up afterward.

🍕 All we had to do was to bring the food and drinks — they took care of setting everything up for us. At the end, they neatly packed all the gifts into two large bags for us to take home, which was such a thoughtful touch.

💛 The staff were all incredibly friendly, professional, and well-trained. Everything ran smoothly from start to finish, and both kids and parents were super happy.

We’ll definitely be coming back in the future — thank you, Gold Medal Gymnastics & Ninja staff, for making our kid’s birthday...
