Reviews
Our son Hank joined in June and he loves it. The class is a mix of discipline, learning, and fun. I don't have to bribe, beg, or force my son to go. He looks forward to it. Marcos is a great teacher and truly cares about the kids. We highly recommend Merced MMA. It's a safe affordable place for our kids to learn how to be confident capable individuals.
In the gym twice during a visit to Merced [day pass]. First-rate facility. Obvious knowledge. Pride and respect from the members and staff. If you are looking for support with whatever goals you have [beginner/intermediate/advanced], this is the right gym.
It feels like family here. They hold their students accountable for their achievements; they don't just give them away. They assure you that you're getting quality training. Learning: skill and strength. Understanding: patience and value. I recommend hands down.
This place has awesome coaches. The staff & teammates are nice and helpful. It's big. The men's & women's bathrooms are always clean. I highly recommend this place. 5 stars!
Best place in Merced. Like the best people, you could wish to meet are here. If you are looking to improve your life in any way at all..... go here.
This is a great place to train. My kids love coming here. This is a place where you walk in and feel like family. Professor Marcos teaches respect and discipline and expects the kids to train hard. I love that!!! He also teaches our kids to be confident in what they do. I highly recommend Merced MMA.
