Considering how many businesses are failing on Long Island due to COVID, you would think serving your community would be number one priority. Clearly some of the employees have forgotten that phone sales are a massive relay.. being attentive, not having an attitude, and clearly engaging with other employees by making faces or mouthing comments or rolling eyes to hear other employees laughing in the background.. this is extremely disappointing and a very poor representation on what an MMA family should embody.

As a parent with a young child in the school, I will not present this as a long-term relationship…read morewith the school, but as the impression of someone new. My child is new there and new to martial arts. I have read some of the other comments that criticize the techniques that some of the students may be learning and that they are moving through the belt system too fast. I will look at it from an opposite view. I too was a young martial artist. I had some instructors that actually made me scared to go to class. They were too harsh for someone my age and as a beginner. With years of martial arts under my belt, I also walked in with criticisms in my mind forgetting that I once was a child. I want to walked as a very young boy not even a teenager yet into very intimidating schools run by adults. Although the unnecessarily hard hits, bad breath yells in my face and general "cold" dispositions may have made me tougher, but did not encourage my preteen self to want to go to class. This school has employees that are warm and embracing to the youth. In addition to the martial arts they encourage character growth in young children. For me, it's important for children to learn the foundations of martial arts Young. Proper stances, proper ways to punch, proper blocks and so on. As my son gets older, I will direct them more towards a specific discipline that he can master. He currently likes attending this school and is motivated to go . When that changes, the school is going to change. I will offer a long-term review later based on his training results. For now I am comfortable with this environment for a young boy.

They aren't shy to compliment kids when they do things right and correct them when needed. - the environment is very friendly, fuzzy and warm. We feel at home. Mr. Minerva should be known as Mr. Charm. He simply can't hide his Italian hospitality and flamboyance. - The program is not cheapest, but it's totally worth it. We did a trial at another school as well that was like $20/month cheaper, but not anywhere close in quality to Makoto. Shihan Minerva and his team don't just teach self-defense. It's the discipline and confidence that makes the difference. I would give it 10 stars if I could!

They have an area with tables and chairs to hang out on. Theres an area with a long wall of mirrors you can do your own workout on, and obviously the cage and a big area with just punching bags. The bathrooms were super clean. They do only have 3 shower stalls, so I can't imagine how busy it is in the morning. The sauna room is really small. The front desk guy was friendly to us. I mean for what they have and the amount of classes, I say this is definitely worth it, compared to another UFC gym I've seen.
