I cannot say enough things about the professionalism and just concentrated experience and knowledge that is collected in one place. I have been going here for almost 6 months when the COVID restrictions and shut downs would allow and cannot express how passionate the staff and coaches are. It is impossible to attend a class here and not feel how dedicated they coaches are to their craft and to passing it on to their students. It is a fine balance between teaching such a unique craft while not making it feel overwhelming for a newbie like me; a balance they strike perfectly every time. I would strongly recommend the classes here for anyone interested in learning Muay Thai and getting fit in the process.

Nothing can beat lifetime. Best accommodation, services and worth the price. Might be expensive, but it’s worth every penny. Great instructors and variety of activities

Amazing atmosphere for anyone looking for muay thai, bjj, or mma. They take their time to teach you and make you feel part of the community. Cant recommend this place enough!!

I trained there from 2002-2004. Twenty years later I have never seen instructors better than these guys. Great gym, great instructors, no frills real deal gym.

It’s okay. Non thug environment and friendly. Best trainers in the Boston area in my experience and worth the money. No matter how good you are you can get better here. Plenty of pads and heavy bags. The owner and trainers are a close imitation to Muay Thai but not 100% authentic fundamental Muay Thai despite what they may think; no surprise since none of them are Thais. Closer to being 100% than the rest of the gyms in the area however, and more comprehensive. No showers here for when you’re finished and sweaty.

First impressions for a martial arts gym are everything, and this place sets the bar high. The knowledge and reputation are first class, and the renovated upstairs is perfect. Trainers and students have always been respectful. Id still be there if I didnt move across the country...but I make a point to stop in and train a couple times when I come home on vacation. Get in and train, you can do it!

I was in town for the weekend and dropped in on the Saturday 10am all levels class muay thai class. Great instructor and welcoming group of people to train with. I would definitely go back next time I am in town!

One of the best gyms to learn Muay Thai!! The trainers are super nice and very professional. If you want to learn this is the place to go!❤😊🙏

Loved my time boxing there with Coach Massey and Coach Lyle! Miss it every d a m n day. I wish I lived closer...

Hands down best gym on the east coast! Very knowledgeable and caring coaches with high intensity training with the best competitors in New England. #DellagrotteKarate all the way.

Great Muay Thai and MMA place. Great team and coaches. Highly recommended!

I first tried getting ahold of Kru Mark on Tuesday morning. I was told that he was out of the office for the day but that he would return my phone call the next day. I did not hear from him so I called again. No one answered so I left a message. It is now Friday and I have left 4 messages and no one has called me back. I finally decided to reach out to another gym today. I called the gym about an hour ago and the owner already got back to me and we set something up right away. Disappointing!

No better place to go if you want to train with the best, learn from the best, be the best.

I known Kru Mark about 20yrs one of the Best Instructors in mauy thai every also the Best School in Boston ..

The best muay thai team!!!!

Simply.Amazing
