Had a couple mental issues with the food but got there. And every time I freaked out, Sara was so sweet that she helped me get back on track. Takes a lot of commitment.

Easton is one of the only places I've gone that I can say is amazing and has exceeded my expectations in every way I can think of. I personally train muay thai (they have muay thai, kickboxing, and jiu jitsu) which you can start training after you've achieved your yellow shirt in kickboxing since they want you to know striking fundamentals on the heavy bag prior to doing partner work. Not only is it a good workout, but you learn about proper technique, discipline, balance, respect, camaraderie, and so much more. I can't wait to see where else my training takes me!

Warmups were about 20-30 minutes and then we got into wrestling with a partner. A guest instructor came in from South America to teach us wrestling skills and some striking.

I inquired for private lessons and was contacted by Coach Sullivan. He gave me a price for which…read morewas I thought was very reasonable and decided to go ahead and take him up on his offer and training for ten sessions. When I get there the first time he was very professional , but talked very highly of himself, not very humble at all. For the first session all we did were a few stretching exercises for a full hour. Also, he was training me with someone else at the same time while he had a class going on. This was my first red flag. After my first session I inquired about the next session for which he informed me he will be out of town but to let him know my schedule. To get him to respond is a challenge, but I give him my schedule and we work something out eventually. Second session he was a little late due to illness. I understand illness, but if you're going to be late, I'd appreciate a heads up. I can tell he was not really into it and all we did was more stretching exercises. My private is MINE and it is valuable, but if you need to cancel, I understand. Third session is when we actually did something more than stretching and all that was added was kicking on the bag. It takes a few weeks to get a fourth session due to my vacation time and his schedule, but we finally get something scheduled. Again, he trains me along with someone else. Again, my time that I paid for is shared with someone else. For the fifth time, I arrive early and I waited for 10 extra minutes AFTER the time we were suppose to meet and he's still not there. I check the door and it was locked, so I leave. Coach Sullivan makes NO ATTEMPTS to contact me. I wait for a few days before messaging him telling him we are not a good fit for each other and I requested the remainder of the money I paid for unused sessions. He has NOT responded NOR returned my money. I have hired private coaches throughout the years and every one always respected my time, I learned something new every session, and all my sessions were PRIVATE, not shared with someone else. Communication was great between me and my previous trainers, and if a cancellation had to be made, it was always done ahead of time. For some reason my coach could not make a session due to prior engagements, I was informed beforehand. And none of them were arrogant or talked highly of themselves. Each one of my former coaches were extremely humble and were eager to pass on their knowledge. I could tell Coach Sullivan did not want to be there but his focus was never on me. His sessions were so far spread out, what was the point of going to him. I always met with my former coaches are a weekly basis as they always were given my schedule head of time. If you want private lessons from this man, do not go. You will not learn anything, poor communication skills, and he will more than likely keep your money.
