It looked trendy, new, up to date, and the ac was even running chilly...I just didnt get to see what was upstairs or the bathrooms. Professor Ian was great with his big voice quickly straightening up students. He's stern and professional with a smile on his face. I appreciated that he was efficient and fast with instruction, running exercises, and rotating the sparring partners. The main professor was well spoken about by the GB Denver crew, but he wasnt present. We'd love to visit again!

People there are friendly and welcoming but still serious about getting better, they take their training seriously but it's a relaxed vibe. The instructors are wonderful, very professional yet personable. High level techniques being shared here. With soo much experience on the mats you have lots of different Jiu-Jitsu styles to choose from. The amenities are exceptional. Nice clean bathrooms, changing rooms and showers. The front desk people are always smiling and helpful when you come in the door. While I haven't gotten to train the striking classes as I primarily train Jiu-Jitsu , they look like a lot of fun and they are training very hard with solid technique. They have lots of quality mat spaces for grappling and striking as well as workout equipment. There are many classes for people to choose from. Giving the most flexibility I have ever seen at a gym. Add in the elevation and the location of a beautiful mountain city, this is one of the best places to train in the country. I highly recommend the gym.

Didn't attend for a few months and realized I was being charged still. Played phone tag for 3 weeks trying to cancel just to have them finally tell me I need to come in in person to sign. This was after I told them that it is no longer convenient for me to attend do to over an hour commute and change in work schedule. I came in one day at 4:30, not realizing they are completely closed. Called hoping I could get an answer but there number just sends you to a voicemail EVERY SINGLE TIME. They are worse than big corporate gyms with how they handle someone trying to cancel. Minus 1 star for lack of class availability. 10am and 7pm being the only times for a newcomer to make a class is tough. Minus 1 star for muay thai training. Paying $200 a month and spending multiple classes doing ladder footwork drills that the head coach did in high shool is a bit silly.

Master Kim makes the classes very approachable for small children and adults alike, with classes based on age range/belt level, with many options to choose from each week. It is a wonderful community. I especially appreciate Master Kim's sense of humor and patience with the little kids. He never gets frustrated even if he has to tell them about 20 times how to do a movement correctly.
