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.

Our two kids had a great experience at Easton. I appreciated the staff from Fernie to owner Matthew…read moreand all the instructors. I could see our kids building confidence, even as beginners to these martial arts. I know "jiu jitsu" and "kickboxing" might be intimidating terms, but we found Easton is a place people come to improve themselves and experience community. I'm glad it's right there in central Boulder. Great people. Support this small business! Five Stars!

I can't say enough great things about this dojo. The new owners are an incredible duo. They…read moregenuinely care about these kiddos, you can tell. My kid loves going twice a week. Honestly, we'd go every day if we could. They both have a very positive influence in my son's life. Real life practical lessons, patience, and self discipline are a few of the main reasons we're so happy with trans boulder. Thanks for everything, you two!

I have been part of Tran's martial arts for over five years (with two longer breaks when I had my…read morechildren) and it has literally transformed my life. Not only am I more fit now at age 40 then I was at age 30. It is fun, it is challenging and rewarding mentally, emotionally and physically. I started when I was in a pretty bad physical condition and with the support to Master Tran, his crew and all the other members I have become fit. For the first time in my life did I find a regular work out that keeps my attention and that is FUN! Time flies by. The constant encouragement during class from instructors and persons I team up with makes me feel great. I get a super work out, and I leave feeling less stressed and calm. I'm clearly a better mom and wife after I work out at Trans. I am the type who loves skiing, tennis and other similar activities that keeps my mind engaged - the Muay Thai kickboxing is wonderful. It's almost meditative. I first started when I was studying for the bar exam, and this was the only time during the week that my mind was not stressing or thinking about legal problems. I often get bored going to regular gyms, or feel frustrated because I can't do certain work out or dance moves. This is the first time in many many years that I found a sport so fun, engaging, supportive and challenging that I kept to a schedule of working out 2-3 times a week! And I always felt respected for whatever level I'm at. People who are super fit as well as people who haven't worked out in years are equally welcomed. I'm from Sweden and we always go by first name, so in the beginning it was a bit unusual for me to get used to the "mam" or "sir" or to bow. But I got used to it quickly and it's really a matter of showing respect. There isn't a lot of formalities otherwise. It's a wonderful fitness and martial arts studio. Come and try it!

I have know the head Sensei, Kei Izawa Sensei and Mariquita Izawa Sensei for about 6 years and have…read morehad the great opportunity to train with both. IMHO, they are the most skilled Aikido instructors in the State of Colorado, and probably the Western region. Seriously. Kei Izawa Sensei is compassionate, kind, friendly and really gives his students the "True Spirit" of Aikido as well as the skills. Mariquita Sensei does as well. I will say that Aikikai Tanshinjuku is absolutely NOT a "McDojo"...when you progress (and you will), you go forward knowing that you've earned it, and that your progression reflects the skilla you've learned. This is not a dojo designed to "break you into submission"...it is challenging, yes, but never designed to injure or belittle any student at any level. TRAIN HERE!!
