Do you sign a waiver to start ? I've been looking for a boxing gym to train in and hopefully compete. Also do you guys compete in the Colorado golden gloves?. Is there an age limit? I just gave 5 stars because I didn't want to be the one that ruins the 5 star rate... more

Today I took a 6 hour Women's self defense class here at the Dojo of Karate, and it was very empowering! Javier was able to show us ways not only to get out of any hold an attacker may try to use but how to counter with something that an attacker just won't be expecting! I just came home and practiced all of my NEW MOVES on my 6 foot tall, 200lb husband and I was able to get out of every hold he tried! I will be taking this class again in the future to make sure all of these techniques become natural instincts! My son has been attending karate classes at this Dojo for almost a year and he has become more disciplined and looks forward to going to karate every week.... more
