Katharo Training Center - Jiu-Jitsu and Fitness

“A huge shout out to Steve. The amount of dedication he puts out to his students is amazing. All levels of students are welcomed, and treated the same. Steve served his country, and still serves the community. With hard work and dedication dreams can be fulfilled at Katharo training center.”

“Best BJJ Academy in the area hands down. Veteran owned and operated. Professor Steve is top notch, his staff is top notch, I can’t say enough. World class instruction in a fun and safe environment. I have done multiple seminars with a few big names and his approach and practicality to jiu jitsu is second to none. Very fortunate to have Katharo so close to home. If you’re thinking about checking out jiu jitsu, this is the place to go!”

“Incredible martial arts training center for kids and adults alike! I dropped in while on a work trip for a class and private with Steve (owner and professor) and was immediately greeted with kindness and authenticity. Knowing I’m older, they worked with me appropriately and I could immediately see they do the same (and have classes) for people of all demographics. I was taught Gracie BJJ moves that would work for self defense skills as well as for someone wanting to engage in competitive Jiu Jitsu/Grappling/Muai Thai/Wrestling. Also enjoyed the full gym, showers, saunas etc. Highly recommend to the families in Littleton/Denver looking for world class instruction and wanting to get into, or level up, their self defense, workout or martial arts game!”

“I highly recommended the Katharo training facility. I take the striking classes with coach John as well as the conditioning class on Saturday morning. He is an excellent coach for all levels from beginners to those advanced fighters. He never makes you feel discouraged, rather encourages everyone regardless of their ability, The Saturday fitness class is great. Hard work for an hour then it’s done Everyone at the gym is super nice and the facilities are always clean”

“Steve and all of the instructors there are the best mentors I have had in training martial arts. I came from other MA backgrounds and began to realize BJJ/JiuJitsu is the best for self defense, fitness and has practical applications to anyone, including law enforcement, first responders and other whom have to deal with hostile people in their profession. We have classes and training opportunities 7 days a week, so the money you spend is worth all of it. You do not have to be a cage fighter to train with us, everyone comes to train, little to my age. Kids classes, wrestling, Muay-Thai & MMA, BJJ and self defense classes are taught every week. Discounts for veterans and first responders apply as well. Regardless it's a great price for great training. As of 2025, I have been there for 4 years and at the age of 54. I plan to keep training until I can't. If I can do it at 54, so can you.
