Paul Gummerson

Black Belt

Like so many other people, watching Royce Gracie dominate the early days of the UFC sparked my interest in jiu jitsu.  And like so many other people, I spent years telling myself that I was going to try it myself "someday".  Then in 2011 I realized that I was getting very out of shape and overweight and that I needed to do something about it.  I found a place to train and started my jiu jitsu journey.  I spent my first few years training at several different gyms.  Eventually, I found my way to 303 Training Center where I have been training ever since.  In January 2021 I was awarded my black belt by Professor Tony.  Since I've become involved in jiu jitsu I have competed in, helped organize and refereed hundreds of tournaments and professional matches. I have taught regular classes at 303 for years.  Jiu jitsu is my passion and I look forward to sharing it with all of you.

Jake Saltzman

Brown Belt

Never much one for team sports or exercise of any sort, Coach Jake needed a new hobby after high school to stay active and engaged. This is when he first stepped onto the jiu jitsu mats in 2009 and immediately fell in love. Jake's first experience was in Saginaw, MI where he grew up and he made it his first priority to find a new jiu jitsu academy upon moving to Chicago for school in 2010. Jake moved to Westminster, CO in 2021 and promptly found his home at 303 Training Center. 

This love affair instantaneously impacted all aspects of Jake's life, resulting in a new motivation to live a clean and healthy lifestyle, if not only to have better jiu jitsu. It was not long before Jake began applying the lessons he learned from jiu jitsu in regards to dedication, discipline, and problem solving to his personal and professional life. 

Jake's favorite aspect of jiu jitsu is the sense of community it creates. Having trained all across the country (and even abroad), Jake has found that jiu jitsu can act as a universal language and create beautiful bonds between individuals that may have otherwise never been connected. 

Jake teaches the advanced class every Wednesday at 6:30PM. Outside of jiu jitsu, Jake's passions include his family, spending time in the mountains, and obscure history trivia.

Mitch Evans

Brown Belt

Mitch Evans was inspired to begin his jiu jitsu journey after watching Gracie Jiu Jitsu and Pride Fighting Championship videos on VHS in the late 2000s. He arrived at 303 Training Center in 2013 and eventually received his brown belt from Professor Tony Basile in 2022.  He is a devoted father to a teenage daughter,  and a teacher at Mountain Range High School in Westminster, CO.  When he is not on the mat teaching,  training, or competing, he enjoys reading, doing stand up comedy, collecting vinyl records, and playing guitar.  His one piece of advice for anyone who is new to jiu jitsu is to "just keep showing up".

Hi there, my name is Aly and I'm a purple belt here at 303 Training Center! When I'm not at the front desk, you will always find me on the mat or talking to everyone here at the dojo! Jiu jitsu isn't the only thing I enjoy (I know shocker). I love music, traveling and relaxing with my dog!
