What Our Students Say
Hear from our community about how training at our academy has impacted their lives.
Aaron Todd
"I really love training at Catalyst and the open mats in Windsor were what drew me in. Its regularly 50+ people on the mats at all levels, sizes, genders and so on. People are incredibly friendly and the coaching is top notch. I've trained in few places around the US, Australia, SE Asia, and so on and you'd be hard pressed to match Catalyst on any metric. Great people, great BJJ, great facilities. Come and train!"
Nathan Murray
"Where do I start?! We home school our kids, we travel a lot with work. We are used to being outliers every where We go. It can be challenging moving state to state, sometimes country to country. One thing that is constant in our travels, is the friends we have found in Jiu Jitsu. Most gyms are good, but few are amazing. We have been fortunate enough to find Catalyst in Windsor. This is one of those amazing gyms! Not only do we get to train with great people, we are also part of an awesome competition team. This gym is endorsed by the most highly decorated competitors in the sport. Not to mention the fact that most of the people that train in this gym are high level competitors. Also, very humble. Very kind. Good down to earth people. We are proud, and fortunate to train at this gym. Professor Todd Cornfield, and his team of coaches, are top notch. Highest caliber in my honest opinion. My sons, went from having no friends, to having a team of gold medal people backing them up, and also winning gold medals themselves. To be clear, it’s not about medals. It’s about having fun, learning self confidence, challenging your self, meeting new people, and learning something new. The high-level coaching, team spirit, and philosophy of this gym, just happens to cultivate Gold medals as a byproduct of anyone willing to jump in there and give it a try. Our family endorses this gym. I challenge anyone reading this to try Jiu Jitsu. It’s a great sport for the whole family. In a perfect world, I would train 8 days a week at this gym."
Elio Gonzalez
"Dropped in at Catalyst BJJ in Windsor while visiting family and had a great experience. The class was well-structured , we started with a warmup that flowed into positional movements from bottom half guard, with Todd walking us through key details and concepts the whole time. After that, we did some positional training rounds focused on bottom half, then went into full rolling. I even got to roll with Todd, which was awesome, he is smooth, technical, and super helpful. Everyone there was friendly, welcoming, and tough on the mats. High-level jiu-jitsu and great vibes all around. I’ll definitely be back whenever I’m in town. Highly recommend to anyone visiting or looking for a solid place to train."
Ingrid Leidner
"After a long break, I am rediscovering my love of Jiu Jitsu thanks to the coaches and other students at Catalyst. The coaches are not only extremely knowledgeable and supportive, but also so welcoming. The atmosphere in this academy full of highly skilled athletes has been cultivated to encourage growth in a challenging and safe manner. There is a place for everyone, and I am so thankful to have landed here."
