I'm a total beginner, have only trained here for a month. Coach Joseph is super kind and inviting. He's patient, knowledgeable, and great at breaking down concepts/moves in detail. The people at the gym are friendly and are all very willing to help you learn and train. This is a great gym to train at!

Since the move in 2020, the facilities are even better - larger mat space, separate and spacious changing rooms, bathrooms, and everything is new and cleaned regularly. The Sunday open mat is, as my coach called it, “Disneyland for black belts.” Coach Joseph makes an intentional effort to create a safe and welcoming culture, especially for women and children. I’ve referred my friends here several times.

Been to several gyms around the area and Cosmic is top notch. It’s a huge space that can accommodate a lot of people. You get a lot of different sparring partners. The people there are really friendly. Coach Joseph has a wealth of knowledge. He stays up-to-date with modern moves so you always know what’s working. He is also there to support those who compete and attend tournaments. This is a great place to train. Highly recommended.

I had very good open mat training there, very skilled instructors who created a no-ego and safety zone for high quality jiu-jitsu. Great for beginners and advanced practitioners.

I've been training here for 3 years and Cosmic has been one of the most welcoming places. The classes cover a variety of things, from the very new and modern to the very technical and even to the important basics. Coach Joseph is very knowledgeable and will help you to train your best. The space is also big and there are weekly open mats. I highly recommend for people of all levels

I've been training here for years. Really enjoy the classes and the coaching staff. Instruction aside the gym culture is inviting and collaborative. Everyone helps each other to develop their game.

Without a doubt the most welcoming school I've ever been to. Joe and his students have a phenomenal reputation with being the 626's largest jiu jitsu school to currently train at. Not to mention their Sunday Open Mats are probably the most popular in the 626. If you have kids or just want to train yourself. Highly recommended. Great for sport and art. Be ready to work, these guys don't play!

Love the classes. It's never boring. I can feel my muscles developing and my fat burning away while the frustrations of the work day melt away.

The atmosphere in the gym is very encouraging and uplifting, whether you're there to exercise or socialize, it's a good time. It's on the second floor with an amazing view at sunrise and sunset. 10/10 training here will help ensure you shed pounds!

This academy has really awesome culture of inclusion, teamwork and safety! I have a great time training here especially after a long day of work and school; it’s relaxing to empty to empty my mind and just focus on movements. Professor Joseph is amazing and he really make you feel like you are part of a family. Come train here and be part of the family too!!

My wife and I were looking for somewhere to drop in and train while we were in the area, and we're really glad we choose Cosmic. We were made very welcome from the get go, the teaching was exceptional, and it was followed by good, hard (but friendly) rolls. Joseph made sure we had a great time, and went out of his way to help us drilling (even though he had students competing at the weekend). He was kind enough to roll with us, and destroyed us with gentle precision. I had a chat and a laugh with everyone I rolled with, and they all had a great attitude, happy to discuss techniques and what worked and what didn't. We've dropped in to many schools while travelling over the years and Cosmic is amongst the best experiences we've had. Highly recommended to anyone in the area looking for a community and a hard workout. One more thing: their sprung mat is exceptional and I'd love to do some serious stand up on it sometime. Just the right combination of firmness and bounce, and much better than most of the gyms we're used to in the UK (even most Judo dojos!). Their facilities are excellent and whoever spent time putting it together did a great job.

What a wonderful gym! Great culture from top-down leadership. Coach Joesph has a clear vision of how he wants his gym run and elevates all his students to a high standard. A welcoming environment for both novice and experienced grapplers!

I come here for open mat. Really great people with great BJJ. Joseph is a very kind and caring owner, seems to genuinely care for and watch out for people. 👍👍

Instruction is comprehensive and well-structured, but I think Cosmic sets itself apart through its supportive atmosphere. Coach Joseph is very patient and understanding of each student's needs, and I have nothing but praise for how he runs his gym.
