What Our Students Are Saying

A good friend referred me to CSW several years ago. I was looking to keep in shape and learn self-defense techniques. I have to be honest, when I first began training in Jiu-Jitsu it was a bit overwhelming because of my age and gender. With the help and encouragement of Sensei Erik, Coach Tonya, and fellow teammates, things began to fall into place. I quickly began to feel a part of the CSW family. I highly recommend women of all backgrounds to take Jiu-Jitsu. Jiu-Jitsu builds confidence and self-esteem. You truly learn that you can defend yourself no matter size, age, or weight. See ya on the mats!

The knowledge Coach Paulson has amassed in his lifelong pursuit of martial arts training is truly unrivaled. To be a part of his lineage is a privilege. He is a rare link to pure BJJ and Submission Wrestling.

Myself, husband and 8 year old son have been members of CSW for several years. We initially enrolled our son in their kids MMA program when he was 5. My husband and I were members of another gym and didn’t intend on joining.The amazing trainers, coaches, atmosphere, and family friendly environment were amazing and too much to resist. Now, all three members of our family are full-time members! We all train at least 3-4 days a week.The classes are amazing! The workouts are great for anyone, from a fitness novice, to an MMA-conditioned athlete, to a UFC fighter. My husband and son also train and compete in jiu-jitsu tournaments at least four times per year. CSW has shown them the skills, trained them hard, and conditioned them to win those tournament medals! I can say that CSW will always be our “Gym Family”.

Nicole, Chris, & Zander Rogers

I’ve been taking my sons (5 & 7 years old) to CSW for three months now and have been so happy with the decision. All the CSW staff and especially Coach Trent are awesome with the kids, teaching them the foundations of MMA, Jiu-Jitsu, and respect. My boys enjoy and appreciate every training session and highly look forward to “CSW Head Start Training”. It’s a family here, and everyone works together and supports one another. So glad we found you! I’ll be joining the adult class as a result of the outstanding work they have done with the kiddos and just seeing my boys being excited to train in a safe and supervised environment.Thank you, CSW!

CSW is a great gym, a warm, welcoming place to come and train. The staff is fantastic and friendly, with a nice variety of coaches and experiences who bring so much to each class.The coaches are so committed and disciplined and they teach social skills and graces in each class session. Inside it is clean, spacious, and open, with ample parking and plenty of room inside to roll, watch, or relax.We highly recommend this place to anyone interested in finding a great place to learn about wrestling, Jiu-Jitsu, and Boxing.
