""I have trained all over the United States at some of the top Martial Art Gyms. Sim's has gave me a more broad perspective of Jiu-jitsu and a completely different outlook of the ground game. I would encourage this gym to anyone interested in Martial Arts." 
"The GRINDER" Chad Reiner (2xUFC Veteran)

"I've been doing Jiu-Jitsu for a while now and i've never seen anything like 10th Planet Jiu-Jitsu, Its truly a unique and comprehensive system that any Jiu-Jitsu practioner can benefit from"  -Gary Meek 5th Degree Black Belt, Rodrigo Vaghi Blue Belt, Krav Maga Certified Instructor

Finding and Joining SIMS Academy has been one of the best opportunities my Family could ever experience. The Staff at SIMS is extremely remarkable; they treat their members as family. The understanding, confidence, compassion, and thoroughness they teach with, are given to each and every one of the students of all ages. My son, Anthony, has been a member of SIMS Academy for close to a year now, and in this time he has been steadily growing and developing into a young man utilizing all of the Character Building Attributes that are taught. What he has learned, and shared at SIMS this past year will carry with him for the rest of his life. The goals and attributes that he is learning at SIMS are lessons he uses everyday to succeed in life. I could never thank them enough for all that they have done for all of us.

The Sanchez Family

My two children, ages 10 and 9, have been with S.I.M.S. for a little over a year. I looked long and hard for a dojo and teacher that would treat them with respect yet push them to find their self-confidence and discipline. My son is a cancer survivor and dreamed since he was 3 of "doing karate." As soon as he was cleared, I went looking for a dojo that would accept his needs yet not let him use them as an excuse not to succeed. I think Sensei Derek and Mrs. Gina have been absolutely wonderful to both of them. It's great because I also feel valued as a parent and supporter.

"What can I say about SIMS. Wow, they are like a family. My son (now 13 years old) has been with Sensei Derek and the school, since he was 2 ½ years old. If he could follow the leader, he could take classes. Logan has learned responsibility, respect, and discipline from day one. Now he is learning to be a roll model by teaching tiny tigers and introductory rank classes. Working hard and staying motivated has been instilled in all students. To include me, Logan’s mother. I also take adult classes. It is addicting and fun. Keep up the good work!!"

With consistency, time, and a new found confidence, I have lost over 60 pounds to date. And it doesn’t stop there. I now have a knowing that I am a whole person and I deserve to be the best Me that I can be. SIMS Martial Arts Academy has truly been my saving grace." - Libby C.

The Sims Dojo is a family dojo . . . we are one big supportive unit. Derek is a caring teacher who is patient and pushing all at the same time.  We kickboxing ladies have a ton of fun (Miss Gina always gets us rolling) and we cheer and push each other even when it feels we can’t go on.  No matter what age or belt level, there is always someone there who will help you in ju-jitsu when you just can’t quite get something.  We support each other not just during competitions and belt-testings, but also for life events and celebrations outside of the dojo. -  Abigail B.

I've lost over 50lbs and the difference between me and Jared from the Subway Diet is that i can kick his....

I've been to multiple gyms in the metro and can honestly say I've found a home at SIMS.
