Solid teaching and very family friendly! Sensei Matt is understanding of military schedules and offers flexible pricing options. The Mighty Ninja program is amazing and my son loved every class he was able to attend! He really enjoyed learning from the older kids who were assisting during the workouts. Just an amazing place overall and highly recommend as they have something to offer for every member of the family!

Very family friendly and accommodating on my work schedules. As a single working mom I cant just do Monday through Friday at 2pm or something along those lines. People that work 9-5 jobs would never be able to take their kids. .. I'm very Happy to have found this place for my 4yr old daughter. Love the atmosphere and structure.

We are a Marine family and have been a part of this dojo for about four to five years now. Key Martial Arts has become our second home and has helped my daughter immensely in her confidence and leadership skills! She started as a yellow belt and is now a junior black belt. She also participates on Sensei Matt's leadership (STORM) team.
Sensei Matt and his wife are kind, knowledgeable and the kids have fun in their classes. Also, if kids are struggling outside of the dojo, Sensei provides guidance and support. We love this place!

I initially was looking for a sport for my 6 year old son as we had tried baseball and soccer with no success. We went in for our free trial day and I walked out with not only registering my 6 year old, but also my 8 year old daughter and 4 year old son. Key Martial Arts has been a wonderful environment for all of my children. I can't say enough what a great job they do. We have been there now for almost a year and I have to say we are so privileged to have found them!!!
