★ 5★ 4★ 3★ 2★ 1My son has been coming here since April and we couldn’t be happier with the experience. Master Ben & master Williams are incredibly knowledgeable, patient, and motivating. Not only is he learning valuable self-defense and discipline, but his confidence and focus have improved so much. It’s a supportive environment that pushes him to be his best. Highly recommend this dojo!!
July 30 · Anastaisia AcevedoWhen my granddaughter said she was having her 7th birthday party here, I'll admit I was sure most of the kids wouldn't participate and the party would end up a bust. I'll also admit that I couldn't have been more wrong.The instructor kept the kids engaged and motivated the entire two hours. The games he played with them were educational and fun but he didn't let any of them win just for the sake of winning. He was encouraging, professional, personable, and the kids had a great time.If you're looking for something different to do for a child's birthday party, hands down this is one of the best experiences I've ever witnessed.
October 06 · Kimberly MegargelGreat dojo for all ages! Their system is easy to learn, practical, and teaches lifelong self-defense skills. The instructors make it fun while building confidence and discipline. Highly recommend.
August 22 · Jeff SalmMy son really enjoys coming here the instructors are very personable. The instructors really take the time to get to know the kids and families, especially during events! It’s a great environment and overall wonderful experience learning martial arts here
July 30 · Luke MoralesWe have been participating in online classes. Master LaMasters is an excellent and very patient teacher explaining moves so that anyone can understand them. His teaching pace allows for all participants to be successful. I highly recommend!
