Our whole family loves Sigma! ALL of the instructors (Sensei Matt, Manny, Chris and Tim) are great with kids. All of the instructors have their own individual style, but I am consistently impressed that they are always patient, fun, funny, and engaging. Aside from keeping our kids physically active, I appreciate that they teach important concepts like discipline, gratitude and humility. Our 5 year olds love going to their martial arts class. There is also nice comfortable seating and wifi for parents to use while waiting for kids! I also love that these instructors are great with adults. I have never done kickboxing before but started kickboxing after seeing how great Sigma is with our kids. I appreciate that the instructors strike the perfect balance of encouraging and challenging. The adult classes have folks of all different skill levels, and they engage and coach each person according to their skill level.

My son (7 years old) has been in the aftercare program at Sigma since the start of the 2nd grade and absolutely loves it. He says going to Sigma is the best part of the new school year. The night after his first class, he put on his uniform back on and showed us everything he learned. He's fully engaged and committed it's so cute. It's remarkable the breadth and progress of skills he's learned over the past couple of months. The senseis make each class fun, lots of giggles can be heard from the waiting area. 10/10

I'm so glad I found Sigma Martial Arts & Fitness. I've tried several other martial arts schools, but none were as welcoming, friendly, and willing to work with my personal skill level and needs as Sigma. And the membership rates are quite reasonable--much more affordable than a gym membership. If you're thinking of giving martial arts a try, or if you already have experience, try out a class at Sigma. You'll be glad you did!

I’ve been training Jiu Jitsu at Sigma for almost a year now, and it’s been an amazing experience! The instructors are incredibly knowledgeable, supportive, and push you to reach your personal best. The classes are challenging yet fun, and the gym has a great atmosphere that motivates me every time I walk in. Whether you’re a beginner or experienced, this place is perfect for building strength, confidence, and skill. Highly recommend it!
