What Our Customers Say About Us

I’ve been going to STC for about 3 months now, and can say this is one of the best decisions of my life! I have never pushed myself the way Brad will push you to your full potential. Not only are you boxing, but you’re also getting a full body crazy workout. Would absolutely recommend giving STC boxing & fitness a try, amazing gym with amazing and encouraging people.

Simon Hailu

I cannot say enough good things about STC Boxing & Fitness. In just two months, I can already feel myself getting stronger and my body changing. Brad, Kimbo, LeRoy and Danielle are not only excellent, knowledgeable instructors, but they are also great people. I appreciate that they take the time to help each student and address individual needs. No class is ever the same and I have learned so much in the short time I have been here. I am really excited that I have found something that I enjoy so much. By far, it is one of the best decisions I have made on my health journey. Thank you, STC!

The workouts never get old and better yet, never get any easier. The coaches there are great and you really feel a sense of camaraderie there. Would definitely recommend!
