Testimonials
I’ve been boxing for over 30 years and for the last 8 years I’ve had the great pleasure of being a member of MK Boxing. This summer I won the Ringside 2015 World Championship in the Masters Division and MK Boxing helped me achieve that – I couldn’t have done it without them. Owner Mike Knox, instructor Justin Piper and fellow member Christian Berrios have sparred with me and helped me train for all of my tournaments. Whether you want to compete or just get in shape there are trainers in all Martial Arts forms to help you meet and exceed your goals. Thank you Mike and the team at MK Boxing for all the great training.
It’s so refreshing to be a part of MK Boxing. From the members to the instructors, the environment at MK Boxing is inviting, encouraging and FUN! Every class is challenging and different. The instructors are not only experts in their respective disciplines, but they are passionate about developing everyone’s skills. Where else can you get such a variety of offerings in an enjoyable environment? Other gyms pale in comparison. Thank you for the best workout that I will ever love!
