My son has really enjoyed his boxing classes at JOC boxing! He had taken a class at another boxing facility and thought it was really boring. He decided to try a class with Mark and absolutely loved it! Been going for 6 months now and wants to stick with it awhile!

I’ve been training with Mark for a few months now and have had really good workouts. Much different than just going to the gym and lifting. Mark knows what he’s talking about, is thorough and prioritizes in areas like discipline, footwork, balance and hand/eye coordination. I’d recommend Mark to anyone looking to learn more about boxing and is interested in a strong workout.

I started working with Mark earlier this year. Due to a serious back injury, I wasn't able to do much in the way of physical activity for the last several years. My conditioning lacked and was far from the shape I was once in. I explained my injury to Mark and he assured me he could design a training program that would both challenge me, while still being mindful of my injury history. He did just that! He made me feel very comfortable getting back into a workout routine. I eased into it and with each session, I felt like I was starting to get back to my old self. He is a great instructor. All of his equipment is clean and modern. He takes his time with you. Coming from someone that was well out of shape, he is also extremely patient with you. I couldn't ask for a better trainer! Do yourself a favor and book a session. You won't regret it!!

Even during the toughest times Mark has kept me focused and goal oriented. He has been my biggest fan throughout this transformation process. If I could give more than 5 stars, I would!!!

Having Mark as a Boxing trainer was one of the best things I’ve recently done for myself! The training sessions have taken me to a completely new level of fitness and my cardio is getting better with each session l complete. lf you want to learn how to box and get all the basics that come with it: foot work, head placement, body positioning, learning how to breathe correctly while throwing and defending or if you just want to get your body right, then JOC Boxing is the place!

Last year I started training with Mark (JOC Boxing1), and I couldn't be happier with my experience. Mark's knowledge of boxing technique is exceptional—he himself was trained by an Olympic boxer—and he has a real talent for coaching. His expertise was evident from the first session, and he knows exactly how to impart his knowledge effectively to students of all ages, shapes, and sizes. His master's degree in education certainly helps in that regard.

Mark adapts his coaching style to fit each individual's needs, making sure everyone feels comfortable and capable, regardless of their skill level. His ability to break down complex footwork and other techniques into understandable steps is remarkable (and much appreciated!).

Mark's sessions are tough but fair, pushing you while ensuring that you're learning and improving. His sense of humor adds a fun element to the workouts, making even the most challenging sessions enjoyable. He strikes a balance between being a disciplined coach and a personable mentor.

Overall, training with Mark has been a highly enjoyable experience. His dedication to his students and passion for boxing make him an outstanding coach. Whether you're a beginner or an experienced boxer looking to improve your skills and enjoy your training, I highly recommend Mark.
