Only went once and had a poor experience. I was brand new to boxing and told the trainer I was. It started out well and technique was the main focus. Then he had me sparring with a middle aged guy and I got knocked it the head a few times. Before this, I had even mentioned that I brought everything I needed but a mouthguard, which I had yet to purchase. I’m aware that I am capable of stating my needs (and should have in hindsight) but when there’s two older guys who are urging you to fight, it’s not easy to say no. Lastly, t... read more

I decided to look for boxing lessons to learn the basic mechanics of boxing and build a foundation of self-defense. Jameson is relentless when it comes to drilling the fundamentals. It’s not flashy or fast, but it’s incredibly effective. In boxing, there’s no place to hide - you’re forced to immediately confront your weaknesses and sharpen your strengths. After just one month, I’ve lost weight, gained strength, and enhanced my mental and emotional regulation. Jameson’s approach has already given me the confidence to sign up ... read more

1. The reason i decided to look for boxing or fighting techniques is because i always had a passion for martial arts, its not for no reason. but i always dreamed of becoming a professional boxer.

Where do I start? I've played many sports starting since before I can remember and never once had anyone in my corner nearly as inspired and dedicated to making me the best version of myself I can be like Jamie does. Honestly, working with him has been a truly life-altering experience for the better. Ever since the first day I met him, I can immediately tell he's as passionate about what he does as it gets and it shows in the results you'll see from working with him. A true professional at his craft. No BS, no excuses. Just ... read more
