Coach Nick at Sweet Science Boxing is the real deal. His attention to detail, patience, and ability to break things down make every session valuable whether you’re a beginner or more advanced. He pushes you to get better while keeping the environment positive and motivating. You can tell he genuinely cares about his fighters’ growth inside and outside the gym. Training with him has improved my technique, conditioning, and confidence. Highly recommend Sweet Science and Coach Nick to anyone serious about leveling up their boxing.

Coach Nick does a great job. My teenage son goes to personal training sessions at Sweet Science and is learning boxing fundamentals, and making great progress. I highly recommend Sweet Science.

Coach Nick is phenomenal in every way. He was so kind and welcoming. I was very intimidated and self conscious going into my first lesson and he made me feel completely comfortable and relaxed. He knows his stuff top to bottom and inside and out, but stays so relatable, encouraging, and kind. If anyone is questioning if this gym could be right for you, don’t. This is your sign to join!! You won’t regret it.
