Grampas Boxing Gym is a very pleasant and professional place to practice your favorite sport: boxing. They have highly trained and friendly staff. I trained my sons, Miguel Angel Rosales and Samuel Rosales Tabares, there and I truly recommend this place.

We enrolled our son first, then our daughter two weeks later and we’ve been extremely happy ever since. The gym has great energy, and everyone’s been welcoming. Coach Lexy, who works with our daughter, has been amazing. She’s supportive, motivating, and really knows how to connect with young athletes.

Based on a friend’s recommendation, I enrolled my son in boxing classes and have been extremely pleased with the experience. Coach Angel is excellent, providing both skillful instruction and strong leadership. The program is well-structured, and we are very happy with our decision.
