Obviously Donnys career as an amateur and professional boxer speaks for its self. His genuine caring personality and how he works with my 2 sons(7&10) is really something SPECIAL!! Their confidence grows and grows. Donny Thank you. We love you!

This has the award for the best boxing gym in Adam’s county for a reason. I’ve been going to this gym for about 3 weeks now and I couldn’t be happier. Donny is the owner and coach here and he’s very friendly and easy to get along with. I felt at home the minute I stepped into the gym, I didn’t feel nervous or out of place. The members here are just as amazing! The first day I was there I had members as young as 10 trying to help me breathe more efficiently during rest times. I’m 32! Everyone here just wants to help and support everyone and it’s great. Donny keeps the gym very clean and even has a small boxing ring inside. If you’re looking for a place to learn to box, this is definitely the place! I wish I could give more stars than 5!

Coach Donny is the best. He taught my son the basics, proper technique, and my sons conditioning has greatly improved since coming hear early fall 2025. Before coming here I tried to contact other boxing gyms around Thornton, but I didn't get a response. I also didn't want to sign my son up for those bougie gyms where the entire group dance slaps a heavy bag with 18oz gloves while listening to 90s dance music. I wanted my son to learn to protect himself, work on his reflexes, have discipline, and have better conditioning. Coach Donny is truly a one of a kind and this is exactly what I expected from a real boxing gym. My son enjoys coming here and looks forward to it all the time. I see a young Naoya Inoue in the making, the next "Monster".

My son has been at DG Boxing for a few months and loves it. Donny is an incredibly patient coach and is constantly helping my 6 year old improve his skills. I highly recommend DG boxing for your kids to box. It is affordable pricing, flexible schedule and provides one on one training.
