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".

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!

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.

I reached out to Donny, over a decade ago, wanting to learn self-defense. I was dealing with constant harassment from unsavory neighbors. And I knew it would eventually escalate to violence, despite me always ignoring them and walking away. If it were not for Donny, I would have been a victim. When it comes to fighting, Donny taught me everything I know. And I have used those skills on a handful of occasions.

When it came to training, Donny was always patient, kind, and calm with me. Not once was he ever mean or verbally abusive towards me. And believe me, I was hard to teach and took forever to learn how to throw a proper jab, cross, hook, uppercut, etc. In all honesty, throughout all the years I have known Donny, I have never heard him yell, or seen him angry.

If you are looking to learn self-defense, Donny Giron is the one you want to see. He will provide you with a high level of personal support and heartfelt understanding. I always felt seen and heard with Donny when I was dealing with my personal problems.

I am proud of my brother for making his wish come true and that is opening his own gym. He will do his best on helping his clients with fitness and training.
