Meet The Owners
Rodrigo and Ashlinn Gil-Samaniego are the owners and operators of 520 Boxing Gym. A boxing gym and nonprofit built to serve Tucson’s youth.
A Gym With a Purpose
520 Boxing was created to be a safe, positive space where young people can learn the discipline and skill of boxing while building confidence, respect, and resilience.
The focus is on supporting youth — especially those from underprivileged communities — by giving them structure, mentorship, and a place to belong.
More Than Training
Through structured training, community outreach, and leadership, boxing becomes more than a workout. It becomes a tool to keep kids active, focused, and inspired, while giving back to Tucson and investing in its future.
Rooted in Family
Rodrigo and Ashlinn are proud parents of two up-and-coming USA amateur boxers, which fuels their passion for mentorship and youth development both inside and outside the gym.
