Our Story
Built for Pittsburg. Trusted across East County.
501(c)(3) nonprofit
Lion's Den Boxing Gym was built to give Pittsburg something real: a boxing gym that serves the community and takes the work seriously. It is a place where kids can build discipline, teens can find direction, and adults can train in a room that feels honest from the minute they walk in.
What makes Lion's Den different from every other boxing or fitness gym around here is that it can do both jobs at once. It is a safe space for families and young athletes, but it is also home to serious fighters, including Amari Jones, now 16-0 with 14 knockouts and signed to Golden Boy.
As a 501(c)(3) nonprofit, Lions Den is built to serve more than just competitors. The gym creates a safe, structured place for youth development, community support, and real mentorship in Pittsburg.
