G13 Colorado
The newest mat in the family, open since September 2026 in a brand new warehouse space right off the I-25 frontage road, serving Longmont, Mead, Firestone, Frederick and Erie. Adults, teens and kids from age 4, on the same G13 curriculum taught in North Carolina.
World class BJJ
in Longmont
The first G13 on the Colorado Front Range. The room sits right on the I-25 frontage road, a short drive from Mead, Firestone, Frederick, Dacono, Erie and Berthoud, and it runs the curriculum you find in Cary: fundamentals for people starting from zero, advanced, no-gi, a competition team and kids from age four. The weekly schedule and the free class sign up live on their own site.
