About the Upstate Grappling Club

At The Upstate Grappling Club, we believe that grappling is more than just a sport—it’s a journey of personal growth, discipline, and community. While the gym was initially established in 2023, we’ve gone through some major changes in leadership in 2025 to build back the structure needed. Under new leadership, we’re committed to fostering an environment where every member feels valued, challenged, and inspired.

Centrally located in Halfmoon, NY, The Upstate Grappling Club is dedicated to making a positive impact in the lives of both adults and children through martial arts, education, and coaching. Just 1 mile from interstate 87, we strive to provide a welcoming space for all students and skill levels.
