I am extremely honored and excited for the opportunity to lead the Chattahoochee High School Boy’s Lacrosse program. Chattahoochee is one of the original Georgia High School lacrosse programs with a rich lacrosse history and strong foundation for us to build upon. I see incredible potential with the current team and I’m highly motivated to revamp the Jr. Cougars program for long-term stability and success at the high school level. Go Hooch!
