What Our Clients Are Saying

"As the father of two boys who played for Mesa from 3rd grade through High School, I can tell you our experience was awesome! Both our boys ended up playing Division I lacrosse. I truly credit Mesa for most of their success. The coaching is 2nd to none and the friendships we all made will last a lifetime. We played in the top events and had tremendous exposure to college coaches at every level and location. The Mesa staff provided insight and advice throughout the entire recruiting process. They excelled at multiple levels including fundamental coaching, team concepts, individual technique, and recruitment counseling. The staff has deep contacts in the college coaching ranks and has literally seen it all. I highly recommend Mesa for any family that wants to have the best club experience in the country. The success of their players speaks volumes and my boys, who are now men, cherished every minute of the experience." Enrique Hervada
