There are a few every summer it just depends on what player or team your looking to learn from. Every team has different styles of play and they teach you the basics and advanced techniques based off of what brought them success. You might have to do a little traveling though man. Upton 187 is a few hours north and Damage is down in Florida. You also have a few individual pros who play out of PAP and myself who plays out of OXCC. Both fields are located here in MD, just opposite ends. Seattle Thunder will be doing a clinic here in Maryland at the end of spring!
Just keep your eyes open!
