Joe Barth, Jr at the Hit Doctor in Mt. Laurel is a possibility for catching lessons in South Jersey. My kid has been lucky enough to sit in on a few of his sessions with college catchers - he’s a great teacher (his hitting instruction is also very good).
Eventually the Hit Doctor will put out their January-February player-development-program (PDP) schedule; in the fall they had Chris Widger running their catcher development sessions.
