I'm not sure if there is... But this coach says he is certified by Mlb....i have never heard of that... I have heard of Epstein certification that is Supposed to be very good and we'll respected... I'm thinking several different instructors have their own cert program?
I'm pretty sure mlb didnt even have hitting coaches until the late seventies
why don't you send a pm to pc, some think he may be martian lunar base aka mlb-certified.
