Pitching Coach in Chicago Suburbs

I am looking for a high-level pitching coach for my 11 year old son in the western suburbs of Chicago (Oswego, Naperville, Plainfield, Bolingbrook, Joliet area preferably). Thanks!

I’d recommend Mark Sheehan - (630) 946-7179

You can google “mark Sheehan baseball” to find out more about Mark but here is some info:

“Mark was appointed by Coach House as the National Director of the NPA in 2015 and served in that role through 2017 before branching out on his own with Evolution Athletics Baseball. The Collegiate Baseball News awarded Sheehan the 2014 Teaching Professional of the Year Award in Orlando at the ABCA Annual Convention.”

Mark is in Naperville.

Thanks! Has anyone heard of Chris Pack, Corey Kimes or Lou Simios? All three are pitching instructors at the Baseball Institute out of Mokena and Romeoville, Illinois.
