Good luck. I would say the majority of teaching in Middle TN is HE. Hit after Hit in Donelson has recently added Katie Burkhart-Gooch from Arizona State University. My guess is that she probably does not teach HE, but I have never talked to her to find out. Their prices are at the high end of what you will pay in the area. Good luck.
We scheduled an appointment with her but some family issues have risen for her and she is not doing lessons right now. Trying to find someone along the same lines as her.
I have done several clinics with Brandon Carr. He teaches I/R, Brush Interference, Arm Whip, lots of good stuff. Just opened a new facility in Knoxville....Brandon has worked with every level pitcher and has some real outstanding students. He knows what to teach to get a pitcher to the next level.....if you're anywhere near Knoxville I'd highly suggest you check him out. If you need hitting lessons they have some high level instructors there also.
