Another problem that some of the top coaches/clinicians have with him is how they'll show up to his camp for a couple of sessions, and then he uses their pictures & names for years and years after that, making it look like they still work his camps.
Check out the summer camp brochure and the clinicians pictured. Then call the office and ask which clinicians will be at which camps. The "non-answer" answer you'll get? "Every camp location will have a top notch staff."
