I have met Jake Sullivan numerous times. Personally, I found him to be a solid teacher.
My experiences was watching him work out with some high school kids, girs and boys. I don't claim to be a close friend with him, or know him beyond my handfull of dealings with him, but I was always impressed with his passion and intensity.
I know first hand that a lot of kids he has helped and parents of those kids respect the hell out of him. I do know a number of them very well.
Stories are like bread no matter how thin you slice them there are always 2 sides. After reading this and knowing some of the kids I do, I would venture to suggest that Jake is not the monster some are making him out to be, some of the kids and parents probably have or had different expectations and that there is probably some right and wrong on both sides of this issue.
