I trained with Tim back in my old days. I was a pretty good shooter to begin with but he had me shooting over 50% from 3 in real games by the time he was done with me. He was truly an amazing coach; 15+ years later I still use some of the physical tools he gave me (though they've nearly fallen apart after all this time lol).
I don't live in the area anymore and have lost contact with him, but I feel like I remember hearing he had gone through some physical and mental health issues.
I know some of his shooting philosophies are considered outdated these days, but his stuff works amazingly well.
