I took lessons with Chad Martin and he's by far the best drum teacher I've had (I've had two other instructors). He has a laid back teaching style, but he doesn't let you slack. Chad is personable and helpful, but at the same time pushes you to help achieve your goals.
I knew Chad because he was in a band project with friends of mine. He knows his stuff. He has toured all over and played with the best musicians in Phoenix. This guy has been around the Valley for a while, but he's still pretty bad-A! You know that one guy who thinks he's cool because he's in a band? That's not Chad. Chad is like the Chuck Norris of drummers. Chad doesn't play music, he is music.
He also teaches at the School of Rock, but I took private lessons because we both live in the Arcadia area. SOR is cool for kids, but not for working folk.
Like I said, he's super personable. Total family guy.
