TIG welding courses.

Hi, My name is Eli and I am from Anaheim, CA and I am wondering if anyone could point me in the right direction as far as a TIG welding course of some kind that i would be able to take to learn as much as I can about this. I know a little, but dont feel its enough nor do I have much experience if any. I can MIG, but that's not what i am looking to do. Any Help with courses or anything would be much appreciated. Thank You
