I took a semester of it in college...years ago..LOL In my class was a woman who was going to get a degree in it at a different college in Ohio..but can't remember which one, I was thinking somewhere around Wilmington, OH, but not positive. Here is a link from the Ohio School for the Deaf that has a bunch of info on it, such as becoming an interpreter and also interpreter training programs...might be useful.
