Any professors or TAs here?

Any professors or TAs here? I'm considering TAing next semester and the only thing preventing me from doing it is my stutter. I know the course material extremely well and I have several friends that are currently TAs for this class. I just know I'm going to stutter so much and it's really psyching me out. I can barely introduce myself to another person, so going in front of a class is a thought that kills me. Does anyone else here teach and have tips to overcome this feeling?
