Good luck! Just remember that no one will really care about your stutter. It really shouldn't have any impact on what you're doing or the value and reception of what you have to say. I work in the office of a manufacturing plant, and my role includes giving IT training to co-workers and answering the phone. It was hard at first (as a person with a moderate-severe stutter), but people seem to look past it as they would with any other personal challenge.
