I'm an accountant so I have to meet with clients and answer phone calls on a daily basis. My dad is one too and probably sees clients twice as much as I do. Sometimes the idea of giving a presentation to the office or something like that will make me nervous, but as you gain experience you'll learn little tricks about how to keep yourself fluent and/or feel less uncomfortable when you aren't so fluent (troublesome words/phrases to avoid, go to excuse,etc.). Some days you'd never know I stutter. Other days you might be able to tell. Only advice I can give is to focus on it as little as possible. If you don't think it's gonna be an issue, it probably won't be.
