I'm not a physician, but i'm about to get my PhD. I do a lot of lecturing and talking to people at my university. You've already received some good advice. I only want to add one thing: There are no data that even remotely suggests that stuttering is associated with decreases in cognitive ability or job performance. Stuttering cannot limit your professional dreams or make you a bad physician. Your reaction to stuttering can cause you to limit your dreams. Being unethical and sloppy with the practice of medicine can make you a bad physician. Stuttering is an obstacle, yes. But it is clearly not an insurmountable obstacle. You're already doing it. Just keep doing what you're doing. As far as tricks and tips, self-disclosure can be a powerful tool. If you feel it's appropriate simply disclose that you stutter. Don't be defensive or apologetic. A physician with a hearing impairment might self disclose and indicate she/he may ask for a repeat of what was said. You stutter, and sometimes words get stuck and it's okay for someone to ask you to repeat yourself if they missed what you said. If you don't treat it like a big deal most people will follow your lead.
