As someone who has given many presentations all throughout college, it helps to be up front about your stutter so that people have a chance to understand beforehand. I usually started most presentations with somewhat of a disclaimer. That being said, if you’re authentic and do your best, most people will be very supportive and you’ll probably make many more friends than you thought you would. You’re going to be fine, and you’ll feel SO good when the introductions are over. You got this!
