Public speaking groups for stutters?

Public speaking groups for stutters? Hello! I was just wondering if there are any online groups that deal with public speaking for stutterers. I accepted a job today where I will have to give a few presentations. I haven't done a presentation in around 2 years. I have a very mild stutter in my day-to-day life but during presentations, I would normally get super nervous and stutter a lot. I want to be able to practice giving presentations and become more fluent. If you have any tips for stuttering less during presentations, any advice would also be appreciated!
