I suggest SLP Stephan. He’s a speech therapist and stutterer with a self study therapy program. He has managed his stuttering very well. It’s still there (I think it’s rare to be “cured,” ! but his disfluencies are brief. One thing I like about the program is he has videos that model various approaches. The other thing I recommend HIGHLY is listening to the Stuttering Foundation podcast: Why Stuttering Occurs—The Role of Cognitive Conflict and Control. It’s from August 9 2022 Dr Usler.
