Minute. Have you researched Dr.Gerald Maguire? There are many reasons that I suggest this. Primarily because he is a world-renowned physician who stutters. In his case it's genetic. There's much more to know about his research. His credentials are stellar. Like you, my stutter is physiological. I have zero social anxiety. I'd like to chat although I realize your time constraint. Would you consider chatting? I'm an older female, who stuttered since early childhood but I've become much more fluent in these past 10 years. Best
