Calling speech therapist

Calling speech therapist I am a speech therapist looking for resources on how to work with clients who have situational stuttering. I has been difficulty observing my clients stuttering as he has made progress to the point that stuttering in individual is minimal, but situations like public speaking or when there is greater than 10 people continues to be challenging. To re-create these situations aren't always easy to practice nor to observe. Any help or discussion would be great. Thank you!
