I highly recommend the Dave McGuire Program! Also reading Redefining Stuttering by John Harrison. You can find a free link to the book if you google search it. And as others have recommended, be vulnerable. Tell others you stutter when you meet them. This will decrease tension. Also, stutter on purpose around others to desensitize yourself to stuttering. And you can even tell your employer how your challenge with stuttering has actually made you a stronger person.
