People who stutter (PWS) develop fear and avoidance habits.  Unless we know how to help a pws with reducing fear and anxiety, we are not providing holistic therapy.  An embarrassing moment of stuttering or avoiding talking is "stored to the hard drive"-  it is consolidated, and it can be reconsolidated later.   You can actually feel an old memory in your soma! As Starkweather and Givens write, stuttering is a variant of PTSD (see below).   Anxiety and fear is the biggest obstacle for pws and graduate programs don't train students in CBT.  Time-Line therapy is special sauce in providing CBT for pws.  Disclosure and acceptance are essential but they take a long time.  What if you could run an antivirus scan in your brain and quarantine files of toxic memories, beliefs, and malware thoughts?  Caveat: as the wikipedia article states, you must be skilled in the delivery of this therapy.
