Has anyone had any success with a Speech Therapist/Pathologist

Has anyone had any success with a Speech Therapist/Pathologist I am very uneducated about my stutter, I became aware of it in 7th grade(I don't know if I had it before that and just didn't notice or if it onset at that age) I think its a motor issue, because I can fully imagine the words I am going to say, I have them planned out, but my mouth just can't make it work. An analogy for it is my mouth is a train that goes along the tracks, my brain is laying down the tracks(thinking about the words I'm go to say) and the suddenly the train just stops but the tracks continue to be laid down I don't know if this information has been useful in identifying what kind of stutter i had or if a speech therpaist would help me
