Do you need therapy for mild stuttering?

Do you need therapy for mild stuttering? Hello everyone, So I have a mild stutter that comes and goes. It hasn't impacted me that much. I have had job interviews and did presentations at work without much trouble although I stuttered a work presentation last week which was horrible. I went to a speech therapy and she said my stutter was mild enough that I didn't need regular speech therapy. She gave me a list of exercises to do that have helped. My parents disagreed with the therapist's assessment and said she was quack even though neither of them are a speech therapist. My stepmother insists without evidence that stuttering can be completely cured. They are nagging me to go to a speech therapist and said my stuttering is horrible. Thang God I live on my own or else they would drive me crazy.
