Anyone know an awesome mental health provider who specializes in treating adolescents who stutter?

Anyone know an awesome mental health provider who specializes in treating adolescents who stutter? I'm an SLP and I have a teenage client who stutters. I won't go into too much detail, but their mental health is the main priority right now and it's beyond my scope. I know plenty of great metal health providers to refer him to, but I worry that a provider without experience in this area may be dismissive of his feelings toward his stutter. To people who don't stutter, I can see them thinking his stutter is *"not that bad"*, but to him it's life shattering. Location doesn't matter as his family is willing to do telehealth/private pay.
