If your seeking a speak pathologist, I would highly recommend a speech therapist who is of the same language or type of language as yourself or child.
So I am happy to inform expat westerners now have available an native Enghlish speaker who is fully quailified speech therapist in Chiang Mai.
Practice services available in English)
