The Speech-Language Pathologist at Mark Twain evaluates and serves children with communication delays and disorders. The two main areas are speech and language. The area of speech includes articulation errors (Do most people understand your child?), stuttering and voice problems . The language area includes vocabulary, grammar and ability to use language to communicate ideas and express their thoughts. If you, as a parent of a Mark Twain student, have a concern about your child's speech, language use or hearing, please contact your child's teacher or contact the speech pathologist through the office.
