I second the Callier Center - It's on the UTD campus in Richardson. They have a lot of options for you!! Private Speech Therapy, SMile, STARS (Articulation Program), and a Preschool Program. There are others on their website but these I think are probably more of what you might need. Please feel free to email me with any questions. My son is in Private Speech Therapy with Berkley Williams. (She is great!!!)
