Speech Therapy Specialists

The therapists assist families in feeding their infants and in techniques for post-surgery feeding. The speech pathologist evaluates each child prior to surgery to assess feeding and language. The therapist will also communicate with a therapist from the patient’s hometown to address goals and how to achieve them post tongue reduction.
