What to Expect at Your First Appointment

Patients of the VPI & Voice Center are first evaluated by our pediatric speech pathologist, Yvonne Knapp, who performs a thorough speech evaluation, including nasometry, over the course of approximately one hour.

Patients are then evaluated for approximately 30 minutes by one of our pediatric otolaryngologists, Vikash Modi or Alison Maresh, who specialize in velopharyngeal dysfunction.

Finally, our team performs a nasopharyngoscopy to assess your child’s velopharyngeal function. They will then meet with you and devise a personalized treatment plan to address your child’s specific needs.   

A full report documenting our findings and recommendations will be sent to your pediatrician and your primary speech pathologist.
