Our Team

At The HSC Pediatric Center, our goal is to provide the best possible care for children and young adults with special health care needs. Every day, our clinicians work hand-in-hand to provide the children we serve with the most advanced rehabilitative and transitional care available in the region.

We have a team of pediatricians, pediatric nurse practitioners, nurses, physical therapists, occupational therapists, speech-language pathologists, respiratory therapists, dieticians, psychologists, social workers, case managers, recreational therapists, and child life specialists.

Pediatricians also staff the hospital 24 hours-a-day, 365 days-a-year, ensuring that a physician is always close at hand.

Our Relationship With Children’s National Health System

As a result of our close relationship with Children's National Health System, many hospitalized children are able to see medical specialists at The HSC Pediatric Center, without the need to travel from one hospital to the other. When a specialist visit is needed during an admission for a provider that does not see patients at our facility, we will coordinate the transportation for the medical visit. Providers from the following specialties regularly see patients at The HSC Pediatric Center:

  • Cardiology
  • Developmental Pediatrics
  • Gastroenterology
  • Infectious Diseases
  • Ophthalmology
  • Physical Medicine and Rehabilitation

If you have questions about our medical staff, please contact Sonia Prince, our medical staff administrator, at 202-635-6138.
