Specialty Division Heads

At the Herman & Walter Samuelson Children's Hospital, we provide children with comprehensive medical care that keeps them safe and healthy.

Our reputation for excellence is based on the stellar care and compassion we bring to our patients. We get to know our patients by name, understanding each one’s fears and anxieties as well as what makes them laugh and smile.

Our dedicated specialty division heads include board-certified physicians, neonatologists and a hospitalist who all provide round-the-clock coverage. Each one will always take the time to listen to your questions, alleviate your concerns, and help you and your child in any way possible.
