Peter G. Steinherz, MD

When a child needs specialized blood care, the city’s pediatric hematologists become the quiet backbone of a family’s routine. Peter G. Steinherz, MD offers that expertise on the Upper East Side, where the neighborhood’s mix of long-time residents and new arrivals keeps the demand steady for precise, gentle treatment of blood disorders and cancers. The practice sits at 1275 York Ave, New York, NY 10065, a stretch of avenue lined with medical offices that feel more like a campus than a commercial strip.

What sets this specialty apart is its narrow lens—focusing on conditions like sickle cell disease, hemophilia, and childhood leukemias—while still keeping the child’s daily life in view. Parents often arrive with questions about school accommodations, sports restrictions, or how to explain a diagnosis to classmates; the answers here are tailored to each case. The building itself is easy to spot from the sidewalk, with its glass entrance reflecting the trees along York Avenue.

Appointments tend to run longer than a typical check-up, giving families time to absorb updates without feeling rushed. A quick call to (212) 639-7951 will confirm availability and next steps. The office handles referrals from primary pediatricians across the borough, so even if you’re coming from Brooklyn or Queens, the process stays streamlined.
