Siyang Leng, MD

Hematology bridges the gap between routine bloodwork and specialized care for blood disorders. Siyang Leng, MD practices in Washington Heights, where the neighborhood’s mix of long-time residents and medical professionals creates steady demand for precise diagnostics. Blood cancers, clotting disorders, and anemia require a practitioner who interprets lab results with both clinical rigor and contextual awareness. The office operates from 161 Fort Washington Ave, New York, NY 10032, a building shared with other Columbia-affiliated specialists. Patients often arrive after referrals from primary care physicians or oncologists, seeking second opinions or ongoing management for chronic conditions like leukemia or sickle cell disease.

Beyond standard consultations, the practice handles bone-marrow evaluations, transfusion protocols, and coordination with infusion centers. Washington Heights’ transit access—via the A train and several bus lines—makes the location practical for patients traveling from Upper Manhattan or the Bronx. To schedule an appointment or confirm insurance participation, call (212) 305-5098. Directions and building entry details can be found on the map. Most visits begin with a review of recent lab trends rather than a physical exam, so bringing prior test results streamlines the process.
