Silvia Contreras, NP

Upper Manhattan internists don’t cluster on every corner. Silvia Contreras, NP keeps an office on the eighth floor of 17 E 102nd St, a block where the sidewalk hums with hospital traffic and the occasional halal cart.

Primary care in this stretch of East Harlem means threading between the big medical centers and the smaller practices that still answer their own phones. A restroom is available, a detail that can matter when the nearest public option is three avenues away.

Directions are easiest if you treat the building as a satellite of Mount Sinai; the same elevators serve both. When the automated system asks for a callback number, give (212) 241-7270—the line rings to a human, not a menu.

Map the route ahead of time: here. The neighborhood’s pulse is steady, unhurried, the kind of place where a nurse practitioner’s name stays on the door for years.
