Alexander Phan, M.D.

Alexander Phan, M.D. operates a diagnostic center in Manhattan’s western fringe, where the grid meets the Hudson. The practice occupies a stretch of 35th Street better known for its industrial lofts and wholesale suppliers than medical offices. Diagnostic work here covers the expected spectrum—bloodwork, imaging referrals, routine screenings—without the clinic-chain trappings. Patients arrive for lab orders or follow-ups, then move on; no frills, just the baseline mechanics of healthcare.

This part of Midtown West still carries the faint hum of garment-district history, though the sidewalks now host more food delivery bikes than fabric rolls. The address, 504 W 35th St, New York, NY 10001, sits a few blocks from Penn Station’s chaos but feels removed from it. Diagnostic centers in this area tend to serve two audiences: locals who’ve lived here long enough to remember the neighborhood’s shifts, and commuters squeezing in appointments between trains. Neither group lingers.

Booking a visit means a call to (888) 922-2257, where the process skews functional over fussy. No online portal theatrics, no chatbot runarounds—just a direct line for scheduling or clarifying what a particular test entails. The approach mirrors the neighborhood’s utilitarian streak. Even the map pin drops into a block that’s more about efficiency than aesthetics, with the directions threading through a mix of pre-war buildings and newer, glass-fronted replacements.

Afternoon light here slants differently than in the rest of Manhattan, filtered through the elevated train tracks and the occasional gap between warehouses. The diagnostic center doesn’t try to compete with that light—or with the delis and dollar stores that outnumber it on the block. It’s a place for blood draws and paperwork, not small talk. The sidewalks outside stay busy, but the foot traffic isn’t the kind that stops to window-shop.
