Rebecca Z. Callahan, MSN

Primary care visits, annual check-ups, and acute illness treatment all start with Rebecca Z. Callahan, MSN. The practice sits two blocks from the 4/5/6 at 86th Street, a short walk if you’re coming from the subway or from one of the prewar co-ops that line the block. Flu shots, chronic disease management, and women’s health services round out the offerings, all handled in the same office.

Find the entrance at 25 East 86th Street, between Madison and Fifth. The six-story limestone building has a discreet brass plaque, the kind that blends into the Upper East Side’s quiet elegance. Foot traffic stays steady through the morning rush, and there’s always a bench on the corner if you need a moment before stepping inside.

To set an appointment or confirm availability, dial (609) 468-3670 and a member of the team will guide you through next steps. No referral paperwork waits on arrival, and the front desk keeps the flow moving whether you arrive five minutes early or right on time.

Once you’re ready to head over, pull up the map to plot the quickest route from wherever you are—traffic on East 86th rarely slows to a crawl, and the walk from the 6 train is flat and shaded by sycamores.
