Junnie Mark-Kobashi, M.D.

After-hours scares don’t always wait for the ER. Junnie Mark-Kobashi, M.D. handles the kind of urgent care that can’t be scheduled—sudden fevers, deep cuts, or that persistent cough that won’t quit. The office sits at 170 William St, New York, NY 10038, a block where the Financial District’s glass towers give way to older brick low-rises, and the sidewalks hum with a mix of late-night shift workers and early commuters.

Emergency care here isn’t about the drama of TV shows. It’s the quiet efficiency of stitching up a kitchen knife slip at midnight or diagnosing a mystery rash before the subway ride home. The neighborhood’s pulse is steady, not frantic, and the clinic fits right in—no fanfare, just a door you walk through when the urgent-care centers have closed their shutters. No appointment needed, but timing matters.

They don’t answer questions about wait times over the phone, so showing up is the only way to know. Call (212) 312-5070 if you need to confirm they’re still open before you trek down. For directions, pull up the map: 170 William St.
