Dr. Jon O. Marks, MD

Gramercy’s quiet side streets hold more than brownstones and corner bakeries. Among them is Dr. Jon O. Marks, MD, a urology practice serving the neighborhood since the early 2000s. Specialists here handle everything from routine prostate exams to more complex procedures like vasectomies and kidney-stone management. The field itself demands precision, and local patients often seek out practitioners who can balance medical expertise with clear communication.

You’ll find the office at 201 E 19th St, New York, NY 10003, just steps from the bustle of Union Square. The building blends into the block, its discreet signage matching the understated tone of the area. Urologists in dense urban pockets like this one tend to see a steady stream of referrals, given the concentration of primary-care doctors and walk-in clinics nearby. Common visits include urinary-tract infections, erectile dysfunction, and bladder-control issues—conditions that rarely make small talk but frequently shape daily life.

Those needing an appointment can reach the front desk at (212) 673-7300. The phone line connects directly to the scheduling team, who typically offer same-week slots for urgent concerns. While the practice doesn’t advertise weekend hours, weekday availability stretches from early morning through late afternoon, accommodating work schedules that don’t align with traditional 9-to-5 blocks. A map pinpoints the exact location for anyone navigating the one-way streets and construction detours that define this part of Manhattan.

Directions can be pulled up here. The practice sits on a stretch of 19th Street where delivery trucks double-park and pedestrians weave between scaffolding. It’s a slice of the city where medical care feels both essential and unassuming—no grand marquee, just a door that opens to a waiting list of neighbors.
