Johanna Contreras, MD

Across Union Square and the surrounding neighborhoods, Johanna Contreras, MD fills a specific role most cardiologists handle with paperwork instead of practice. Board certification in cardiovascular disease and internal medicine means advanced rhythm management comes alongside routine check-ups and lipid analysis. She doesn’t just hand over a prescription; lipid-lowering therapy and post-procedure monitoring follow through until the numbers settle. Exercise stress testing, nuclear cardiology imaging, and echocardiograms get scheduled without spinning through a revolving door of third-party labs when she coordinates the follow-up herself.

Her office occupies the second floor at 10 Union Sq E 2nd Fl, New York, NY 10003, tucked above the weekday foot traffic but close enough to the subway for quick exits after appointments. A short stroll east crosses Park Avenue South, and the block stays lively even after clinics close. For a route that avoids circling blocks, pull up the directions: just north of 14th Street on Union Square East. Call with questions when the screen feels less useful than the voice on the line: (212) 523-2400.
