Dr. Frank Nelson

Amsterdam Avenue runs a steady, unflashy course through Upper Manhattan, past brownstones and the occasional bodega. Behind its storefront awnings, Dr. Frank Nelson operates a gastroenterology practice that feels built into the rhythm of the block rather than pasted on top of it. The office sits at 1090 Amsterdam Ave, New York, NY 10025, where it anchors a stretch that’s long served locals needing routine screening, colonoscopy, or treatment for conditions like IBS and GERD.

The phone rings straight to the front desk: (212) 523-5900. They handle appointments for colon cancer screening, upper endoscopy, breath testing for H. pylori, and management of hepatitis C among other digestive issues. Whether you need routine screening or a focused work-up, the practice appears to move patients through efficiently without broadcast fanfare.
