New York magazine’s 2013 list of the metropolitan region’s top doctors includes more than four dozen of the physicians of Yale Medical Group (YMG), the medical school’s faculty practice. This year, the magazine named 49 YMG physicians in the magazine’s annual “Best Doctors” issue.

Castle Connolly Medical Ltd., a New York City research and information firm, determines the rankings via a regional peer-review survey that asks thousands of licensed physicians to nominate the physicians who, in their judgment, are the best in their field and related fields. The list is based on the annual Top Doctors New York Metro Area guidebook.

According to the company, the annual New York guidebook lists the top 10 percent of the metro area’s physicians. New York magazine’s list is more selective—the top quarter of the top 10 percent. This year, the magazine featured a total of 1,198 physicians.

“Yale physicians are simply world-class,” says Paul Taheri, M.D., M.B.A., deputy dean for clinical affairs and chief executive officer of YMG. “We recruit and retain physicians who have superlative training, educate future leaders, and support research innovations. The fact that 49 of our physicians were identified reflects our strength in a region with many academic medical centers.”
