Who

One of the top fertility doctors in New York, Rosenwaks heads up the Center for Reproductive Medicine and Infertility at New York-Presbyterian/Weill Cornell.

Backstory

A reproductive endocrinologist by training, Israeli-born Rosenwaks has been researching fertility since the early '80s. In 1988, he arrived in New York following a stint at the Jones Institute for Reproductive Medicine in Virginia, where the first baby created via in-vitro fertilization was born. Since then, he's become a fertility pioneer, credited with founding one of the first egg donor programs in the U.S. In between treating patients at his Upper East Side clinic, the Center for Reproductive Medicine and Infertility, he also teaches classes in obstetrics at Cornell's medical school.

Of note

Rosenwaks' fertility clinic is one of New York's busiest. His center oversees 2,200 IVF cycles each year (which can cost $10,000 a piece) and has a staff of over 100 people. With a 50-percent live birth rate, he also has one of the best track records in the city, which has attracted patients from around the country and world. One famous face who has walked through his doors: Celine Dion. In 1997, Rosenwaks helped the then-32-year-old have a baby with her 59-year-old husband/manager René Angélil.

In print

Rosenwaks wrote the book on in vitro, Reproductive Medicine Secrets, in 2004. He also serves on the editorial board of Fertility Today.

Drama

Rosenwaks' protégé, Jamie Grifo, left the clinic in 1995 with a number of staff members in tow after he complained that they were taking on too many patients. Grifo now runs a fertility clinic affiliated with NYU and is a top fertility specialist in his own right. Another defector, Dr. Jacques Cohen, is the scientific director of the Institute for Reproductive Medicine and Science at Saint Barnabas Medical Center in Livingston, NJ.

Personal

Rosenwaks and his wife Stacy Ann have two kids: a daughter, Gaelin, who does research on marine life at Duke, and a son named David. The couple lives on East 93rd Street.
