About Us

Dr. Gregory Shifrin, OB/GYN, PC is an Obstetrics and Gynecology focused medical office in Brooklyn, NY and the Upper East Side of Manhattan, NY. Our mission is to provide our patients with the best possible medical outcomes. To do this, we strive to employ only the most experienced and highly trained physicians and medical personnel; utilize the latest highly advanced equipment available on the market; and most importantly, prioritize personalized, attentive, and compassionate patient care.

At Dr. Gregory Shifrin, OB/GYN PC have developed a complete, all encompassing approach to patient care. Unlike other practices, which lack our years of experience and seek only to minimize costs, we seek to perform not only your initial exam, but also your ultrasound, your lab tests, and any procedures you may need. We do not overlook any detail, we make sure every aspect of your care with us is meticulously and carefully performed, and we give you--as a person--the care and attention needed to get you better.

We fret and obsess over every aspect of patient care, because our patients are individuals, with individual needs. We don't have a one size fits all solution, or a cure-all for every patient. Rather, we have developed a network of services which allows us to give each patient the exact care they need, individually, to get each patient their personalized best possible outcome.
