I have been a practicing Reproductive Endocrinologist and Fertility Specialist for the last 25 years and am proud to be leading Oma Fertility’s New York City practice.

Originally from Massachusetts, I attended the University of Rochester where I obtained a bachelor’s degree in Biology, followed by graduation from medical school from the Case Western Reserve University School of Medicine. I then went on to complete a four-year OB/GYN residency at the Weill-Cornell Medical Center, in New York City, followed by a fellowship in Reproductive Endocrinology and Infertility at the Yale-New Haven Hospital. I have been double board certified in both OB/GYN and REI since 2000.

Following my fellowship, I returned to Massachusetts where I held faculty positions at both Tufts University School of Medicine/New England Medical Center and Brigham & Women’s Hospital/Harvard Medical School, participating in cutting-edge patient care at both institutions.

I returned to New York City in 2004 becoming the Medical Director of the Columbia University Center for Women’s Reproductive Care where I led a multi-physician, large infertility practice. While serving as the Medical Director at the Columbia Center for Women’s Reproductive Care, I attained a Master of Public Health Degree at the Columbia University Mailman School of Public Health.

Over the last 4 years, I have been practicing at Extend Fertility in New York City, with a primary focus on both infertility treatment and the emerging technology of oocyte cryopreservation.

Additionally, I have continued my academic, educational and community service mission as an Associate Clinical Professor of OB/GYN at the New York Medical College and a staff attending physician in the Department of OB/GYN at Metropolitan Hospital, which is part of the New York Health and Hospitals System.

During my 25 years of clinical practice, I have been committed to providing patients and their families the highest level of care and compassion while they undertake the sometimes rigorous and stressful journey of building a family. My highest priority remains the building of families in a safe, supportive and caring manner for all.

My association with Oma Fertility will allow me to continue my mandate to offer cutting-edge technologies to the practice of reproductive medicine and infertility.
