Professional Statement

  • I am a nurse practitioner in Obstetrics and Gynecology specializing in maternal-fetal medicine.  I began working at Stony Brook in 2000 as an RN with experience in maternal/child health.  In 2008, I later joined the Department of Obstetrics and Gynecology working as an NP.  My role in the department of maternal fetal medicine is primarily direct patient care in women’s health, in particular high risk pregnancies.  I graduated from Pace University with a bachelor’s degree in nursing in 2000 and from Stony Brook University with a Master’s of Family Health in 2004.
