About Us

GREFI is an acronym in English for Gynecology Endocronology Reproductive Fertility Institute, and was founded in 1991 by Dr. Rosa Ileana Cruz Burgos in San Juan.  Dr. Cruz is a graduate of the University of Puerto Rico Medical Sciences Campus in 1980. In 1984 she completed her specialty in Obstetrics and Gynecology at the University Hospital of Medicine and proceeded to do her fellowship in Reproductive Endocrinology and Infertility at the Rutgers Medical School in New Brunswick, New Jersey. Today, she is the Director of the Department of Reproductive Endocrinology and Associate Professor of the Department of Obstetrics and Gynecology, Medical Sciences Campus and the School of Medicine in Ponce, PR.  Dr. Cruz is the only physician in Puerto Rico to be dual certified and re-certified by American “Boards” in both disciplines.

Dr. Cruz’s commitment to her profession and patients is described as outstanding.
