He serves as Associate Clinical Professor in the Department of Obstetrics and Gynecology at the David Geffen School of Medicine at UCLA. He is also Associate Director for Advanced Technologies at the Center for Fertility and Reproductive Medicine at Cedars-Sinai Medical Center.

Dr. Surrey is a prolific researcher, authoring numerous publications for leading peer-reviewed journals including Fertility and Sterility and the Journal of Assisted Reproduction and Genetics.

As a fertility expert, Dr. Surrey is committed to supporting each patient’s ability to have a successful pregnancy and the healthiest baby possible. Voted one of the “Top 100 Health Professionals” and listed in “Best Doctors in America,” Dr. Surrey’s ability to help people achieve their fertility goals has made him a physician of choice for patients from all over the world for more than 25 years. This has led him to pursue rigorous training in pelvic reconstructive surgery, microsurgery and laparoscopic surgery, IVF and preimplantation genetic diagnosis (PGD).

Used in IVF procedures, PGD allows embryos to be screened for single gene disorders such as cystic fibrosis, sickle cell anemia and Tay-Sachs disease. Many more human diseases are caused by defects in a single gene. PGD can help avoid miscarriage and improve the chances of a successful pregnancy. Dr. Surrey is also pursuing research that can improve embryo implantation, reduce the risk of multiple pregnancies and advance the success of embryo transfer.

Dr. Surrey earned his bachelor's degree from the University of Pittsburgh and his M.D. from George Washington University. Following an internship and residency at UCLA Medical Center, he completed a research Fellowship in Reproductive Endocrinology and an Infertility Fellowship at the University of London, Hammersmith Hospital. He trained in preimplantation genetic diagnosis at the University of London and Monash University, Melbourne.
