Dr. Diaz' Biosketch

During his Gynecological training program at the University of Missouri, Dr. Diaz developed an interest the treatment of infertility during his training in  endometriosis surgery, uterine reconstruction for fibroids, tubal repair and all aspects of vaginal surgery. He established the first microsurgical laboratory for training resident physicians and medical students in the technique of microsurgical unification for tubal repair. His mentor, Dr. William Griffin, encouraged him to pursue advanced fellowship training. 

Dr. Diaz was awarded a two year Fellowship in Reproductive Endocrinology at Harvard Medical School, Beth Israel Hospital in Boston, Massachusetts. His training was supervised by Dr. Melvin Taymor, whose team of scientists achieved the first IVF pregnancy in New England (1984). Dr. Taymor was responsible for introducing the use of the fertility drug Pergonal to the United States in collaboration with Dr. Bruno Lunenfeld from Israel. Dr. Diaz performed research in the development of medication protocols for IVF that led to one of the highest pregnancy rates in the nation. At Harvard, Dr. Diaz was taught the art and science of in-vitro fertilization at Boston IVF, the largest private IVF clinic in the world, working with renowned experts :  Dr. Michael Alper, Dr. Irwin Thompson, Dr. Merle Berger and Dr. Selwyn Oskowitz. The training program at Harvard was complemented by specialty training in the area of reproductive surgery.

One of the most memorable aspects of Dr. Diaz’ training was the intensive exposure to advanced laparoscopic and hysteroscopic surgery under the tutelage of Dr. Robert Hunt , a world authority in fertility enhancement surgery, whose  inspiration led to the publication of several chapters in the classic textbook: Atlas of Female Fertility Surgery.  Dr. Diaz’ enthusiasm in surgery led to a European experience when he was invited to Kiel, West Germany by Professor Kurt Semm, the inventor of many laparoscopic instruments still routinely used today.

Teaching was an integral part of the Fellowship Program. Dr. Diaz was appointed to the teaching staff at Harvard Medical School as Instructor in Obstetrics and Gynecology with an emphasis in Reproductive Endocrinology and Infertility. Teaching was a passion of Dr. Diaz since he minored in education at Loyola University in Chicago. The Harvard teaching duties included Grand Rounds presentation, informal teaching of medical students and OB/GYN residents plus mentoring visiting students from around the world. Dr. Diaz’ enthusiasm for teaching continues in private practice providing tutorials for visiting physicians, nurses, representatives from industry and most importantly educating his patients at West Coast Fertility Centers.   

We invite you to share in the West Coast Fertility Center Family and receive the high quality care you have been seeking. This is our promise to you.
