Teaching and Training

Orange County Fertility Surgeon Doctor David Diaz at West Coast Fertility Centers

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' love for teaching continues in private practice today providing tutorials for visiting physicians, nurses, industry representatives and, most importantly, educating his patients at West Coast Fertility Centers.
