Founded in 1988 by Dr. David Diaz, West Coast Fertility Centers in southern California is now among the most established and successful fertility centers in the nation. There is nothing better than experience and during a career of 30 years, Dr. Diaz has developed a keen medical judgment and superior skills enhanced by a scientific intellect. At West Coast Fertility Center, the efforts of our fertility team have led to extraordinary pregnancy success rates by combining highly successful medication protocols, with scientific innovations in the disciplines of implantation and embryo culture. In addition, you have found one of the most successful unfertilized egg freezing programs anywhere, resulting in the birth of over 100 healthy babies and many more on-going frozen egg pregnancies.

In 1988, Dr. Diaz brought his knowledge and skills to southern California and founded West Coast Fertility Centers. He sensed a need to bring the most cutting-edge fertility treatments to Orange County, a beautiful community that lacked personalized fertility treatments in a harmonious environment. Dr. Diaz quickly assembled his team including embryologist, Dr. Dianne Smith, a Harvard trained scientist with 20 years experience in IVF. Cris Karl, Senior Embryologist, joined us from Cal State University- Fullerton. Teaching preceptorships were established to share surgical skills with local gynecologists and Dr. Diaz introduced advanced Operative Laparoscopy and Hysteroscopy to Anaheim Memorial Hospital, St. Joseph Hospital, St. Jude Medical Center, Coronal Regional Hospital and Irvine Medical Center.   His knack for innovation and unwavering dedication to excellence brought Dr. Diaz world recognition in the area of laparoscopic surgery and egg donation. In 1993, he gained notoriety for helping Mary Shearing, a remarkable 53 year old woman who broke the reproductive age barrier for women. Mary conceived and delivered twin girls. To this day, Mary continues to speak publicly about the joys of parenthood at any age for healthy women.
