Marlane Angle, PhD, HCLD

Dr. Angle has been an embryologist and In Vitro Fertility laboratory director for over 25 years. Moving into the embryology laboratory was the practical synthesis of her graduate studies in embryo and sperm biochemistry/physiology and her NIH postdoctoral work on implantation and fetal developmental biochemistry.


She has directed embryology, andrology and endocrine laboratories in Las Vegas, NV, Seattle, WA and Little Rock, AR. She was among the first group of embryologists to become certified as High Complexity Laboratory Directors by the College of American Pathologists in 1995 and has published frequently in the fertility literature.


She is one of the founders and organizers for the Southwest Embryology Summit, has served on multiple boards and committees of various professional societies, is on the guest faculty for the Master’s Program in Embryology at the Eastern Virginia Medical School and has consulted and lectured around the world, particularly in the areas of pH and temperature management in the laboratory, and embryo and oocyte vitrification. She currently lives on her sailboat in Alameda, CA and directs a laboratory in San Francisco, CA.

John Buster, MD- Founder, Board Director, & Scientific Advisory Board Member

Dr. Buster has nearly four decades experience as a physician, almost entirely focused in the field of Reproductive Endocrinology and Infertility. He is highly experienced in the performance of assisted reproductive technology procedures, medical treatment for infertility and recurrent pregnancy loss, and various reproductive surgical procedures. Due to his extensive background; he is a frequently invited lecturer, consultant and participant in national and international forums.


Serving as a foundation for Previvo, Dr. Buster directed the research team at UCLA Medical Center that performed history's first embryo transfer from one woman to another resulting in a live birth. In the procedure, an embryo that was just beginning to develop was transferred from one woman in whom it had been conceived by artificial insemination to another woman who gave birth to the infant 38 weeks later. The sperm used in the artificial insemination came from the husband of the woman who bore the baby.


This work established the technical foundation and legal-ethical framework surrounding the clinical use of human oocyte and embryo donation, a mainstream clinical practice, which has evolved over the past 30 years. Building upon Dr. Buster's research and since the initial birth announcement in 1984, well over 200,000 live births resulting from donor embryo transfer have been and continue to be recorded by the Centers for Disease Control (CDC) in the United States to infertile women, who otherwise would not have had children by any other existing method.

Santiago Munne, PhD- Board Director & Scientific Advisory Board Member

Dr. Munné gained his Ph.D. in genetics from the University of Pittsburgh and joined Dr. Jacques Cohen at Cornell University Medical College New York in 1991. There he developed the first Preimplantation Genetic Diagnosis (PGD) test to detect embryonic numerical chromosome abnormalities such as Down’s Syndrome and other abnormalities. 


From 1995 to 2001, Dr. Munné was director of PGD at the Institute for Reproductive Medicine and Science of Saint Barnabas, where he also developed the first test to detect chromosome translocations in human embryos.


In 2001, Dr. Munné co-founded Reprogenetics, with Jacques Cohen and David Sable. He directed the company until 2016 and saw its expansion to four continents. Reprogenetics was the first commercial lab to offer PGS and PGD and was the market leader until it was sold in 2015 to the Cooper Companies (NYSE: COO). During this time Reprogenetics performed over 70,000 PGD cycles globally. Reprogenetics stayed in the forefront of research and development focusing on the use of comprehensive genetic analysis of embryos in order to improve pregnancy outcomes and diminish the risk of miscarriages in gene and chromosome inherited disorders. Dr. Munné and co-researchers were rewarded with SART prize papers in 2005, 2015 and 2016, and he has received The American Society for Reproductive Medicine Star Award consecutively for the years 2011-2016.
