Dr. Alex Steinleitner
Dr. Steinleitner has been caring for infertile families for over 30 years. He is a fellowship trained Reproductive Endocrinologist and Infertility Specialist. He received his medical degree from the University of California, San Diego and completed his fellowship at the University of Southern California School of Medicine.
When in his research career, Dr. Steinleitner was recognized by his peers and awarded prizes for his excellent research papers submitted to the American Gynecological and Obstetrical Society, the Pacific Coast Reproductive Society, American Fertility Society, and the American College of Obstetrics and Gynecology.
He is particularly interested in the treatment of endometriosis and working to improve the results of infertility surgery. The American College of Obstetrics and Gynecology honored him with the CIBA fellowship award for his studies in menopause. He has also given international lectures on his techniques to better the outcome and quality of infertility treatment.
Dr. Steinleitner learned the true value of the work he does each day after raising his two college-aged daughters. Above any experience in life, being a father has taught him the most about the joy of adding a child to a family. Dr. Steinleitner believes that access to advanced infertility care is a matter of social justice, that’s why we make it our mission to make that care available to the widest range of families possible.
Dawn Kelk, PhD
Chief Scientific Officer
Dawn obtained a BSc in Molecular Biology and Genetics followed by MSc and PhD in Biomedical Sciences at the University of Guelph, Canada. She is board certified as a High Complexity Laboratory Director and is an active member of the American Society of Reproductive Medicine (ASRM), Society of Reproductive Biologists and Technologists (SRBT) and American Board of Bioanalysts (ABB).
Dr. Kelk’s primary clinical interest is in optimizing laboratory conditions, vitrification techniques and 24-chromosome testing for aneuploidy to increase confidence and utilization of elective single embryo transfer (eSET) leading to healthier IVF birth outcomes. Her research interests include oocyte and ovarian tissue freezing, fertility preservation, nuclear and cytoplasmic involvement in preimplantation development and fresh versus frozen IVF birth outcomes.
David L Hill, PhD, HCLD, ELD
Dr. Hill has a 35-year career creating and directing laboratories for in vitro fertilization / assisted reproductive technology (ART). He received his doctorate from the University of Connecticut and did postdoctoral training at Harvard Medical School. His career is notable for bringing several “firsts” to the Western United States, among them assisted hatching of embryos, sperm injection into human eggs (ICSI) to overcome male factor infertility and embryo biopsy.
Dr. Hill has a long list of publications and has presented his laboratory findings at national and international conferences. During his career he has seen success rates from frozen embryos grow from 1% to 50%. His areas of interest are providing cost-effective technology to couples struggling with fertility as well as using preimplantation genetic evaluative technologies to ensure “at risk” couples have babies free of heritable disease as well as identification of embryo gender prior to placement in the uterus to establish a pregnancy.
He resides in Hermosa Beach, California with his wife, Marianne G. Hill, MD.
