Dr. Sara Vaughn
Sara Vaughn, MD is a Board-Certified Reproductive Endocrinologist specializing in fertility and reproductive health. She was the former medical director at Spring Fertility in Silicon Valley. Dr. Vaughn completed her education and medical training at multiple universities: Rice, The University of Texas, Cedar Sinai Hospital, and Stanford Hospital. Dr. Vaughn frequently consults for Silicon Valley companies and VC funds that invest in fertility and women’s health startups. Dr Vaughn is drawn to Mate Fertility’s mission of improving quality fertility care for populations who have limited access to care.
Having undergone egg / embryo freezing herself, she provides a uniquely compassionate perspective. Her personal experience reinforced her passion for the work she does, and her desire to lead from a place of empathy and support. “My personal mission as a physician in management is to take care of the patients and the staff with similar ferocity. My goal with patients is not just to help them have babies. It’s to become successful parents. I tell my children, Donny and Eloise (age 6 and 2) that I do what I do so that people can have what I have. My job is to help guide patients though the medicine so they are left empowered, not depleted, by their fertility journey.”
She continues, “It’s truly shocking how many people have no access to care. Some are in locations where there are no fertility doctors. Some patients can’t afford it. Some patients belong to groups that require third party reproduction and the resources are just not there. We need to do better but we don’t have enough fertility doctors available to cover the need. Mate is creatively solving this problem and I feel honored and excited to be a part of it.”
