Dr. Tran graduated at the top of his medical school class before arriving at UCSF, where he completed both his residency in Obstetrics & Gynecology and fellowship in Reproductive Endocrinology. After fellowship, Dr. Tran joined UCSF as Assistant Professor of Obstetrics & Gynecology and the Principal Investigator at the Center for Regenerative Medicine, where he became a leading clinical researcher in ovarian insufficiency, endometriosis, and stem cell research. Dr. Tran is board certified in both Obstetrics & Gynecology and Reproductive Endocrinology & Infertility.
An award-winning physician-scientist with many grants, publications, and ground-breaking discoveries, Dr. Tran’s research mirrors his clinical interest in premature ovarian failure, endometriosis, and azoospermia. He was the first to generate primordial germ cells from patients with premature germ cell failure to investigate possible cures. He also patented a “first of its kind” procedure that uses sperm stem cells to treat male infertility, which earned the Society of Male Reproduction & Urology Scholar Award and the American Society of Reproductive Medicine (ASRM) Scientific Prize Paper winner 2015.

Dr. Vaccari has been at the forefront of clinical and scientific advances in reproduction for the last 15 years and has been widely recognized for his research on oocyte maturation and embryo culture technology. He’s most well-known for developing a non-invasive assessment of frozen embryo viability. During his fellowships at Stanford University and UCSF, he discovered that key signaling pathways were necessary to facilitate egg maturation and development. Dr. Vaccari’s research and discoveries in egg and embryo development have led to numerous publications in peer-reviewed, scientific journals. Dr. Vaccari holds a PhD in Cellular Technology from The Department of Human Embryology and Histology in Rome, and a BS in Biology from The Italian Institute of Health. He also holds a professional certification as a High-complexity Clinical Lab Director.
Dr. Vaccari credits his lovely wife, Dr. Torcia, for introducing him to the study of eggs and embryos, and the miracle of IVF for helping them achieve their dream of a beautiful family. He looks forward to helping others fulfill their dreams of creating a happy, healthy family through IVF.
Dr. Torcia is a highly-regarded embryologist known for her relentless pursuit of excellence and record of innovation. Before embarking on clinical embryology, Dr. Torcia was an accomplished research scientist at both Stanford and UCSF, where she published her work in the prestigious journal Nature Cell Biology. Her previous research focused on gene expression during preimplantation embryo development, and now focuses on optimizing oocyte vitrification and in vitro oocyte maturation. Ten years ago, she transitioned toward human-assisted reproduction at UCSF and has continued to develop new techniques and push for excellence at multiple embryology labs. At Spring Fertility, she is committed to giving each embryo the best chance of survival possible and continues to focus on developing new embryo culture techniques, as well as egg and embryo cryopreservation.
Dr. Torcia is extremely dedicated, meticulous, and joined Spring to deliver the highest quality fertility care to ensure that everyone has the ability to have a family. When not in the lab, she enjoys spending time with her husband, Dr. Vaccari, and their three year old daughter.
