About
Dr. Ernest Zeringue is the founder and Medical Director of California IVF Fertility Center, serving as clinical lead since the center opened in 2004. He is a board-certified reproductive endocrinology and infertility (REI) specialist with a faculty appointment at the UC Davis School of Medicine.

This background gives him deep insight into military family needs, and the center offers dedicated Tricare and VA veteran discounts.

The center pioneered PGT in the region in 2005 and has achieved notable success in oocyte freezing and donor embryo programs.
