Dr. Sunny Jun is the Co-Founder and Co-Medical Director of CCRM San Francisco and is board certified in Obstetrics and Gynecology and Reproductive Endocrinology and Infertility. After her subspecialty training, she spent almost 10 years as a founding member of the Department of Reproductive Endocrinology and Fertility for the Palo Alto Medical Foundation in the East Bay.

“One of the things I love most about working at CCRM San Francisco is being able to provide high-quality, personalized care to each of my patients. We’re fortunate to have access to some of the most advanced IVF technology available, which gives our lab an incredible ability to help patients build their families. What’s most meaningful to me, though, is forming trusting relationships with the people I care for. Infertility can be an emotional and challenging journey, and I feel honored to walk alongside my patients—offering support, guidance, and hope every step of the way. We also have an amazing team here, all focused on making sure our patients feel heard, supported, and cared for. That patient-first approach is at the heart of everything I do.”
