About Orange Coast Women's Medical Group

Dr. Han sees gynecology patients only and has narrowed her practice to women going through menopause. She says many of them come to her after feeling unheard or dismissed elsewhere. She describes care as a partnership where the patient has a voice in decisions. She works within Orange Coast Women's Medical Group, a large OB/GYN group with offices across south Orange County, and she sees patients in Irvine and Laguna Hills. The group's menopause page describes hormone therapy as pills, patches or vaginal creams, and lists non-hormonal options too. She earned a Master of Public Health at Harvard in 2023, focused on how social connection shapes health habits.
