Dr. Alexa Williams is a board-certified obstetrician and gynecologist who provides compassionate, comprehensive care for women at every stage of life. She offers full-spectrum OB/Gyn services, including both low- and high-risk obstetrics, routine gynecologic care, and preventive health services. Her practice also includes natural family planning, with specialized training in the Creighton Model and NaProTechnology, offering women evidence-based options to understand and work with their fertility.

Passionate about patient education and partnership, Dr. Williams values listening to each woman's unique needs and tailoring care that respects each person's goals and overall health. Her aim is to create a safe, welcoming space where patients feel supported, respected, and cared for-whether it's during routine visits or some of life's most important moments.

Outside of medicine, Dr. Williams is a devoted wife and mother of six. She enjoys cooking and baking healthy meals, decorating and renovating her home, reading, and deepening her Catholic faith-which guides both her personal life and her approach to patient care.

She is a proud member of the Catholic Medical Association, and the American Board of Obstetrics and Gynecology.
