Personal Interests

Dr. Duff lives with her husband of 35 years, Bill, a retired electrical engineer. She loves discussing recent trends in medicine with her son, an anesthesiologist on the faculty at Baylor College of Medicine, and spending time with her grandson. She raises miniature dachshunds and enjoys gardening, antiquing with her sister, cooking, and reading.


Dr. Diana Duff cares for women in all walks of life and assists them in overcoming their health challenges. Dr. Duff and her team are there for women from adolescence through menopause. She partners with patients in developing evidence-based strategies for preventative care, contraception, childbearing, and change of life concerns. She expertly performs outpatient procedures including laparoscopy, and other minimally invasive procedures, as well as major gynecologic and urogynecological surgeries. Dr. Duff provides comprehensive obstetrical care, including high-risk OB, to promote a healthy outcome for both mother and child.

Dr. Duff is a native Texan with a proud family heritage. Her parents worked internationally, so Dr. Duff is a fluent speaker of Spanish. She understands and has shared the challenges and experiences of her patients in this dynamic Texas economy. Dr. Duff was recruited to serve a leadership role in the Pearland transformation to a full-service medical community. She is the first Chief of the Maternal/Pediatric Department at the new HCA Pearland Medical Center, as well as their Chief of Staff, and has been appointed to the Medical Executive Committee of “Pearland Careland.” She is a founding partner in the Southwest Women’s Health Alliance and Pearland Women’s Health.
