Women's Health Care Center of Houston


The physicians at WHCCH have a long, storied history of providing patient care for women and delivering babies. In fact, WHCCH’s founder Dr. Byron Holt, who began his practice in 1966, has delivered more than 40,000 babies throughout his career.

All hailing from Texas and completing their residencies in the Lone Star State, WHCCH’s six physicians, all board-certified in obstetrics and gynecology, bring their unique experiences and knowledge into an women’s health care practice that has delivered exemplary and compassionate medical care to multiple generations of women in the greater Houston area.

What Does FACOG mean?

You’ll notice that each of our physicians has the FACOG designation after his or her name and degree. According to the American Congress of Obstetricians and Gynecologists’ website:

 “Trust begins with knowing that a doctor is qualified. All ob-gyns have earned their undergraduate college degree and have completed an additional four years of medical school. After receiving their medical degree, ob-gyns complete four years of residency training in obstetrics and gynecology; after this they may elect to become board-certified. Certification recognizes that a doctor has graduated from a recognized medical school, completed an accredited residency program, has an unrestricted license to practice medicine, and has passed extensive exams given by the American Board of Obstetrics and Gynecology.

The initials FACOG after a physician’s name indicate that he or she has met additional criteria to qualify as a Fellow of The American Congress of Obstetricians and Gynecologists. By choosing an ACOG Fellow as your physician, you can feel confident that you will receive the highest quality health care. Choosing an ACOG Fellow as your physician ensures that your ob-gyn is being kept abreast of the latest medical guidelines, treatments, and techniques in women’s health care today.”
