Meet our Doctors

Paul B. Payne, M.D.

Dr. Paul Payne was born and raised in Slaton, Texas. He attended Tulane University where he graduated with honors with a Bachelor of Science in Biology. Dr. Payne went on to obtain his medical degree from Texas Tech University School of Medicine. He did his residency at Baylor University Medical Center in Dallas and has been in private practice there since 1984. Dr. Payne is board certified in Obstetrics and Gynecology and is an attending physician at Baylor University Medical Center. While on staff at Baylor he has been named as outstanding teacher twice, and also has been named to Texas Monthly's Super Doctor list. His areas of interest include general obstetrics and gynecology, infertility, robotic surgery, high risk pregnancy, and menopause.

Dr. Payne's philosophy of medicine was formed by watching his father practice medicine as a small town general practioner in west Texas. He believes the most important thing for a physician to do is to stop and listen to his patients. This philosophy allows him to correctly apply the science of medicine on an individual basis. In so doing the doctor patient relationship grows in trust and respect. This belief is reflected in his attitude to treat the entire patient viewing himself as a primary care doctor for women, following them from puberty, through childbearing years, and into and through menopause.

Brian Welsh, M.D.

Originally from Midland, Texas, Dr. Welsh attended the University of Oklahoma where he studied Economics. Dr. Welsh knew he wanted to become a doctor junior year when he shadowed an orthopedic surgeon and witnessed first-hand how medicine has the power to restore peoples’ desired lifestyles. Upon graduating, Dr. Welsh pursued his medical degree at the University of Texas at San Antonio Health Science Center. He spent his first year of residency at ETSU and then completed his training at The University of Oklahoma. During residency, he was presented with the Outstanding Laparoscopic Resident Surgeon Award and multiple Resident Teaching Awards.

Dr. Welsh chose OBGYN because he loved the surgical field, but desired a long -term continuity with patients. He loves the fact that as an obstetrician he gets to play a small role in the most exciting of family events and has a special interest in high-risk pregnancy, adolescent gynecology, and hereditary carcinoma’s. He spent the last three years as a practicing OBGYN and partner at North Texas Women’s Health Care in Keller, Texas. During this time, he also served as a member of the Surgical Council at Texas Health Resources at Alliance.

Practicing what he preaches, Dr. Welsh enjoys an active lifestyle. His interests include fishing, volunteering, and chaperoning youth group mission trips, and hanging out with his two Flat Coated Retrievers, Cole and Odin.

Dr. Gunby said, "In addition to gynecology, I love the opportunity to provide well patient care to mother's who are pregnant.
