Our History

UMC Physician Network Services (PNS) is a physician practice management group formed by UMC in 1996 to manage the hospital’s Community Health Centers and to develop a broad base of primary care patients that would support the hospital and medical school.

Since its inception, it has grown to over 100 providers representing all primary care specialties – family practice, family practice with obstetrics, internal medicine, and pediatrics, complemented with mid-level providers including both physician assistants and nurse practitioners. PNS has associations with physicians specializing in podiatry, gastroenterology, pediatric surgery, bariatrics, allergy and immunology, obstetrics and gynecology, and pediatric development.

Our support staff consists of more than corporate headquaters 450 experienced health care employees composed of nurses, ancillary services, and administrative professionals. We have approximately 45 practice sites located throughout Lubbock and the surrounding area including community health centers, private physician practices, and urgent care clinics open seven days a week. PNS operates health clinics at two Lubbock United Supermarkets. Combined, these practices provide care to 385,000 patients annually.
