Primary Care Associates
Finding a family care physician can be a challenging process, but at Guadalupe Regional Medical Group (GRMG) we try to make things as easy as possible. All our family practice physicians can take care of your entire family, whether infants, children, teens, adults or seniors. By being able to care for your whole family, it’s not only convenient for you, but it also provides the physician an ongoing family medical history. In a community like Seguin, we love to take care of our patients and their families – now, and well into the future.
