Students Do I need an appointment to be treated? No, you don't. Walk-in patients are welcome, but we will set an appointment if you prefer. Will I see a doctor for treatment? You will be seen and treated by a Certified Family Nurse Practitioner (FNP-C), who has extensive training and background in family medical procedures. Can I pay cash or am I required to have medical insurance for treatment? Either. Nacogdoches Family Medicine accepts most medical insurance plans in the Nacogdoches area. I need a flu shot and maybe my pneumonia shot. Can you do that? Absolutely! Additionally, we can do TB skin testing and administer a broad range of immunizations and vaccinations.
