Pamela Watson is a Family Practice Nurse Practitioner at the Ralph H. Johnson VA Health Care System

Board Certified: Yes - Adult and Geriatric Primary Care
I provide home based primary care for veterans with disease processes that prevent them from easily getting out of their home for medical appointments. The care that is provided in their home allows me a unique perspective of what their health care limitations are. I have an opportunity to overcome these obstacles to promote better health by building relationships & supporting not only the patient, but the entire family.
I have a 2 year old grandchild that I adore and spend as much time as possible with. We also have a farm in TN that we visit frequently.
