At Nod Specialist, headquartered in Phoenix, Arizona, we specialize in delivering quality healthcare for infectious diseases, kidney disease, and allergy and immunology issues. We’re dedicated to underserved communities and ailing patients in the comfort of their home, nursing home, rural hospital, or anywhere they might be.
