Celebrate Nephrology Nurses Week September 13-19 as a way to thank, honor and recognize these highly dedicated members of the medical community. ANNA, the American Nephrology Nurses Association, marks this occasion during the second week of September. Everyday, nephrology nurses use their education, skillsets and kind demeanor in order to provide kidney patients with life-saving — and life-changing — work. This year, the theme is “Nephrology Nurses Aspire to Excellence.”
