Wonderful app for first responders and healthcare workers, nurses, and doctors.

My Mom was an RN from ‘67, an EdD, and she was Dean of Nusing at Lewis University until she retired in her late ‘60s. My Daughter is an MA with three courses to go for her RN. I started working for Civil Defense in ‘67, today I work for TINLEY Park EMA, and do consulting for several Federal Agencies and DOD.

We all find the app and it’s content incredibly invaluable.
