Kind words from families

The nurse took her shoes off at the door without being asked. My mother decided right then she liked her.
Ellen V.Daughter of a patient, Georgetown
Andrew understood Dad's Parkinson's better than anyone we'd met. He got him walking the block again.
Chris D.Son of a patient, Round Rock
Luisa explained everything in Spanish to my grandmother, patiently, as many times as she needed.

They found two medicines that shouldn't have been taken together. Nobody else had noticed.

My knee replacement went better than my neighbor's, and I'm convinced it's because of the therapist.
