What People Say About Dr. Klaus-Dieter Lessnau, MD
Reply Flag
Thanks for teaching me the difference between Fact and Faith: Fact is when any ordinary doctor diagnoses illness in a report. Faith is when good doctors like you give their patients the strength to recover. There are no words to say how thankful we are for the care that was given to my mother Florence Esposito. Dr. Lessnau is a doctor that practices medicine for the care of his patient and went above and beyond to care for my mother. Thank You Jean Kern
