Mary Lou was a bright, outgoing, warm-hearted and compassionate woman, who cared very deeply about her family and those around her. She was very proud of her husband, her four sons, and her nursing career.

During her morning rounds, she would always talk with the patients under her care, even those who were non-responsive, believing strongly that all individuals should be treated with the utmost of dignity and respect. In later life, she enjoyed traveling and spending time with her husband and family, which provided them all with countless unforgettable fond memories.
