Dianne graduated from Saint Marys Memorial High School in 1967, and then started nursing school at St. Ritas Hospital Nursing School in Lima, where she graduated in 1970 as a Registered Nurse. She was one of the first two nurses to work in the emergency room of Joint Township District Memorial Hospital, a role she filled for 27 years. She later worked at the family practice of Dr. John Bowling and also Saint Marys Family Practice.

Dianne was a very kind, social person with a large group of friends whom she loved getting together with on a regular basis. She and her high school friends formed a card club over 50 years ago, and they also took a yearly vacation together. 
She also enjoyed going to eat with her many retired friends from JTDMH and Dr. Bowling's family practice, including a weekly Wednesday breakfast at the Friendly Tavern, and an annual dinner with her friends from nursing school. She liked attending the sporting events of her nieces and nephews, all of whom Dianne considered her own children, and treated them with much love and care.

She was a lifelong member of Holy Rosary Catholic Church, where she was a lay communion distributor and also helped organize and run the church garage sale for many years. She recently learned how to play Mahjong and joined a club at the local library. Dianne will be remembered as a very thoughtful, fun person who wanted the best for everyone.
