This crew is the great love of her heart! Jo graduated from Messiah College’s nursing program with a BSN. After working six years in various NICUs on the east coast she took a long break to be a full-time wife and mama.

She fully believes that those three years prepared her to step into the head nursing role at Hope Within. Her goal is to love and serve the people in the broader Lancaster, Dauphin and Lebanon County areas well as she puts hands and feet to her faith and she considers it an honor to do so. Besides enjoying all things “family” Jo enjoys reading, walking, talking and coffee with her girlfriends, and traveling.
