Sarah Jeffrey

Vice President - Education & Director - Mary Francis Bachmann School

Sarah joined CHI St Joseph Children’s Health as a Community Health Coordinator for Healthy Columbia in July 2021. She started her career as a High School Spanish Teacher in Hazleton – her experiences within this community motivated her to pursue a career in serving young people who lack access to basic needs. This led her to an opportunity to work for the Covenant House Pennsylvania as a Street Outreach Worker and Program Coordinator, providing shelter and basic needs to homeless teens in York. Through these experiences, she learned that every individual’s spiritual, emotional, and physical well-being impacts a community, and in turn, the community’s overall well-being impacts each individual. She was drawn to CHI St Joseph Children’s Health because of our demonstrated history of adapting to meet the changing needs of those we serve.

In her free time, she enjoys spending time with her cats, reupholstering furniture, and playing the guitar.
