STAFF | HPMS

Sarah Terrell

Head of School

Sarah is in her 19th year at HPMS. Sarah discovered HPMS while working as a nanny for two girls who were attending the school.

When Sarah was three months pregnant with her daughter, Sarah put her on the waiting list to enroll at HPMS. In 2004, Sarah’s daughter began HPMS, and Sarah joined the school community as a volunteer. Before joining HPMS, Sarah was a nanny for ten years. In 2006, after volunteering for several years, she joined the HPMS staff as an Assistant. She soon became the Afternoon Care Guide. In 2014, Sarah took on her current role of Toddler Community Guide.
