Executive Director
As Director of the Lancaster Medical Heritage Museum, Erin is honored to steward one of the region’s most unique cultural institutions—dedicated to preserving and sharing the rich history of healing in Lancaster County. With a background in American history, archival research, and strategic marketing, she brings a multidisciplinary approach to nonprofit leadership that blends storytelling, community engagement, and operational strategy.
In this role, Erin oversees museum operations, develops exhibits, coordinates public programming, and builds partnerships that amplify the museum’s mission. She’s passionate about making history accessible and relevant—whether through educational outreach, digital content, or collaborative research with students and medical professionals.
Her work is guided by the belief that history isn’t just what we preserve—it’s how we connect, inform, and inspire the community today.
