Sue Sadler is The Bryn Mawr School's tenth head of school. She comes to Bryn Mawr from Hathaway Brown (HB), an all-girls school in Shaker Heights, Ohio, where she served for 31 years in a variety of capacities including most recently as the associate head of school and Upper School director. She has managed several facilities updates, including a state-of-the-art innovation lab and a learning commons within the school library. She was also instrumental in launching HB’s Center for Leadership and Well-Being and brought together the wellness and leadership resources in the school to create “Be Well, Lead Well,” an early childhood through grade 12 program that helps students build strong and healthy internal and external resources to become leaders in their own lives.
 
Throughout her career, Sue has been recognized for excellence in teaching, such as through the establishment of the Sadler Promise in Education Award, initiated by an HB alumna donor. Sue holds a Bachelor of Arts in Biology from Colby College, and a master's in the Arts of Education from Ursuline College.
