Principal
Mrs. Evanthia Filiou was born in Upper Darby, PA, and spent most of her childhood in Springfield, PA. After graduating from high school, she attended St. Joseph's University and earned a BA in English, with a minor in secondary education. Her goal at the time was to become a college professor, and so she pursued her master's degree in English, with a concentration in creative writing, at West Chester University.
Mrs. Filiou's first teaching position was in a middle school. After a year, she transferred to the high school level until she became a secondary literacy specialist. She continued her studies by earning both a reading specialist's certificate, as well as her school leadership credential. She served as an assistant principal in the Lake Forest School District for seven years before joining Mount Pleasant High School.

Dr. Nicole Hyland
Assistant Principal
A Bit About Dr. Hyland…
I have been an educator for 20 years, serving students from birth to age twenty-one across public, charter, specialized, agency, and in-home settings. Within the Brandywine School District, I have held roles as Coach, Special Education Teacher, Special Education Coordinator, Dean of Students, and Assistant Principal.
My foremost reason for entering education—and the motivation that still drives me today—is a genuine desire to serve young people and help them thrive. I am deeply grateful for the many opportunities I’ve had to make a meaningful difference in my students’ lives. I believe that when an educator helps a young person recognize the promise of their own future, it is a job well done.
In addition to being the proud mother of three extraordinary young adults, I have contributed to the field through doctoral research examining alternatives to student exclusion—specifically Positive Behavior Interventions & Supports, Restorative Practices, and Social Emotional Learning.
The sum of my personal and professional experiences has shaped a strong core belief in the boundless possibility of every young person. While success may look different for each student, I firmly believe that all students have potential and are deserving of the very best we have to offer.
I am thrilled to be part of the Mount Pleasant High School community and look forward to a fantastic year ahead.
Let’s go Green Knights!
