Introducing Our New RHS Principal and Associate Principal

Congratulations to Dr. Joseph MacNamara, Jr., our next Radnor High School Principal and Dr. Judy Lee, our new RHS Associate Principal who were approved at the Special Meeting of the School Board on Tuesday, July 11, 2023. The meeting was held virtually over Zoom.

Since 2020, Dr. MacNamara has served as an Assistant Principal at Radnor High School. Over the past three years, Dr. MacNamara has been a vital part of the success of Radnor High School, overseeing aspects of curriculum, discipline, school safety, working with teachers to develop their craft, and professional development. His dedication to creating a collaborative culture, cultivating strong relationships with students, staff, and parents, and promoting a well-rounded education for all, will undoubtedly shape the future of Radnor High School. Prior to Radnor, Dr. MacNamara worked at the Coatesville Area School District as an Assistant Principal. He began his career as a social studies teacher in 2006, after graduating from Millersville University. Dr. MacNamara earned his Doctor of Education from Immaculata University in 2020. We look forward to the positive impact Dr. MacNamara will have on our community as we continue to strive for excellence in education. 


As Associate Principal, Dr. Lee will report to the Principal, and she will provide support on all aspects of our High School programming with an emphasis on Teaching and Learning. Dr. Lee is an experienced educator and administrator who will be a tremendous asset to RHS. Currently, Dr. Lee is the Principal of Penn Wood High School in Lansdowne, where she has led several initiatives on curriculum development, scheduling, professional development, and post-secondary pathways. Prior to working at Penn Wood, Dr. Lee taught High School Mathematics in Philadelphia and was honored as a Lindback Educator of the Year Award for demonstrating excellence in promoting learning at the highest levels.  She began her career as a middle school math teacher in Seoul, Korea; and in 2009 she earned her Doctor of Education from Temple University.
