With nineteen years in the field, Joseph Brereton has served as a principal for thirteen years in the Central Bucks District, at the helm of Simon Butler Elementary School for eight years, where he oversees almost 850 students. In just a decade, Brereton rose to the challenge of three new building assignments while consistently mentoring new principals and serving as an important resource to the entire district. At Butler, he initiated a popular and successful collaborative PLC model that maximizes teacher contributions while utilizing staff strengths to help everyone grow, learn, and flourish. A culture of continuous learning places the success of every student at the center of all efforts with a focus on individualized instruction. This approach led to the development of a K-6 guided reading model, which was then implemented at the district level. Brereton emphasizes growth in professional practice and Butler teachers are routinely chosen to provide professional development to staff at the fourteen other district elementary schools. He served as Chair of the Central Bucks School District’s Strategic Planning Committee for Best Practices in Curriculum, Instruction, and Assessment, member of the Pennsylvania Association of Elementary and Secondary School Principals, and has been a member of the University of Pennsylvania’s Educational Leadership Advisory Board. He holds a M.S. and Principal Certification from the University of Pennsylvania and is working toward a Ph.D. in Comparative and International Education at Lehigh University.
