I would like to extend a warm welcome to Northfield Elementary School. I am excited and honored to serve the Northfield students, staff, and families! As an educator, I believe that all students should have the opportunity to participate in rigorous and highly engaging instruction each day. At Northfield, we strive to provide opportunities for students to be enthusiastic about learning as they participate in meaningful tasks, and work collaboratively to solve problems. The Northfield community has a strong reputation for working together to provide a rich, and well-rounded education for our students. We have many parent volunteers, a large and active PTA that sponsors numerous family and learning events, and numerous after school programs. With the support of the entire community, we maintain Healthy Howard Gold Status, and we are a Maryland Green School. Recently, Northfield became one of only thirty-one schools nationally to earn the Eco-Schools USA Green Flag Award. We always welcome parents as partners in education, and I maintain an open door policy. Parents are encouraged to visit, call, email (tiffany_tresler@hcpss.org) with any questions, comments, or feedback. I joined the Northfield family, and Howard County Public Schools, as principal in February 2014. My background includes serving as an elementary assistant principal for three and one half years, providing teacher professional development and Title I grant management for two years, and working as an elementary classroom teacher for five years. I received a bachelor's degree in elementary education from Shippensburg University in Pennsylvania, and a master's degree in school administration and supervision from Frostburg State University in Maryland. I recently earned a doctorate from the University of Maryland in educational leadership and policy studies. Working with students and teachers for continuous growth and learning is my passion, and I can often be found in classrooms, or meeting with teachers to discuss instruction. Once again, welcome to the Northfield community! Please do not hesitate to contact me if you have questions about our world-class school. Tiffany Tresler, Ed.D. Principal tiffany_tresler@hcpss.org

We are the 5th school in Maryland and 31st school nationally to earn this status.

Eco-Schools is an internationally acclaimed program that provides a framework to help educators integrate sustainable principles throughout their schools and curriculum.

The Eco-Schools program was started in 1994 by the Foundation for Environmental Education (FEE) with support by the European Commission. It was identified by the United Nations Environment Program (UNEP) as a model initiative for Education for Sustainable Development in 2003.

The Eco-Schools program strives to model environmentally sound practices, provide support for greening the curriculum and enhance science and academic achievement.

Additionally, it works to foster a greater sense of environmental stewardship among youth.

Eco-Schools is currently being implemented in more than 50 countries around the world.
