David Sutherland

Assistant Principal - Grade 8


603-432-6925 ext. 3277

Mr. David Sutherland will begin his 11th year as an Assistant Principal of the Londonderry Middle School.  Mr. Sutherland's career in education started after he determined that being a software and hardware quality assurance manager was not fulfilling.  He had earned an undergraduate degree in Business and Management Information Systems from Northeastern University and thought that the computer industry was where he wanted to spend his time.  However, he left that field to pursue being an educator.  


He started his educational career at a charter school in Malden, Massachusetts, and while working as a teaching assistant, he pursued a  Graduate Degree in Elementary Education from Lesley University in Cambridge, Massachusetts. Upon completing his degree, he entered the classroom as a 6th-grade general education teacher and Lead teacher, and after three years in that position, he left the public charter school environment and worked as a 6th-grade Science Teacher at the Rupert A. Nock Middle School in Newburyport.


He married his wife, Leah, and in 2007 they decided to purchase a home in Londonderry, closer to his new teaching job in Bedford, N.H., at  McKelvie Intermediate School as a sixth-grade Math, Science, and Social Studies teacher.  While teaching sixth grade, he enrolled at Rivier University and earned an advanced degree and Principal Certification.  After five years, David decided to move into a leadership position. In 2012, he took a position as an  Assistant Principal in the Allenstown School District, and after serving a year, an opportunity became available in Londonderry at the Middle School, where he jumped at the chance to work for the school district and his hometown. Since joining the Londonderry Middle School in 2013, he earned his Certificate of Advanced Graduate Study in Competency-Based Education through SNHU in 2021


Dave is proud to be a part of the Londonderry community and serve the families as the assistant principal of Londonderry Middle School and enjoys working, living, and raising his two daughters in a close-knit community. Dave is an active community member and can be seen on the sports fields, where he enjoys watching his two daughters, Jordan and Reese, play softball, soccer, and volleyball. When they aren't on the sports fields, he enjoys fishing with his kids and other recreational activities with his family, such as camping, hiking, and mountain biking.   


Working with such a talented and dedicated group of educators is a privilege, and he enjoys going to work every day to help the staff and students be the best they can be.
