Tim Hannigan was first inspired to teach after working at Treasure Island Scout Reservation as a teenager, instructing scouts in nature and camping skills. This experience led him to discover and appreciate the importance of making lessons personal and relevant to a student.

Tim earned his Bachelor of Arts in Secondary Education with a concentration in Social Studies from La Salle University and his Master of Arts in History from Montclair State University. In 1997, he began working in schools in Philadelphia through City Year, an AmeriCorps program, teaching life skills, organizing service learning projects, and running after school programs in Title I schools. After that valuable experience, Tim taught professionally at University City High School in Philadelphia.

The following year, Tim left Philadelphia for northern New Jersey to teach at Morristown Beard School, seeking an opportunity to work at a school where collaboration and academic freedom in instruction is welcomed and encouraged. He joined the MBS History Department Faculty in 2000, starting in the Middle School before eventually moving to the Upper School in 2004.

Over the last eighteen years, Tim has served MBS in a number of capacities that have enabled him to contribute to the school community while developing his professional skills as both an educator and administrator. He is currently the advisor for the Model United Nations Club, and has previously served as the Grade Dean for the Class of 2009, the Chair of the History Department from 2011-2017, and as an assistant coach for the swim and cross country teams.
