We Are

Located in the Haley Building on the corner of Pembroke Street and Academy Road.

Our nine schools provide pre-K through 12 educational experiences for approximately 3,100 students. Pembroke Academy serves as the high school experience for students from the communities of Allenstown, Chichester, Epsom and Pembroke. The majority of Deerfield students attend Concord High School.

All our schools embrace the vision of 21st Century Learning with the integration of technology at the forefront of what we do with our students each day.

Our hours of operation are:
Regular Hours: Monday-Friday 8:00am – 4:00pm
Summer Hours: Monday-Friday 8:00am – 3:30pm


Our Central Office is structured using an innovative superintendent model.  Each superintendent has sole responsibllity for specific districts.

  • Patricia Sherman leads the Deerfield and Pembroke School Districts as well as both the SAU Full Board and the SAU Executive Board and oversees the day to day operation of the SAU Central Office.
  • Peter Warburton, leads the Allenstown, Chichester and Epsom School Districts.

SAU employees include central office staff and a number of teachers and “specialists” who work in school buildings, but are billed through the SAU. This occurs in SAU sponsored programs like Pre-School\TLC or in alternative programs like Bridge. It can also occur as a cost saving measure when a school needs a specialist such as psychologists or Occupational/Physical/Speech Therapist, but do not need them full time.

The SAU Central Office itself in managed and directed using a “Shared Leadership Model” by a team of administrators, often referred to as COLT – The Central Office Leadership Team. The following administrators are members of COLT.
