Welcome to the Head of School Search page for St. Andrew’s College, where our community can follow updates and learn more about the search for the next Head who will build forward – honouring our proud traditions while leading SAC into its next chapter.

 
A Message from the Chair of the Board of Governors
 
Dear SAC Community,
 
On behalf of the Board of Governors, I am pleased to share that Colby Dockerty has been appointed the ninth Head of School of St. Andrew’s College, effective July 1, 2027.
 
Following a comprehensive search process supported by an executive search firm, Colby emerged as the strongest candidate, best positioned to guide SAC into its next chapter. Throughout the process, the Search Committee was encouraged by Colby’s educational leadership, strategic thinking, relational approach, and deep understanding of the mission, traditions, and culture that define St. Andrew’s College.
 
Since joining SAC in 2015, Colby has served the school in many capacities, including teacher, coach, boarding supervisor, academic leader, and Director of Middle School. He has played an important role in several strategic and academic initiatives across the College and has been involved in the SAC-SAS Partnerhood.
 
This appointment reflects continuity and forward momentum for SAC. Colby believes in the values and traditions that define the school while also embracing innovation, future-ready learning, global engagement, and continued excellence across academics, arts, athletics, and boarding life.
 
One of the many strengths of this appointment is the thoughtful transition period ahead. During the 2026-2027 academic year, Colby will work closely alongside Kevin McHenry, Sabrina D’Angelo, Head of St. Anne’s School, and the Leadership Teams to support continuity, collaboration, and long-term success across both institutions.
 
Leadership transitions are among the most important moments in the life of a school, and we are excited to welcome a leader our community already knows, trusts, and believes in.
 
On behalf of the Board of Governors, thank you for your continued support, engagement, and confidence in the future of SAC. The full announcement can be found below.
 
Sincerely,
 
Mark Etherington ’92
