Principal's Message

Message to our students and families,

I would like to make a brief introduction to our wonderful community. I am very eager to come to a school with such a rich history dating back to the mid-1800s, which has been integral to our Markham community as a center of learning and student development. With optimism I look forward to when we can connect personally as we as a community, country and globally move to a more normative stance in this school year.   

I would like to share with you my journey as an educator and how many of those experiences has shaped and influenced my core beliefs that all students can grow and succeed.  I was a teacher for 9 years in the Toronto District School Board, beginning my career at Cedarbrae Collegiate and then moving onto Emery Collegiate, Nelson A. Boylen and was centrally assigned as an Instructional Coach for two years as part of a Ministry of Education initiative. I joined the York Region District School Board in 2014 and settled in the Markham community when I was appointed Vice-Principal at Milliken Mills High School, followed by Pierre Elliott Trudeau High School. During this school year, I will get to know our building, our community, and familiarize myself with the unique needs of our school. I believe that with great challenges come great opportunities.

I am truly honoured to be given this opportunity and look forward to immersing myself completely in our school, in our community and becoming a MDHS Marauder! I believe that one of my main responsibilities is to provide our students with a caring, safe and engaging educational program while supporting our teachers as they continue to provide exemplary programming to our children.   

As we begin our educational journey together, I trust that we will form a strong collaboration, which will support your children to become lifelong learners, ready to support themselves and their community to the future. In partnership with the staff at Markham District High School, we will collectively provide instruction and programming that is challenging, engaging and varied to meet the needs of our children’s education and ensure they feel they belong to the school.



Ms. Coretta Sampson

The Proud new Principal of Markham District High School
