Mrs. Sandra DuPlain

Students, Parents and Colleagues,

Welcome to a brand new year at Canyon del Oro High School! This year, I am excited to be teaching on-level 9th and 10th Grade English. I am a proud University of Arizona Alumni with degrees in Political Science and History. Additionally, I have a Master's degree in Sociology from Arizona State University. Certifications and areas of expertise are in English Language Arts, Reading Specialist and English Second Language. Over the years, I have been honored to work with high performing student-athletes achieving Coach of the Year for tennis and leading teams to state championships in Texas and Arizona.

My teaching philosophy is simple: Students are dignified, capable and mature scholars, encouraged to achieve greatness in their learning environment. In my spare time, I enjoy traveling with my husband, spoiling my Grandson, hiking in the Catalina Mountains and volunteering with the Rotary Club and Junior League.

I hope you find the contents of this site helpful. The website will be updated weekly with the addition of assignments and resources for students and parents. For further information, please feel free to contact me at:, or directly at (520) 696-5648.

It is a great day to be a Dorado!
