Students, Parents and Colleagues,

Welcome to a brand new year at Canyon del Oro High School! Although we are beginning our academic year virtually, we are all hoping to return safely to the classroom in the near future. 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 (and coaching) 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 Grandsons, hiking in the Catalina Mountains and volunteering with the Rotary Club and Junior League.

I hope you find the contents of this site helpful. Google classroom will be updated several times weekly with the addition of assignments and resources for students and parents. Please encourage your student to sign in to google classroom, using the codes specific to their class.

It is a great day to be a Dorado!
