Mrs. Sierra Marchand

Hello, my name is Sierra Marchand. I am the Assistant Swim & Dive Coach at Prosper High School, as well as a US History teacher. While I am a Frisco ISD alumni, I couldn't be more excited to be starting my 4th year of teaching for Prosper ISD. I have also served as an educator in Utah County, The International School of Utah, and Dallas ISD. I attended Brigham Young University, where I received a BA in History Teaching. I am proud to be a Prosper Eagle and look forward to the upcoming school year. On this website you will find information pertaining to my U.S. History classes.
