Mrs. Mary St. Clair

I attended Plano schools from 1st grade through 12th grade, and graduated from Plano Senior High School. I attended the University of North Texas and earned a Bachelor’s degree in Interdisciplinary Studies, and I have a Master’s degree in Administrative Leadership. This is my 18th year in education, and in Plano ISD. I have taught kindergarten, first grade and was an instructional specialist. I have been married for 22 years to my wonderful husband. We have two children. In my spare time, I love going on walks with our dog, Racer, and going to the movies. I'm looking forward to another great year!
