Dr. Jefferie Thielbar

I graduated from the University of Wyoming with a Masters Degree from the College of Health Sciences.  I was a graduate assistant and specialized in Psycho-Motor Development having worked both at the University and at the Colorado Springs Olympic Training Center.  I started teaching Biology in Wyoming and taught for 10 years before getting my principal certificate from Chadron State College.  I also served as a high school principal in both Wyoming and Alaska then received my doctorate degree in Education Leadership from the University of Wyoming in 2010, at the ripe old age of 50.  So far, I have been teaching science for 16 years, been a high school principal for 10 years and a school superintendent for 3 years.  This year is my 30th year in education.  This is my 4th year at Plano ISD and I love it here.
