Mrs. Julie Kerstetter

Welcome to PreAp Geometry at Reagan High School!  A little information on myself.  I was born in St. Francis, Kansas and was the daughter of two high school teachers.  I inherited my love of teaching mathematics from my mother who was my high school math teacher.  After graduating from high school, I went on to Dodge City Community College and then on to West Texas A & M (West Texas State University) to graduate with a Bachelors of Science Degree in teaching mathematics and PE.  I played college basketball and then decided to stay and continue coaching at West Texas A & M as an assistant coach until 1989. 

I then moved to Perryton, TX for one year and then on to Garden City, KS where I married my husband, Devin.   I taught and coached at Holcomb High School for seven years.  During this time, I had three children, Drew, Megan and Derek and decided to become a stay at home mom for a number of years.  We then moved to San Antonio, TX in June of 2002, and I began substituting for the local schools.  In August of 2005, I started teaching at Hardy Oak Elementary School and then eventually moved to Reagan High School in August of 2010 where I have been since that time. I love teaching and I love kids, so I have the perfect job!
