Mrs. Ann Mathieson

I was a product of Decatur Public Schools and have been in the district since 1985.  I taught 3rd-6th grade at Southeast and Oak Grove.  For 7 years, I coordinated the New Teacher Mentor Program and supported the new teachers with full time mentors, resources and training.  For the past 10 years, I have been an administrator and have loved seeing our students grow!  

I live in Decatur, Illinois and am married with two grown boys. My husband and I both graduated from MacArthur and Millikin.  My husband went on to graduate with his masters from University of Illinois and is enjoying retirement.   My oldest is a math teacher at MacArthur and my youngest is a nursing student at Millikin.

I am thrilled to be a part of this district and the Montessori Academy! For the past 8 years, we have been growing, training and planning for our two Montessori schools to combine!  The remodeling of the old Thomas Jefferson is a collaborative effort between staff, students and familes of both Garfield and Enterprise.  We can't wait for you to come visit our new facility and see our kids at work in their Montessori environment!
