Hi! My name is Mary Ann Plenys and I am a Preschool Assistant here at St Leonard School. I
graduated from The University of Illinois at Chicago. I have been a member of the St. Leonard Parish for
thirty years. I am married and have two grown children. Both of my children graduated from St. Leonard
School, continued their education at Catholic high schools and earned their college degrees. As a parent
I was involved with both of our Cub Scout and Girl Scout Programs as well as the Parent Association. I
like to stay active and I especially enjoy gardening and visiting our beautiful National Parks. I began
subbing and tutoring at St. Leonard in 1999. This is my seventh year as a Preschool Assistant. I love
helping our children learn while having fun.
