Hi!  I’m Ms. Retterer, Welcome to 4th grade. This is my thirteenth year teaching here at Old Post Elementary. I was born and raised in the Oswego School District (Long Beach, Thompson, and OHS), and graduated from North Central College, Naperville, IL in 2001.  My interests revolve around my career and my family.  I especially enjoy reading, rollerskating, and spending time outdoors.
