Staff - Muzzy - greenhouse2017-352.jpg

Carol Muzzy, Dean of Grammar & Logic

Mrs. Muzzy attributes her curiosity and love of history to her father, Thomas M. Burton. Growing up, she cannot remember a time when he was not taking a history course. Throughout the years of homeschooling her six children, and now some of her twelve grandchildren, history and historical fiction were always the core of her curriculum. When the opportunity came to teach Grammar level History and Literature, it was a natural fit for her. She taught from 2009 to 2017. She began serving as Dean in the summer of 2017. Carol married Ken in 1973. They are members of Church of the Resurrection in Wheaton.
