Callie Colgan

Lower School

Callie is transitioning to our pre-kindergarten program as a homeroom teacher after being a classroom facilitator in the Lower School during the 2020-2021 school year. Before coming to Gilman, Callie opened and was the lead preschool teacher at The Highlandtown Preschool. Prior to that, she had a variety of early elementary teaching experience in Baltimore at Irvine Nature Center and Friends of Patterson Park. She is a graduate of Ohio University in Athens, Ohio and is currently working toward earning a Master of Arts in Teaching at Towson University. Her son, Otto, will be a new Greyhound in second grade this fall.
