Stephanie Clark


School Director

Stephanie (photo: middle) begins her 10th year as Director of HPMS and her 24th year with close ties to the school. She earned her Association Montessori Internationale (AMI) Primary Diploma from the Montessori Center of Minnesota and her M.Ed. from Loyola University in Maryland in 2005-06. Stephanie earned her Bachelor of Arts Degree from

Macalester College in 1988.

Like Daralyn and Sarah, Stephanie began her Montessori journey as a parent. The amazing experience her oldest son had at the school was enough to change the course of her own life. While her second son attended HPMS, Stephanie worked as an Assistant at the school and then took the primary training. Before returning “home” to HPMS, Stephanie worked as a Guide in three Montessori schools (with long commutes!) across the Twin Cities.

It is with deep appreciation for Wendy Warren, who taught and lead HPMS for over 35 years (and is our beloved sub-Guide), that Stephanie takes on her role at HPMS.
