Stephanie Clark


School Director

Stephanie (photo: middle) begins her 8th year as Director of HPMS and her 22nd 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.

Sarah discovered HPMS while working as a nanny for two girls who were attending the school. The more Sarah became acquainted with the staff, the method, and the children, the more she wanted HPMS to be a part of her own child’s life. When Sarah was three months pregnant with her daughter, Sarah put her on the waiting list to enroll at HPMS. In 2004, Sarah’s daughter began HPMS, and Sarah joined the school community as a volunteer.


Before joining HPMS, Sarah was a nanny for ten years. In 2006, after volunteering for several years, she joined the HPMS staff as an Assistant. She soon became the Afternoon Care Guide. In 2014, Sarah took on her current role of Toddler Community Guide.

Ivy Vang

Toddler Community Assistant

What brought me to HPMS was how different it was compared to my experiences working in other childcare settings. Before HPMS, I had worked at two other centers that followed curriculums very different from Montessori. I was drawn to HPMS because of the school environment, the curriculum, the teachers, and the children. There seems to be a deep understanding and respect for the independence of children. They are learning for themselves while we guide them as teachers. 


I currently have a diploma for Early Childhood Education from Saint Paul College, and have recently gotten my certificate in Assistance to Infancy through the AMI 0-3 Orientation Course.

Some of my hobbies include singing, reading, cooking, playing video games, and creating art. I also come from a big family of 10, being the second eldest, so I have been caring for children from a young age. 

Nanette Nagel

Afternoon Program Guide

Nanette is in her fourth year as the Afternoon Program Guide. Nanette has been learning about, and working with, young children most of her life. She has worked in Montessori environments, at a children's farm school, and as a toddler teacher before joining our staff in 2014.


As the Afternoon Program Guide, Nanette has created a warm and beautiful environment in which children can explore arts and crafts, a library, building blocks, puzzles, games and cards, trains, and practical life activities. The children learn songs to sing and songs to sign. She provides a loving and nurturing environment for the children in her care. 


Nanette earned her AMI Assistants Training Certificate in 2005. Nanette holds a bachelors degree in Sociology and Criminal Justice and, before, was a Saint Paul Police Officer for eight years. 


Nanette loves cooking, gardening, and flea marketing.
