Our Board Members

The idea for Heartwood Montessori School began in 2013 when neighbors and Montessori parents, Sarah and Sinead, were longing for a quality Montessori program in Northeast Minneapolis.  They knew of many parents (including themselves) who were driving their children out of our neighborhood to find high quality Montessori environments, and that did not feel right.  Since that first idea, Sarah and Sinead took the time to thoughtfully plan out all the information they would need to start a non-profit school.

In February of 2014, Sarah and Sinead held their first informational meeting about creating a board for this new Northeast Montessori school.  The founding board of Heartwood was formed by a group of passionate parents and community members.  Together they logged over 3,000 hours of volunteer hours and raised over $21,000 to launch the school in September of 2015.

Our governing board is now composed of hard working, dedicated parents, community members and Montessori professionals who continue to guide the school towards the mission and vision set forth by the founding board members.  

AJ_Bio_PicAJ NIEHAUS   President
AJ has lived in the Waite Park neighborhood of Northeast Minneapolis since 2009 with her husband. They have two daughters with one attending Heartwood and one waiting to begin. AJ was drawn to a Montessori education for her children because of the freedom, creativity, independence, and ability to work at one’s level that the Montessori theory fosters. AJ owns SANscript, and automated publishing company, with her mother. She holds a BS and MFA in performance and technology, where her thesis was in wearable computing and smart fabrics. When not running after her small children or working, she loves to knit, read, and create. AJ was drawn to joining the Heartwood board because she believes Northeast needs a stellar Montessori option that is open to any child.


Keenan 2-sq

Sareen is a resident of the Logan Park neighborhood. She currently works for the United Way and was previously a Career and Technical Education grant writer and manager for Minneapolis Community and Technical College. Sareen keeps busy with her family – husband, Brendan, and four daughters: Brigid, Aubrey, Roisin, and Johanna, plus her mother, Kate, and sister, Rachel. Sareen’s least favorite thing to do is sit on the couch with nothing to do, so she always has a full schedule. When she is not volunteering for Heartwood, you can find her volunteering for other organizations such as St. Paul Adaptive Recreation, Second Harvest Heartland, St. Paul Intercultural Institute, and the SciMathMN board of directors. She enjoys playing softball and broomball, visiting museums (or events) weekly, riding bikes, camping, cooking, gardening, canning, and brewing — all with family, of course.
