Katherine Denison - Board Member

Katherine’s pathway to Montessori took awhile. Katherine decided early on that animals were way more interesting than peers, so her education veered towards veterinary science in 7th grade. Katherine received a degree in animal physiology. For the following decade, she worked with the animals at Fred Hutchinson Cancer Research Center, cared for and bred endangered waterfowl at a ranch by Lake Stevens, and cared for waterfowl at the Woodlawn Park Zoo. Between these animal-focused jobs she had two children. When Katherine’s oldest turned four she was enrolled in the closest available school; Crown Hill Montessori. Katherine didn’t even tour it, she simply signed up on the phone. This was her official introduction to Montessori. Katherine started helping the school at lunchtime, eating with the kids while the teachers took a break. She became passionate about developing practical life work for home and even at the preschool. Katherine then decided to become a Montessori Teacher. She trained in Kent the same year as Gail and interned at Crown Hill. Katherine received a position at Discovery Montessori and worked there for 3 years before starting her own preschool, Veranda Montessori. She enjoyed that for 26 years and retired in 2022.

Anne Heil

Anne has been working with young children for more than 30 years in both Montessori and traditional schools in the US, Venezuela, Nigeria, and El Salvador.  Montessori education drew her in with its emphasis on peace and holistic education.  Then Anne fell in love with teaching when she observed a child's joy at her first realization that letters and sounds unlocked the door to reading. She continues to believe that Montessori's vision of the development of children on their path to adulthood has been proven timeless and is even more important now in our chaotic world.
 

John Heil

He has worked with students in environmental research and restoration projects, believing that when children and adults work outdoors, their observation and interaction in a natural setting gives them a better sense of themselves and a connection to the global community. Their focus is on a peaceful world for children and environments and communities that meet their needs – physically, emotionally and socially.
