Alison (Ali) Sullivan joined the LCMCS community in 2016 as the assistant in the Wy’East classroom. She eagerly moved across the country in August 2016 from Chicago to Portland for her position at LCMCS. Ali worked as the assistant in Wy’East for two years and enjoyed teaching art and science electives when not assisting in Wy’East. In the 2018-2019 academic year, Ali completed her AMI Elementary Diploma through Montessori Northwest in tandem with a Masters of Education from Loyola University Maryland. Ali also holds an undergraduate degree in environmental geoscience. When Ali began teaching in 2014, she realized her passion was exploring the natural world through the eyes of her students.
