Dmitria has many years teaching experience with all ages, in Spanish, ESL, and Montessori. She received her BA in Environmental Studies, her MA in Teaching, and is AMI trained at the Elementary level. Her perspective is rooted in being a twin, playing violin, five seasons as a Wilderness Ranger in the Sierra Nevadas, her work on a Farm in the Guatemalan highlands, and cross country travels. Her son, Bodie, joins the school as well, with many veteran staff knowing him since birth.

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.
