When assisting in a Montessori classroom, training is crucial. An assistant needs to know about Montessori philosophy and how the materials work in general. Tammy delivers comprehensive and engaging training to assistants making Montessori classrooms high functioning. As an assistant, I enjoyed observing all those little ones working with such concentration!

As an instructor, Tammy's teaching method is instrumental, thoughtful, captivating, and thorough in both her approach and instruction. To this day one of my favorite years in my classroom was teaching with an assistant/intern that took Tammy's Assistant Training.
