Tammy Oesting’s Biography

Tammy Oesting has spent the last 26 years delivering professional development workshops, consulting schools, and educating new Montessori teachers. Her passions include issues of social justice, educating support staff, life sciences, neuroscience as applied to educational practices, and exploring the magnificence of the world. She is location independent with her husband Aaron and serves Montessori globally through her company ClassrooMechanics and partnership in Principles to Practice.

After stepping foot into her first Montessori Classroom in 1994, Tammy gained her AMS credentials in 3-6 and 6-12 and has worked in most every role in a Montessori community from an assistant to classroom guide to school leadership. These experiences inform her consultation work with individuals, schools, and teacher education programs.

With her current work as a Field Consultant and Instructor for several Montessori training programs, her delivery of workshops and Keynote presentations as a speaker both nationally and globally, and evidenced by her articles published about a variety of topics within the field, Tammy is clearly passionate about Montessori.

In 2019, she was Interim Principal for a new Montessori school in Da Nang, and another in Ho Chi Minh City, Vietnam, and she co hosted the first Asian Montessori School Leadership Retreat with attendees from 7 countries.

In 2020, Tammy helped found Montessori Everywhere which celebrated Dr. Montessori’s 150th Birthday reaching 6K+ Montessorians in 121 countries. She also moderates several Montessori Facebook groups including Montessori Leadership (3.8K members), the Montessori Teacher Educators’ Guild, The Diverse Classroom: Cultivating Anti-Bias and Inclusivity, and The Male Montessorian.

In 2021, Tammy is producing and hosting Chip DeLorenzo and Dr. Jane Nelsen’s course Positive Discipline for Montessori Schools and Families. She is currently working towards her Masters of Montessori Integrated Learning through TIES to be completed in March of 2022.
