About us

Our Faculty

The Best Part of MAB:

Our faculty is the heart of this organization and by far our most important asset.  We’ve been together so long, it feels like we’re one big family. Our specialized training, combined experience and knowledge makes us experts in the field of child development. We all love what we do and we feel fortunate to be able to do it together. You wont find a team like this anywhere else!

Montessori Certified Teachers:

The Montessori method is complex and takes many years of experience to learn. In fact, all of our teachers will tell you that in spite of 20 years in the classroom, they are all still learning. Montessori certification is required in order to be a lead teacher at MAB. 

Montessori Certified Directors:​

Not all schools are led by Montessori certified adults.  All of our owners and management; Beth, Bart, Jill, Robin, Larry hold either AMS or AMI teacher certifications. We believe leadership is responsible for maintaining fidelity to authentic Montessori and upholding the shared philosophy and ideals of the faculty.  This can only be accomplished through consistent, high quality training in the unified Montessori method.

Belmont Greene Montessori Elementary

Assistant Teachers

Assistant teachers at Montessori Academy play a pivotal role in supporting students’ learning journeys, providing individualized guidance and fostering a nurturing classroom environment. Many of our classroom assistants hold the Montessori certification, adding even more consistency and authenticity to the environment.  


Classroom Support

Classroom support faculty are integral to our daily operations. They work with all the faculty and get to know every child in the building. Because they work each day in many different rooms, they must be versatile, patient, humble, hard-working and up for anything -and that’s exactly who they are!

An Extraordinary Team

Beth R. Theriot

Founder, Specialist

Beth has been involved with the Montessori community since 1971 as a parent, board member, fundraiser, event planner, substitute, and assistant teacher. She has been an AMS certified Montessori teacher since 1984, and the founder and head of school at Montessori Academy at Belmont Greene (MAB) since 2001. She brings to MAB extensive experience and a deep understanding of the Montessori philosophy and teaching methods. She has been able to attract a talented and gifted team of certified Montessori teachers who share her commitment to Montessori education and development. Beth recognizes that successful child development depends fundamentally on building a shared sense of Montessori family at the school, which can only be accomplished through effective and continuing communication with children, parents and faculty.

Beth is the director of the Northern Virginia Montessori Institute AMS affiliated teacher education program. This is the only one of its kind in Northern Virginia and one of only 3 in the entire state. Since 2007, our program has trained more than 150 new Montessori teachers, most of whom work in Loudoun and Fairfax Counties. In her role as director of both MAB and NVMI, Beth has helped significantly to set the standard for Montessori education in Virginia.

Beth’s professional career in Montessori is based on a Baccalaureate in Psychology from Loyola University, New Orleans, a Master’s Degree from George Washington University and Montessori certification from Virginia Commonwealth University. She also attended the academic phase of the lower elementary training in 2004.

Beth married Lawrence Theriot in 1970 and raised three successful young adults, all of whom completed Montessori primary school.
