THEO GRAYSON, Adolescent Director
Theo joins Mountainside Montessori as a certified Montessori adolescent teacher who has been a head middle school teacher and athletic director at Washington Montessori School in CT. She has over 30 years of teaching experience, including North Country School in Lake Placid, NY, a farm and garden school, Greenwood School in Putney, VT, which is a school for boys with learning challenges, and South Kent School in CT, where she headed the ELL (English Language Learners) program and leaning support program, before teaching for thirteen years at Washington Montessori.
She is passionate about Montessori philosophy and fully embraces student-centered education, where adolescents are responsible for their learning and have the opportunity to engage in meaningful work that allows them to explore and connect with their place in the world. Adolescence is a time of change, passion, exploration, and independence. Theo finds this an exciting time of life for students to harness their energy and focus on what is meaningful to them, while giving them a strong foundation beyond their teenage years to ultimately contribute to the world in positive and healthy ways. At WMS she developed the Hero’s Journey program, based on Joseph Campbell’s work, to provide students an opportunity to explore who they feel they are, who they want to be, and how to purposefully work toward developing that person. Theo believes we learn the most about ourselves when we are stretched, growing the most when we are pushed out of our comfort zone. Life’s challenges are opportunities to discover who we are and discover the choices we have in moments of hardship to become who we want to be. Adolescence is a delicate and exciting time of life.
Theo and her family live on her family farm in Upperville. She is an avid runner, outdoors person, and has competed extensively in running races, two seven-day multi-sport adventure races, and the TransRockieRun, a six-day, 130 miles race along the Continental Divide in Colorado. Theo enjoys animal husbandry and has been involved in various aspects of farming throughout her life. Traveling is another passion, and she spent semesters in Nepal and Indonesia during college. In recent years, she has traveled to Costa Rica and Nicaragua with her teenage children.

ALICE CATLIN, Upper Elementary Guide & Mentor
Alice grew up in New England, spending a lot of time outdoors camping, swimming, riding bicycles, hiking, and skiing with her family. She still loves the outdoors and has added gardening to her repertoire.

She holds two Master’s Degrees in Education, one with an emphasis in Montessori and one in Special Education. She received her Association Montessori International (AMI) Elementary diploma in 1995 and taught at that level for almost ten years after which she was the Elementary and Adolescent Coordinator for a large Montessori school in the Boston area. She became an Elementary Consultant for AMI in 2009 and consults at the national level. When she and her husband decided to move back to Virginia, she took the NAMTA Orientation to Adolescent Studies and taught adolescent students on a farm for over six years (similar to the wonderful farm Mountainside students are privileged to be on). Working with adolescents reinforced her elementary experience and gave her a deeper understanding of the value of Montessori education.

The next year she got her AMI Elementary Montessori diploma in Mexico City, and taught for a year in a lower elementary classroom.

Cate is very excited to get back into the classroom and become part of the Mountainside community!
A Virginia local, Corey grew up and has spent most of his life in the Shenandoah Valley. He feels a special connection to the mountains and finds an excuse to explore the Blue Ridge whenever he can. Corey was raised in a tight-knit family in Harrisonburg and still loves to spend time with his five siblings, niece, and four nephews. His experience helping his niece and nephews grow was a major inspiration for his journey into early childhood education. After trying traditional childcare for a few years, he found Montessori and never looked back. The intentional, methodical, and respectful nature of the Montessori Method called to him and he left his role as an Assistant Guide to pursue an AMI certification. Now finished with training, Corey is eager to continue the Montessori tradition with a new Prepared Environment and a new generation of joyful young minds. Montessori believed children are the greatest instruments of change in our world, and Corey’s life goal is to guide the children in his care toward their highest potential.
