THEO  GRAYSON, Adolescent Guide

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.

JULIANNE DAVIS, Adolescent Guide

Julianne is a native Californian who calls Santa Barbara her west coast home. Growing up there, she loved to hike along the ocean and in the surrounding mountains, appreciating and being revitalized by nature. She put herself through college to finish her Bachelor’s degree in Film Studies at the University of California, Santa Barbara and eventually completed a Master’s degree in Organizational Management from Fielding Graduate University.

She had a foundational experience when she became a peer mentor in college, where she experienced the power of engaging change with others. After moving to Virginia and working as a project manager for nearly ten years, she became a certified personal coach. She uses the co-active model of coaching, a non-directive approach emphasizing that the coachee is creative and resourceful. While considering a career change to teaching, she worked for Loudoun County as a substitute teacher for two years and then took a break to have twins. In addition to spending time with her family, she loves to cook and garden.

Montessori first came to her attention when her younger sister, who had struggled in the public school system to the point that she hated school, began attending a Montessori program and changed from an unhappy student into one that loved learning. Julianne remembers thinking that school must be doing something right. After having her own children, she began learning more about Montessori and came to Mountainside by way of the Parent-Infant program. She is looking forward to continuing her learning journey in a setting where she can combine her passions for nature, learning, and coaching as an Adolescent Guide.
