SHANNON FALLI LASSER, Assistant Head of School

Shannon grew up in the suburbs of New Jersey and New York. After receiving her BS in Biology from the University of New Hampshire, she discovered her love of the outdoors by way of her travels in Alaska and Colorado. After working in the non-profit sector for some time, she ultimately earned an MBA from Arizona State University and relocated to Virginia. A Montessori mother of two, Shannon joined the Mountainside staff in 2015. She is excited to offer assistance in whatever capacity is necessary to further the vision of Mountainside.


Josephine grew up in the suburbs of Baltimore, Maryland.  She has always enjoyed the idea of school, playing teacher at home as a young child, honing her cursive skills, and reading to her younger siblings.  A senior project in high school solidified her interest in pursuing Education as a college major.  Josephine graduated from The University of Richmond with a B.A. in Early Education and taught 3rd grade for three years in Chesterfield County, VA.  In the hopes that she could better serve children who were struggling in school, Josephine returned to school to earn her M.Ed in Special Education from the University of Virginia.  After teaching 3rd and 4th grades for several years in Prince William County, VA, Josephine again returned to school at the recommendation of a colleague familiar with the Montessori pedagogy and received her AMI Primary training from Washington Montessori Institute.  The training not only inspired and affirmed her views on early childhood education, but has guided her life since.  All three of her children attended Montessori schools during their Primary, Elementary, and Adolescent years, with her oldest a member of Mountainside’s first Primary class in 2004 and her youngest a graduate of the Adolescent program in 2018.  Although her children are now attending high school and college, Josephine is happy to remain at Mountainside where she truly feels she’s found a home.

 LAINE ITEN, Director of Development

Laine is originally from Hampton Roads and comes to Fauquier by way of Charlottesville where she made her home for nearly two decades. She is a graduate of the University of Virginia with a Bachelor of the Arts in English Literature and Studio Art. She has personally experienced the impact of the Montessori method, with two young daughters who are busy, smart, self-assured, and thriving in Mountainside’s Primary Program.

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.

ANGUS GOLDBERG, Humanities Instructor

Dr. Angus E. Goldberg was born and raised in Alaska, where he attended open-educational schools throughout elementary school and high school.  He has deep roots in this area, however, having grown up spending summers at his grandfather’s farm just up the road in Orlean.  His undergraduate studies at Wesleyan University included religious studies and classical civilization. An abiding interest in the past led him to Scotland, and the University of St. Andrews, just up the road from the farm that belonged to his other grandparents.  While there, he earned a master’s certificate in maritime studies before completing a doctorate in modern history at the same institution.  Dr. Goldberg believes that historical awareness is a prerequisite for culturally literate and responsible citizens, and he relishes the opportunity to assist his students as they pursue their their exploration of the past in all of its myriad forms.  He is a baseball fan, and an authority on the history of dogs at sea, which affection for sea rovers reflects his own interest in various topics pertaining to social history.

Kristina was born and raised in Joplin, Missouri. Her mother is a traditional teacher and her father is a microbiologist. Her parents encouraged Kristina to explore the outdoors and work on her grandmother’s farm in the country. Kristina’s fondest memories were spending time in her father’s lab looking through the microscope and chasing the cows on the farm. Her parents also encouraged her to explore the world to gain life experiences.

An opportunity led Kristina to teach when her two older children were younger. She lived and worked for the Department of Defense Schools in Azores, Portugal, Japan, and Hawaii. She studied Early Childhood and Elementary Education at Drexel University. Kristina’s journey led her to Virginia to teach in a Montessori School in Springfield, VA, as a Primary Assistant. She knew this was her path to take. Kristina took her Infant/Toddler Training through Central Guided Montessori (MACTE) in 2015. She looks forward to furthering her knowledge in AMI and obtaining her credentials this coming year.

The first three years of life serve as a critical foundation for development. Kristina’s mission is to encourage independence, respect for self and the community, and the exploration of what our world has to offer.

Currently, Kristina’s family lives in Harpers Ferry, WV. She is a proud mother of three beautiful children. Her eldest son has chosen to serve our country, her daughter is going to study stone masonry and historical restoration, and her youngest son will continue his Montessori education at Mountainside where his curiosity and love of learning will be encouraged.

UNYONG KIM, Lower Elementary Assistant

Unyong Kim is Korean-American, having emigrated in 1962 to London with her family where she Twisted and Shouted to the Beatles as a little girl and ate tea and biscuits.  They then moved to Arlington, Virginia in 1964 during the Civil Rights era, where they stood out as immigrants and racial minorities, no matter their British accents.  She has learned much about how people can connect across identities of all kinds and her work as an adult has taken her in front of wide variety of  groups, including school children, for training in prejudice reduction and conflict resolution.  Her study of Tibetan Buddhist meditation during an Masters program in Contemplative Psychology at Naropa University in Boulder, CO, has helped her with teaching mindfulness, yoga, stress management and leadership skills for living in flow.  She has taught Stress Burner Yoga since 2001, her senior students continue to teach in Falls Church, and she now offers classes via video-conference.  She has traveled widely overland on all but two continents, has pushed herself to run a marathon to learn what it takes to do something that extreme (once was enough for her!), and met and married her spouse.  The space and beauty of the region inspired them to move from Arlington to Marshall in 2012, with their three daughters, now 21, 18 and 12.  Her interest in Mountainside Montessori grew each time she drove past and saw trees being planted and animals munching in the fields.  With two college age girls and one fast-approaching, she is excited to have steady work with the interesting team at Mountainside, learning the Montessori method for partnering with children’s natural desire to grow and learn.
