Annie Boyarkaro,  Bluebell Assistant Teacher

  • B.A. in Psychology, Education, and Child Development: Marlboro College, Vermont.
  • Waldorf Teacher Training, Kindergarten and Early Childhood: Sound Circle Center, Seattle, WA.

Annie grew up in Colorado, and after living in Vermont for five years, returned home in 2015 to be closer to her growing family. Annie discovered Waldorf education while she was studying early childhood education and child development. Her initial exploration of Waldorf education developed into her thesis, which focused on the importance of play in child development. It also became a lifelong interest, transforming  her understanding of young children, and of education itself.

She began teaching at a small Waldorf Nursery and Kindergarten in Southern Vermont, first as an assistant and aftercare teacher, and then as a lead Kindergarten teacher in her final year. After her initial experiences teaching young children in Head Start programs and public schools, she was deeply impressed by the respect given to children – not only in the reverent way they were spoken to and treated, but also in the great effort made to honor the whole child in their individual growth, within an environment that encourages self-initated learning.

After six years within Waldorf Early Childhood education, she continues to cherish the foundational ideals of protecting an unhurried childhood full of imagination and wonder, providing the young child the freedom to play and to learn actively, to explore the natural world and nourish the senses, and to be nurtured in a loving space that feels like a home.  As she continues the calling as a Waldorf early educator, she appreciates the emphasis on continual self-development, the consideration of a teacher’s own inner work. In the endeavor to be worthy of imitation, she  has found a wonderful incentive for personal growth. She strives to model through her presence as a teacher, and bring her best to the children and to her work each day. Annie enjoys writing, photography, and traveling.

Seeking a better life near Milwaukee, they cultivated the land, grew their own food, sewed and knitted clothing, started a shoe business in the home (grandfather was a cobbler) and took care of animals all while raising children. Heidi grew up experiencing the world as safe and good, where she was given the freedom to be a child while observing and participating in activities around the home and farm, and where there were daily opportunities for uninterrupted play in the neighborhood, garden, and out in nature.  It is this rich cultural setting that instilled in Heidi a life long passion to work with children and to provide them with some of these same experiences.

Heidi recently came to Boulder with her family from a beautiful and rich farming community in Viroqua, Wisconsin where for ten years she was lead teacher in a mixed-age Waldorf Kindergarten (3-6 years old) that emphasized outdoor play, offered an all organic hot lunch program, and daily movement.  Her kindergarten was modeled after the insights of Helle Heckman, founder of Nokken in Copenhagen, Denmark where children ages 1–6 spend a good part of their day outside and playing in the forest.  Prior to her Waldorf experience, Heidi taught for ten years in public school kindergartens in Milwaukee’s inner city as well as in rural Door County, Wisconsin.  She earned a B.A. in Early Childhood/Exceptional Educational Needs from Cardinal Stritch College and completed a Waldorf training at Sophia’s Hearth Training Center in Keene, New Hampshire, known internationally as the only professional development course program of its kind for early childhood professionals.

Martina Simunek-Suarez, Teacher at Shepherd Valley Waldorf SchoolMartina Simunek-Suarez, Sixth and Seventh Grade Teacher

According to Martina, her life has been a little bit as Bohemian as her name sounds. She was born in a small town in Lower Austria. Her mother's family were World War II refugees from Serbia, and since they had been uprooted, they leaned even more on their German traditions, Catholic faith and conservative beliefs. Her father was from Bohemia where there was much more liberalism and much less religion. On top of that, her father had grown up in a steel town in one of the socialist strongholds of Austria. So Martina moved back and forth between these two worlds. One might think that she ended up all confused, but she really liked it.

When Martina entered the University of Graz, she continued with a good mix of interests: starting with English and Russian, then adding Geography and eventually ending up in the Vietnam War Literature Collection at CSU in Fort Collins. There she met Julian, and while continuing to travel and work in Europe and various parts of the U.S., they started a family. They and their two boys, Markus and Matthaeus, all love the mountains. They hike, camp, fish and ski. Martina loves to read and also enjoys painting, tiling, carpentry work, electrical work, plumbing, gardening, and a bunch of other fun hands-on things, preferably with power tools. Martina was first introduced to the Waldorf philosophy years ago by her cousin, who, just like Rudolf Steiner and Martina herself, grew up in a little town in Lower Austria. After a whirlwind year back in good old Europe, teaching at the Freie Waldorfschule Wien West, Martina is back with some new ideas!
