Laura Sternik

Faculty Member: Second Grade Teacher

Laura Sternik was born in Colorado, but spent much of her childhood growing up in hotels in Austria and Lebanon. At eighteen she moved to London to study Art and stayed there for seven years exploring many different artistic and esoteric subjects through the many alternative schools popping up in the seventies. It was only when her three children reached school age that she decided that none of the public schools in her area (Marin) were satisfactory, and she came across the Waldorf school. It was love at first sight, and soon she was involved in helping at the school. Serendipitously, during a move up to Seattle, she was asked to teach German at their Waldorf school, and a whole new path unfolded for her. She started her Steiner teacher training there and then completed it back in England. Laura was a class teacher at the Brighton Steiner School and Michael Hall Steiner School for 12 years before returning to the States to be closer to her family. Every year of teaching brings a renewed joy and wonder at how marvelously well the curriculum in our schools meets the children’s needs. She is also constantly amazed by how much there is still to learn and how happy that makes her.
