She returns to Myrtle Farm this fall, team teaching in the morning and full day programs. Adrienne first came to the school as an intern in 2007, and earned her American Montessori Society Early Childhood teaching certificate from Saint Mary’s College in 2008. She graduated from Ithaca College with a degree in Cinema and Photography. Jennifer Williams holds a BA in Child Development with a minor in Psychology from CSU Chico. She received her Montessori Pre-Primary certification from the S.F./ Bay Area Montessori Teacher Education Center in 1995. She has been team teaching at Myrtle Farm in the morning program since 2007. She lives in Concord with her husband and two daughters. Hadas Trost joins the Myrtle Farm staff as an intern this year. With three years of early childhood education and a preschool teaching degree from The Kibbutzim College of Education and The Wingate Institute in Israel, she is currently studying at the Montessori Institute of Advanced Studies in Castro Valley towards her Montessori teaching certificate. Hadas was born and raised in a collective community, called a Kibbutz, where kids take part in everyday activities, much like in Montessori. After graduating, she taught preschool until her family moved to the Bay Area in 1999. She has been working as a teacher’s assistant for the past three years. In her free time she loves to read books, work in her garden, and spend time with her family and friends.
