Cristin Costello
Middle Group

Middle Group (Grades 2-3)

Cristin began teaching at Walden in 1993 in the Middle Group, and now focuses her teaching attention on the areas of math and science. She is absolutely thrilled to be part of the teaching collective and believes that a Walden education is one of the greatest gifts she can give to her son, now a Walden alumnus.

Cristin rejoined the Walden Foundation in 2004, having previously served between 1996 and 2000. She is delighted to serve on the Foundation because it sits directly at the crossroads of history and progress. As a board member she uses her communication and organizational skills to support the school specifically in the areas of personnel policies and professional training. Cristin received a bachelor of science from Smith College in 1985 and a multiple subject credential from San Francisco State University in 1992.
