Our Teachers

The teachers at ESNS are passionate about play-based learning, social-emotional development, and culturally sensitive teaching. They model collaboration and friendship in the ESNS community every day.

Karen Welser

Karen graduated from Swarthmore College, where she majored in English. She has been a member of the East Side Nursery School community since 2001, when the first of her four children began in the Tuesday/Thursday class, and has been teaching at ESNS since 2016.

Children and education have been long standing passions for Karen: she is certified in Parent and Family Coaching; she currently leads an online international adoption support group; and has previously developed, written, and taught an original religious education curriculum for children ages 3-9. Karen and her husband live near ESNS on the East Side, with one child in elementary school, one in high school, one in college, and one in graduate school.
