My name is Ruth Dearth and I am so excited to be joining the first grade team for my first year at Walnut Street. I graduated from Simpson College in 2017 with a bachelors degree in elementary education and liberal arts, and endorsements in reading and language arts. Outside of school I enjoy cooking, drinking coffee, spending time with my family, friends, and dogs, and coaching cheerleading at Lincoln High School.

Teaching Experience

I have been a teacher since 2015. I have been teaching at Walnut Street School since 2015.


I enjoy spending time with my husband, especially going to the library together. We have been married since the summer of 2015.

I also enjoy hanging out with my family; I have 15 siblings, and 10 of them are Chinese-American. This is part of why I love Walnut Street so much. The connection to Chinese culture and language is wonderful.

I have been teaching and learning from kids since I graduated from Iowa State University in 1996. I taught in Houston from 1996-1998. My family and I moved back home to Des Moines at that time when the first of four of our children was born--we realized we still needed our own parents after all! I’m so glad we made that choice because it was shortly after that in 1999, I joined Des Moines Public Schools, where I taught at McKinley Elementary. During that time I pursued and achieved a Masters Degree from Drake University in Educational Leadership.  My continued love of learning new things and having new adventures led me to Walnut Street School in 2014. I am blessed to be part of another DMPS family!

When I am not at school I am involved with family activities and creating projects and crafting things for the classroom and for my home.
