Meet our Directors

Stephanie Yourdan, Director

I began my career in early childhood education as the Lead Teacher in the preschool room at one of West County Day School's sister schools and moved into administration 2 years later. I hold a master’s degree in education from UMSL, where my studies were focused on early childhood education, ESL,
positive behavior support, speech, and language development. I am also certified to teach in Missouri.

I have been a part of the West County Day School family since August 2014. I am certified to teach both early childhood and elementary education and have a bachelors in elementary education. Before joining WCDS, I served as a kindergarten and first grade teacher. I have a strong grasp on what “kindergarten readiness” really means. I enjoy my role as Assistant Director and love being a part of the family atmosphere here at WCDS.

I recently got married and much of my free time is spent with my husband, our son, Leo, and our adorable puppy, Penny.
