Her professional experience also includes child-care directing, preschool teaching, parent education, and training adults in the field.

Sheri resides in Elkhart, Indiana—though she is a Michigander through and through! She enjoys writing and reading poetry, visiting historic sites and landmarks, watching really good movies, and spending time with family!

 

**Jeannine Ernst, Staff Trainer**
