The Waupun School superintendent says she will be leaving district with mixed emotions. Dr. Tonya Olson is stepping down at the end of the school year after accepting a job to be principal at Belleville Elementary School. Olson says its closer to where her husband works as a school superintendent. During her six year term Olson says she is proud of many accomplishments, including a successful $36 million building referendum. Olson says she is also proud of the SAGES Charter School in Fox Lake. The school board will hire a search firm to begin the process of finding a new superintendent.
