In 2004, Darlene, along with her husband Ken and their three daughters made their home in the Village of Mukwonago. Darlene's journey into public service began when she joined a newly created neighborhood block watch group, which inspired her to run for public office as a Mukwonago Village Trustee in 2008.

In late 2015, Darlene saw an opportunity to expand her service when she learned that the Waukesha County Supervisor for the 25th District was not seeking re-election. She decided to run for this office while also seeking re-election for her village trustee position. She has served in both capacities since 2016. Her commitment to public service was recognized by being nominated for the nationwide "Elected Women of Excellence Award."

Darlene is an avid baker and enjoys spending time with family.
