In Her Own Words
"When I took my seat as Chairwoman of the board in December 2018, I pledged to listen to understand, debate respectfully, and seek common ground. By building relationships and working toward consensus, we will move beyond politics and focus on what Lake County residents deserve — a government that works to improve the quality of life of its residents."
