My Key Issues

Urban planning and smart growth

We need a measured approach to balance the complex issues related to increasing density, housing affordability and greenspace preservation.

Community health and wellbeing

The physical and mental health and wellbeing of a community is a hallmark of a great place to live. Decatur should provide healthy living options for ages: 0-4, 5-12, teenagers and adults, including seniors.
