Hi, I'm Mike and I was born to serve!

Helping people, building community, and economic opportunity are in my DNA.


Rapid City and the Black Hills are changing, and I want to contribute to the economic growth and dynamic opportunities of our region. 


It is an honor and privilege to continue representing District 34 in the SD State Legislature.


I’m excited by the potential to make a brighter future for this wonderful place we call home.
