About me

For nearly 20 years, I have aggressively defended OWI and criminal cases throughout Wisconsin.  My practice is statewide, focusing solely on drunk driving, criminal and traffic defense.  Over the last 18 years, I have successfully defended hundreds of OWI cases. I have been the lead attorney on more than 150 OWI jury trials.   

Prior to working in Wisconsin, I was a law clerk for the Nebraska Department of Motor Vehicles.  My job was to assist in implementing the OWI implied consent law in Nebraska, and I worked with the administrative law judges in conducting administrative OWI hearings. 

My years of experience practicing in Wisconsin and my former law clerk experience have given me a unique perspective from both sides of the aisle.  I fully understand the necessity of having  the represenation of a qualified attorney in an OWI case.
