"My goal is to assure that all persons charged with a drunk driving or criminal offense have the opportunity to be represented by a qualified, competent and experienced attorney."

- Walter A. Piel Jr.

Years of Dedication

Since 1994, I have aggressively defended OWI and criminal cases throughout Wisconsin. My practice is statewide, focusing solely on drunk driving, criminal and traffic defense. I have successfully defended hundreds of OWI cases. I have been the lead attorney on more than 350 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 representation of a qualified attorney in an OWI case.

Being arrested for an OWI can not only be stressful but confusing as well. Paperwork and deadlines aren't always easy to understand and making sense of the court process can be difficult. Our FAQ section answers some common questions you may have before we have an opportunity to speak.


Client Testimonials

"Walter was everything I could ask for during one of the darkest periods of my life. He was compassionate yet realistic regarding my situation.
He explained every step of the process in ways that I could understand, took nothing for granted, and wound up getting the charges dismissed.
I could not have imagined a better outcome or overall experience.
Thanks, Walter, you saved the day!  "

"Walter Piel was my attorney and represented me with an aggressive no quit attitude. He took charge and never misrepresented what
he was willing to do or could do for my situation.
I was blessed to have him for an attorney."

"I just wanted to say thank you for guiding me through this whole ordeal.
I think it turned out well considering what I was facing. You were always very patient with all my questions and I felt like I could call with
anything that was not clear for me. ​"​

"Attorney Piel handled my case in a professional and expeditious manner.  
I was very satisfied with his representation of me and completely resolved my case.  It was great to have an attorney who truly “advocated” for me.
 In a time of need, Attorney Piel was there for me and on my side!" 

"I was involved in a car accident after I had been drinking. The police charged me with two felonies. Walt came to my house and drove all the way across two counties to sit at my kitchen table and hear my story about that night. He made no promises, but I could hear a very strong, solid, reliable, honest, trustworthy, experienced man sitting
in front of me speaking. I immediately retained his services.
That was the best decision I ever made."
