Never go into a Courtroom Alone!

Drunk Driving, Criminal Defense
and Personal Injury Law AttorneyCorey G Mehlos

Attorney and Counselor at Law, practicing in our Sheboygan , Appleton, and Fox Cities offices.

Why Choose Corey Mehlos?

Attorney Corey Mehlos graduated with honors from the University of Notre Dame and the University of Wisconsin Law School. During law school, Attorney Mehlos participated in the Wisconsin Innocence Project, handling numerous homicide and other serious criminal cases. Attorney Mehlos learned advanced DNA analysis litigation strategies while working with leading national experts in DNA, such as Dr. Greg Hampikian, and his innovative legal strategies and relentless work on behalf of the client was instrumental in successfully vacating a conviction of an Innocence Project client, resulting in the client walking out of prison 26 years prior to his release date.

Attorney Mehlos’s philosophy emphasizes building a strong personal relationship with his clients and their families, creative problem-solving, and relentless advocacy.  His clients consistently tell him they appreciate how much he cares about them and their case, meeting with them on weekends or working until after midnight to prepare for a trial, if necessary.  Attorney Mehlos tailors his strategy to each client’s case by working as a team with the client to master the facts of the case, consulting experts, and working relentlessly with the firm’s criminal defense team until the client achieves the best possible results.

In his first case as a lawyer, Attorney Mehlos successfully sued a mutli-million dollar corporation. Since then, Attorney Mehlos has practiced law in every region in the State of Wisconsin, including the Eastern District of Wisconsin Federal District Court, winning numerous challenging trials, and consistently achieving outstanding results for even the most complex cases, such as persuading prosecutors to dismiss homicide cases.

Atty. Mehlos’s achievements have not gone unnoticed by his peers.  As a result of his extremely high success rate and complex strategies for Drug Recognition Experts (“DRE”) cases, he was special guest presenter at the Wisconsin’s Annual Drunk Driving Seminar on strategies to attack cases involving DRE’s and drugged driving defense. Attorney Mehlos does not shy away from difficult cases, as he and his fellow members of Kaehne, Cottle, Pasquale & Associates, S.C. are determined to reach the goals set by both he and his clients.  After winning a trial involving particularly steep odds, a colleague told Attorney Mehlos: “You have such grit and determination. A strong never-say-die attitude. 99 of 100 lawyers would say plead. But persist you did. And likely stunned the courtroom.”

Attorney Mehlos has been recognized by his peers as a Super Lawyer- Rising Star, a distinction reserved for less than 2.5 percent of lawyers in Wisconsin. Attorney Mehlos currently serves on the Executive Board for the Wisconsin Association of Criminal Defense Lawyers, presented at Wisconsin’s Annual Drunk Driving Seminar, and has been featured on C-SPAN and ESPN.

Attorney Mehlos lives in Ozaukee County with his wife, Katherine. In his free time, he enjoys traveling, Irish culture, and spending time with his friends and relatives.

  • My son had a very serious charge being made against him and Corey went above and beyond anything we couldn’t even thought about! He always called to check in on how not only my son but also how his father and I were doing too. Corey was in contact with other lawyers to get a little extra input to make our case even stronger and with the attention to not only the major, but also the small details that others wouldn’t have worried about, Corey spent a lot of time on. He was able to not only have that charge dismissed, but reached an agreement that my son was ok with! I truly believe if not for the time and patience of Corey, my son’s life would’ve been ruined! So, I would and have told everyone I know that if any legal issues were to come up, Corey IS the best person to hand on your team!
  • I cannot say enough great things about Attorney Corey Mehlos! He really listened to our situation and we could feel that he really cared. We went into his office so upset and confused, but by the time we left, we felt so much better and more at ease. He has a way of explaining things that anyone can understand & he makes sure you do understand. He answers all and any questions in such a timely matter as well. He is one excellent attorney that I would recommend with no hesitation. He is also very respectful, honest and down to earth. He is an all around excellent attorney!!!
  • After looking around for an attorney while facing 5 felony charges I felt comfortable in his abilities after talking to him about my case. I am glad I did because Corey ended up negotiating a total of 17 felony charges for me. With his time and effort, I walked away with no felony charges. Some people would call that a miracle but I would say that is an excellent attorney working hard for his client.Furthermore, he really cared about me. I consider him a friend.
    Thanks Corey.

Our Results

Find out what our trial-tested defender can achieve.

Beyond Expectations

My husband had never been in any legal trouble before and we didn’t know what to do or what the process was. Attorney Kaehne was very upfront and willing to explain every step of the way. My husband can be very skeptical when it comes to trusting people with his best interest, but Attorney Kaehne always remained professional and helpful. My husband was facing the possibility of years in prison and Attorney Kaehne was able to get the matter dismissed. He will always be our first choice!

The Outcome was Far Better than I Expected

Attorney Kaehne always communicated with me on what was going on and his plans for future court appearances. The outcome of the case was far more better than I expected and am really pleased that Chad did what he did to get this issue resolved.

Treated like Family

Amazing people as well as amazing attorneys. I was always treated like family.

Not Guilty Verdict

Attorney Corey Mehlos gave my case the upmost attention. He worked very hard and many long hours on it. I was impressed with his dedication and his understanding to my wishes. Not Guilty verdict at my jury trial. I highly recommend him.

In Good Hands

One of the best things about this firm is that they are truly advocates for you in every sense of the word. They listen, affirm, and explain everything without all the jargon that can so often times come with anything regarding the legal cases. I felt supported and knew I was in good hands.

Getting Responses at 9:00 pm at Night

The best lawyer you can hire for your case! Chad was extremely helpful and polite in answering all of my questions. I was even getting responses to my emails at 9 at night. He did a great job helping me get through the legal process. I recommend him to anyone needing a good lawyer.

Amaro is a very efficient attorney with extensive knowledge of the hispanic culture and language. He has a keen sense of justice and honesty. For the years I have know him he has proven to be a source of counsel. His clients will find his humble and cordial demeanor, appealing and refreshing. This is why I would recommend Amaro to everyone looking for legal advice.

From my experience, Attorney Kelsi Cottle has been an over-the-top attorney. She keeps me apprised of my case, has answered my questions, and treats me with respect. She has been very efficient, handles things expediently, and I feel I am represented by a very sharp attorney who has my best interest in mind.
