Corey G. Mehlos

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 office.

Why Choose Corey Mehlos?

Attorney 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 for three semesters, handling 10 post-conviction homicide and assault cases. With the Innocence Project, Attorney Mehlos learned advanced DNA testing theory while working with Dr. Greg Hampikian, one of the nation’s leading DNA experts. Attorney Mehlos’ relentless investigation in a case was the driving factor in his client being released from prison 26 years before his scheduled release date despite three prior attorneys being unable to achieve that result.

Attorney Mehlos recently presented on Drug Recognition Expert cases at the 2017 Wisconsin Drunk Driving Seminar.  Attorney Mehlos has never lost a Drug Recognition Expert (“DRE”) case as all of his cases have either been dismissed or reduced to a reckless driving offense, which is not a crime and avoids an operating while impaired conviction.  His presentation highlighted strategies he has used to win cases involving the opinions of self-labeled “Drug Recognition Experts,” including using studies that demonstrate how DRE opinions that an arrested driver has a certain category of drugs in his or her body based on a method that is scientifically invalid and uses self-created scoring charts that double-blind studies have proven falsely inflate the accuracy of DRE predictions and hide the fact that officers are only 32 percent accurate at predicting the presence of certain drug categories.  Attorney Mehlos’ presentation also highlighted successful strategies he has used to demonstrate that DREs opinion that a driver is impaired by a drug or prescription medication is scientifically flawed, fails to account for essential factors including medical diagnoses and prescription medication history, and involves a highly subjective and scientifically unreliable process that has been rejected by national experts in pharmacodynamics, pharmacokinetics, and opthamology and has never been validated by the scientific community.

Prior to joining Kaehne, Cottle, Pasquale & Associates, S.C., Attorney Mehlos practiced law in Wisconsin in the areas of criminal defense, personal injury, family law, municipal law, trust and estates, and commercial transactions. He has won difficult cases that have allowed clients to be reunited with their families after months of legal separation, proven the innocence of a man facing three years in prison and extended supervision, and succeeded in protecting the rights of community members in a lawsuit against a multi-million dollar corporation, the first case he tried as a lawyer.  He has won numerous criminal trials involving complex defenses, and has been invited to speak at Wisconsin’s Annual Drunk Driving Seminar on defeating cases involving Drug Recognition Experts.  Attorney Mehlos’ philosophy involves putting in extremely long hours, working collaboratively with members of the Kaehne, Cottle, Pasquale & Associates, S.C. law firm to achieve the best results, and being responsive to his client’s anxieties about their cases.

  • 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.
