Clients Say

  • Great Attorney

    I was kind of nervous at first as the courts recommended him but after I met him I knew he was the right attorney. He was amazing, very laid back but knew what he was doing and he believes in his work. I am very happy he was my attorney, I highly recommend him to anybody who needs a fantastic lawyer.


  • Appeal Attorney

    I had to file an appeal, due to several mistakes made with my original defense team. I was appointed Attorney Mann. We spoke several times, he listened, he read my documents, and we met months later in court. He is the best lawyer, also, honest! It’s hard to find an honest defense attorney. He is, he will be up front, and he found many mistakes that I had not. With his hard work, I was awarded a year off of supervision. That meant the world to me. I would not recommend any other attorney in Wisconsin for any reason. He will go above and beyond, help explain everything, especially important when you’re scared. My family and I will be forever grateful. Thank you Attorney Mann.


  • A trustworthy partner for your legal needs

    When I got into a bit of a jam last summer, Jeff was my first call. Jeff is very well educated and what impressed me most was his process. Jeff is very approachable and easy to talk to, especially about the difficult situations that require his expertise. Any time I needed to contact him, Jeff would be quick to respond. He was also able to calm my nerves both by providing great advice and anecdotal experience, and by being well informed about the “players” within the legal system in the Fox Valley. Jeff made a number of calls to get my case moving forward and was there for me whenever I had questions or concerns or anxiety in working through the legal system. I cannot stress enough how important I feel it is to have someone that feels like a partner in working through legal matters. Having Jeff, a confident and experienced lawyer, represent me and counsel me on my case has made the whole ordeal much more manageable and much less stressful.


  • Amazing Attorney!!

    Jeff Mann has been my attorney multiple times. I got myself into a few situations and he is the first and only attorney I considered calling. He is very thorough and was there to come see me right away when I was placed in jail. He is very well educated and trust his knowledge of the courts. He works hard for you and fights for you from the start to end. I feel like I wouldn’t be where I am right now if it wasn’t for Jeff Mann. I was charged with repeater drug charges and facing revocation/prison time. Jeff Mann fought hard to get me into Drug and Alcohol Treatment Court and with his efforts I was accepted. I couldn’t even explain how his efforts and persistence saved my life and saved me from being revoked or going to prison. I’m over a year clean and should graduate Drug and Alcohol Treatment Court in Jan 2017. I would and have recommended Jeff Mann to anyone with legal issues no matter what your situation he will fight hard for you. He is more than an attorney he actually genuinely cares about you and your outcome.
