Hired Law firm 2024I can’t say enough good things about Sean and his staff. I had a very messy divorce. I worked with another lawyer for seven months and he did very little for me except continually remind me that Wisconsin was a 50/50 state and that even though I brought significant assets into the marriage while my ex had, none, I earned about three times more during the marriage, and we were only married for a short time, I was going to have split everything 50/50 with him. He pressured me to agree to a very bad mediation deal. Luckily, before having the judge finalize the mediation agreement, I came across Sean‘s reviews on Google. I wasn’t just looking at how many stars he was given but I read what people wrote about him. People repeatedly commented on his commitment, his dedication, and going the extra mile. I made an appointment for a consultation with Sean. Within the first five minutes of our meeting, he said, “Let me show you what the law actually says, I have had to educate other counsel and judges about this.” He printed off the actual law where it states that Wisconsin is a 50/50 state after consideration is made for the following items, which included length of marriage, what each brought into the marriage, and the length of the marriage. After talking a little more, he asked why I didn’t have a restraining order and I told him that my previous lawyer told me it was 50/50 whether I would get it and that it would be inflammatory and work against me even though I felt very unsafe and threatened. Sean appeared very upset after hearing this, and disagreed, but continued to be professional and not bad mouth the other lawyer. Sean was very brave about taking on my case this late in the game with a fast approaching court date and so much information to take in. Also, my ex hired a lawyer who I had heard said is the best divorce lawyer in La Crosse. I wholeheartedly disagree, because Sean definitely is the best. I am still in awe of the commitment Sean made to helping me get a fair trial and a great outcome. I would see emails from him sent on weekends and in the middle of the nightat times. It was so reassuring to know he was on my side and so determined. He blocked out several days of his calendar so that he could familiarize himself with my huge stack of documents. As soon as I retained Sean as my attorney, I finally felt like I could relax and let him take care of it. I knew that no matter what happened with the results of the trial, I would be satisfied, because I had the best representation I could possibly have. My hearing went on for two days. Sean was relentless in his effort to get me a fair trial and justice. In the end, the judge decided to divide the assets 80/20 in my favor. I did not get everything I wanted, but that never happens in court. It was about $70,000 that Sean saved me based on what my previous attorney was forecasting with a trial outcome. In some ways, more importantly, Sean gave me the opportunity to tell my story and have it validated by the judge. He was so committed to making it clear that I tried so hard during the marriage and that my ex was dishonest and completely took advantage of me. It seemed that Sean felt a moral obligation to not let my ex take more from me and to have his greediness and dishonesty exposed. I will also say that his staff was very friendly and hard-working. Sean went out of his way to try to save me money when he could by having me do some of the legwork if I wanted. He kept me consistently updated on status and promptly responded to all of my messages. Hopefully I will never need counsel again, but if I did, I would definitely retain Sean again. If it were possible to give him 10 stars, I would.

How do I choose a lawyer?
Consider the following:
- Comfort Level – Are you comfortable telling the lawyer personal information? Does the lawyer seem interested in solving your problem?
- Credentials – How long has the lawyer been in practice? Has the lawyer worked on other cases similar to yours?
- Cost – How are the lawyer's fees structured — hourly or flat fee? Can the lawyer estimate the cost of your case?
- City – Is the lawyer's office conveniently located?
Not sure what questions to ask a lawyer?
Here are a few to get you started:
- How long have you been in practice?
- How many cases like mine have you handled?
- How often do you settle cases out of court?
- What are your fees and costs?
- What are the next steps?
Want to check lawyer discipline?
It is always a good idea to research your lawyer prior to hiring. Every state has a disciplinary organization that monitors attorneys, their licenses, and consumer complaints. By researching lawyer discipline you can:
- Ensure the attorney is currently licensed to practice in your state
- Gain an understanding of his or her historical disciplinary record, if any.
- Determine the seriousness of complaints/issues which could range from late bar fees to more serious issues requiring disciplinary action.
