  • During the course of his career, Mike has had the opportunity to argue many cases before the Wisconsin Court of Appeals and the Wisconsin Supreme Court. Mike’s efforts in those cases often clarified Wisconsin law and in some cases, his efforts were responsible for changing the law entirely. Early on in Mike’s career, he represented a young motorcyclist who was seriously injured when a motorist turned in front of him. The motorist was uninsured. Mike’s client had no insurance on the motorcycle he was riding but he did have uninsured motorist insurance on a different vehicle he owned. The insurance company argued that there was no coverage for the motorcyclist’s damages because of an exclusion in the policy. Mike argued that the exclusion was contrary to the uninsured motorist statute and that it also violated public policy. He argued to the Wisconsin Supreme Court that that uninsured motorist coverage should follow the person and not just the vehicle. This case changed the law in the State of Wisconsin for injured people, allowing for much broader coverage. Bauer v. Securities Mutual Ins. Co., 99 Wis. 2d 332, 298 N.W. 2d 58 (1980).Another case Mike handled that got state wide attention involved the Wisconsin Dog Bite statute and the liability of a “harborer” of a dog as opposed to a dog owner. Mike’s client was on her daily walk when someone let two large dogs out a door and they attacked Mike’s client. The dogs’ owner let them out but he was uninsured. He had been staying, though, with a friend and Mike sued the homeowner- friend arguing that she was a “harborer” under Wisconsin’s statute and thus a “statutory owner,” making her own homeowner’s policy liable for the loss. Ultimately, the Wisconsin Supreme Court agreed with Mike. Pawlowski v. American Family/Seefeldt, 2009 WI 105.

I was in a car accident which resulted in an injured shoulder and bicep. The next day I contacted Mike Siddall, a highly respected lawyer in the Fox Valley. From the very first consultation to our last encounter, he and his team were extremely thorough, making sure to understand each detail that could be relevant to the case. Mike demonstrated candor, determination, and a passion for his clients, which only the very few possess. I highly recommend Mike and his team to anyone seeking an experienced lawyer in his area of expertise.


I am so thankful I hired Mike as my attorney. Anytime my case comes up in a conversation, I tell everyone about him and the care and attention Mike and his staff put in my case. Mike is extremely knowledgeable.


Mike represented me for a motorcycle accident I was in. Mike was always very professional. If I didn’t understand something, he would explain it in terms I could understand. I always felt he was looking out for my best interest. If I had a question, he was prompt in returning the call.


Mike represented me in an auto accident in which I got hit from behind. Mike was able to answer all my questions so I fully understood what was happening with my case. Mike worked really hard to win this case for me.


I hired Mike regarding my slip and fall personal injury case. Mike and his paralegal Jessica were great! They always kept me informed, were so easy to work with, and very experienced. They kept me at ease during this difficult time and I’m so grateful for their help!
