About me

I represent people who are injured by the negligence of another. I attended law school at the University of Wisconsin in Madison and graduated in 2002.  My lovely wife teaches math in a public school and is amazing.  We have a daughter and a son (due May 2015).  We love them more than life itself.  It sounds cliche', but it's absolutely true.  Everything I do in work and life, I try to do in a way that would make them proud.  When counseling a client, I advise that client the same way I would my own family.  That is the method I use to best fulfill the oath I took before the Wisconsin Supreme Court as an attorney.

I represent people who have been injured by the negligence of others, though I spent the initial years of my career working for insurance companies, so I know how both sides approach these cases.  It allows me to approach the value of a case from both the best-case and worse-case scenarios, and balance them appropriately. This knowledge, and my familiarity with settlement and jury ranges for similar cases, allows me to approximate how a jury might view your case. That is the key to getting the fair value for my clients.  If I think the best course is to settle your case, I will tell you that. If I think trying your case is a path worth taking, I will tell you that as well.

If you have been injured through no fault of your own, and have required medical care for your injuries, feel free to contact me for assistance.  There is no charge and no obligation for an initial consultation, and I will be happy to give you my honest impressions.  Keep in mind that the value of a personal injury case is difficult or impossible to ascertain early on, and in some cases it is impossible before you are done treating, or at some kind of healing plateau.  The most important evidence will come from you, and sometimes more importantly your physician and your medical history.

In cases with extraordinary objective injuries, determining value is sometimes, unfortunately for the injured, much simpler. 

Please contact me, and I am happy to discuss your potential case at no charge.
