About me

Our firm handles both litigation and intellectual property matters. My practice focuses on providing clients with professional, persistent, aggressive representation in the areas of civil and criminal litigation.  My extensive and successful trial experience has resulted in substantial personal injury verdicts and settlements, as well as acquittals and dismissals for those accused of crime --from the most serious offenses (first degree intentional homicide) to drunk driving and traffic offenses. My background as a municipal judge, prosecutor, and trial lawyer for more than 35 years gives me a unique perspective, and the ability to focus on obtaining the best possible results for our clients.

  • Chad Hendricks

    While Chuck's experience speaks for itself, there is nothing he can't help you with. Chuck is not only one of the finest attorneys I know, he is an incredible person. He is always willing to help no matter what the issue is, and if he doesn't know the answer (rarely happens) he will make sure you speak to someone who does know. I highly endorse Attorney Blumenfield. Anyone would be incredibly lucky to have him as their lawyer.

  • Peter R. Heyne

    Attorney Blumenfield has for years organized an annual conference in recent developments in Wisconsin criminal defense law. I attended two such conferences while in law school; they were top notch. Further, Atty. Blumenfield is a very active and knowledgeable participant in the statewide criminal defense listserv. If you need criminal defense in the Milwaukee area and beyond, contact him!
