I contacted Tom Hagen for a DWI charge, I was extremely impressed with Mr. Hagen, he knows his stuff, he's patient and made sure that I understood what was going on. He set me up with an amazing plea agreement and helped me out more than I was expecting. If you are looking for a good lawyer, I would highly recommend looking into this office.

Alexis U, DWI Client

This law office was very helpful and informative on helping me complete a settlement with my previous employer. Every time I called or emailed I was responded very promptly that same day. I also never felt pushed aside or that my case didn't matter, considering my case was small in comparison. I was highly recommended to them and will be giving the same recommendations.
