We chose Mr. Hagen after a quick search for a emergency chips case! We called his office at 445 pm and he personally answered and took our case! Tom was very thorough and very well prepared for each court appearance as well as phone conferences! His expertise and compassion for his work is remarkable! He made my family feel like we were important to him and not just another case! He is professional in every way ! I would recommend him to anyone that needs a good attorney on their side! Thanks Tom for everything!

Mr. Hagen communicated with me throughout the duration of my case and provided me legal aid up until my last court date and beyond. I would highly recommend him to anyone in need of a great attorney.

Great Representation!
Tom represented me in a really messy traffic violation. He was so knowledgeable and his staff was very helpful. I could not have asked for a better outcome.

My boyfriend got into a fight a while back and got himself into trouble! He didn't start the fight but he held up his end. Mr. Hagen helped us through the mess and his assistant Miss Jill kept us informed about everything along the way. Hope we don't need him again but if we do, Tom Hagen will be the one to call.

Very good Lawyer
Thomas helped get through a very difficult situation with my DUI. His knowledge of the law and his past experience is undoubtedly, without question, superb. His professionalism is tops. After describing my case to him, his confidence and reassuring comments to me, calmed my biggest fears and helped me enormously. He was always there when questioned needed to be answered. And the staff at R&K are excellent and very professional. In my case, the police did not have justification to initiate a stop. Therefore, my constitutional rights were violated and the case was dismissed on that premise. I'll never look for another lawyer again when it comes to defending the innocent. Thanks Tom for everything.

Best of the best
I contacted Tom Hagen with a DWI charge, refusal to test, and three other misdemeanors, 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 expected. I was supposed to have lost my license for a year, but got it back right away, all charges were dropped besides the refusal. If you are looking for a good lawyer, I would highly recommend Mr. Hagen.

Gave me hope and leveled the field as a father who feels the system is skewed.
In dealing with my child support case, I was a perennial do it yourself kind of guy and received the results one can expect. I finally had to give in and allow a professional to handle my case. Tom and Diana were my first experience in hiring an attorney. They gave me such relief throughout. From clearly explaining the process, answering questions, and, most importantly, giving me a calm space to think and carry on with the other parts of life, they resolved the issue beautifully. In a more recent event, my ex was going to stand in the way of my son accompanying me on a trip she had previously given permission for him to take. It may seem like a small thing, but to a 14 year old who was looking forward to the vacation with his father, it was nearly impossible to comprehend. With a simple letter from Mr. Hagen, I now know he and I will have the memories from our upcoming trip that are sure to last a lifetime. I can't thank or recommend Tom Hagen and Diana Brauch highly enough. I no longer fear doing what it takes to stand up for my rights and those of my children. You'd be a fool not to have them on your side.

damn good
Attorny Hagen turned my career ending DUI charge into a careless driving. As he predicted the most likely outcome from the free consultation. Incredible lawyer and man, I cannot thank or recommend him enough.

Dope boy fresh
Tom isn't just a lawyer, he's a good guy and makes you feel comfortable in your stressful situation. And as for mine, he did a damn good job getting me out of a lot of garbage and I would recommend him to anyone as long as he's free the next time I do something stupid:)

Major help. Great attorney. Truly cares for your best interests
I contacted Tom Hagen with a legal problem. Tom always made me feel that he was the only one working on my case. The information has always been correct and what I was told to expect when in court. I would highly recommend Mr. Hagen.

Dismissed DWI
Tom saved my career! I was facing a DWI that had the potential to ruin my career. Tom put together a great case and had it dismissed! I didn't even know that was possible. I still have a my job and attribute that to Tom's hard work on my case.

Former DWI Client
I am so glad that I hired Tom Hagen for my DWI. Not only did I get a good outcome for my case, but I was always able to talk to him not an answering machine. You saved me from losing my job and for that I am so very thankful!

Relationship: Supervised lawyer
"I endorse this lawyer. I've been working with Tom for over a year and am constantly amazed at his ability to win criminal cases! In the past year I've sen him get many DWI's outright dismissed, which may sound normal, but I believe he may have the highest win rate of DWI's in Blue Earth County. I've also seen him with family law clients, he does not have as much experience in this area, but does a fantastic job of making their problems his problems. Keep up the good work Tom!
