"The entire team at Kohlmeyer Hagen did an outstanding job of helping our family! We are so grateful for the NOT GUILTY verdict that they achieved. Tom, Steven, and Shelly worked endless hours. Truly the best lawyers around!"
Thank You Again, Jason, Shelly, Gail!
"Jason, Shelly, and Gail did an excellent job in my complicated farm divorce . The opposing councils tried multiple tricks and bulling but Jason Kohlmeyer wouldn’t allow such tactics. I absolutely would recommend them if your in a divorce situation. And they’re good personable people that takes a bad situation and puts your mind at ease while they deal with the ugly issues. Thank-you again, Jason, Shelly & Gail!"
"Big City" Quality with Small Town Values!
"Everyone will need a good lawyer sooner or later, and I for one am so thankful to have had Kohlmeyer-Hagen in my corner when I needed them. Outstanding service, professional approach, and tremendous results were what I expected (it is what I was paying for, after all). What I didn't expect was how Jason and Tom and the entire team really cared about me and my family on a personal level. Thanks a million guys."
Jason, Shelly and staff do SUPERB work!
"They are efficient, knowledgeable, caring, professional, and very enjoyable to work with! I would recommend Jason as an attorney without a doubt! He was great to work with, and he was able to get me the results I had wanted! Thank you for an excellent job done!"
Completely Satisfied with the Outcome of My Case.
"This law firm is very experienced, very effective, and yet very personable when interacting with me throughout my nerve-wracking legal process. I would hire the Kohlmeyer and Hagen Law Firm again without hesitation. And, I have since recommended them to several friends and acquaintances."
I Can't Thank Them Enough!
"I can’t speak highly enough of Mr. Kohlmeyer and his legal assistant Shelly. I felt like they gave my case the attention and time it needed, they were very responsive and honest with me the whole way through. I can’t thank them enough in getting me through one of the most difficult times of my life!"
