Absolutely unparalleled!
From my initial consult to follow ups post final divorce date, Atty Zimmerman had my best interest in mind. She actually listened to my concerns, thoroughly explained all of the working parts, asked me for input, and overall put me at ease about and throughout the entire process. I was undoubtedly in the best and most trustworthy hands and am so grateful to have had her represent me during one of the most difficult times.

Child placement change
Following my divorce the child placement we originally had planned was not working out. My son was having a difficult time in school and showing signs of neglect. I reached out to Mari and after what I felt was my long and complex history, without skipping a beat said lets do this. My ex represented himself as pro-se (mainly because he didn't want to fork out the money for a lawyer) but this also gave us the opportunity to utilize mediation to the fullest potential - because lets be honest who wants to go to court and represent themselves with zero knowledge in law. So Mari took that opportunity and worked with myself making sure I was taken care of, but also informed my ex what things would look like pending on how things went. While any process with kids is difficult Mari made it a little less difficult. She would answer my emails in a timely manner, answer my random questions that would come up along the way, and prepared me for every step of the way. She educated about all the laws, rules, and regulations that were out there and while overwhelming at times, it was important to know and I appreciated her taking the time to explain those to me. Her support staff was also wonderful. So overall, if you are looking for someone who will listen to your story, prepare you, be honest with you, and truly work with you for the best possible outcome, Mari's it.

Mari Zimmermann and law team are very professional and know their stuff! Mari prepared us for what to expect in our custody battle and was always two steps ahead of the other party involved. She listened to our wants and needs in our case and was always very honest with us. Mari was available and responsive to all of our questions. We won our case with Mari when other lawyers we consultanted said it would be a long shot. Very happy with Mari and the outcome of our case.

"The path of least resistance"
When I first met Mari, this was the phrase she used and it stuck with me ... "The path of least resistance". Not a phrase you might hear from a lawyer, especially when hiring a lawyer is all about bettering your odds to "win". But let's face it, divorce, and court in general, is unhealthy and unnatural. Anything you can do to make it less painful is appreciated! While I could tell right away Mari would fight for me like a dog on a bone and certainly had the knowledge and the wherewithal to do so, she also understood that my ex-husband and I had thus far never hired a lawyer for our disputes, not even for the initial divorce. Everything was done amicably on our own. However at this 7- year mark we have reached an impasse on certain subjects and I needed to get professional help. Mari came highly recommended from a trusted friend. She instantly made me feel like she was my biggest fan and my advocate. After she looked over my paperwork we had a brief discussion and then she basically did what I call "read my mail". That means she has the ability to read a lot into the situation very intellectually but very precisely without even knowing all the details. She was spot-on! She wrote things down for me, helped me with the wording for documents I needed to write, communicated with me a few times in person and many times over email. Within a few weeks we developed a plan, and executed it and in the long run my ex-husband had to give up alot... but I think he actually felt empowered that he was part of the decision because all of the decisions made sense! Mari is wicked smart when it comes to the law... but she's also "street smart", compassionate, determined, and honest. I would encourage anyone who is on the fence about hiring a lawyer to meet with Mari Zimmermann. It will bring all the insight and direction you are looking for!

Great attorney and person!
Mari was on top of everything with my divorce. I always thought it was a long tedious process but she moved swiftly and kept me in the loop with anything happening. She responded to emails and calls really quickly. The best thing about Mari is her genuine and caring personality. She really did her best to make sure I was ok!

Wonderful, ethical, and sharp
I've been very impressed with Mari's commitment to her clients as well as her ability to see the big picture. She is invested in doing the right thing and gives credibility to her profession. Many divorce attorneys give their field a bad name. She is a credit to an area of law that is known to be very contentious. Above all, Mari is a good person.

Wonderful legal representation when going through a divorce
Mari made what was a painful experience bearable. She lead me through the intimidating and scary process of divorce with wisdom, guidance and top notch legal support. She always made herself available to answer my questions and talk me through the complicated and confusing legal system as it pertains to divorce. My children were and are always first in every choice and decision I make, Mari and everyone at Zimmermann Law Office put that first as well. I highly recommend Mari if you are in need of legal representation, you will not be disappointed.

My attorney , Mari Zimmermann, was not only knowledgeable and skillful, she was also kind and so professional. She was always accessible to me and willing to explain every process we went to help me weigh my options when a decision needed to be made as to what course of action should be taken. I felt my outcome was all I could ask for. I am very grateful for Mari's expertise and praise her to the moon! My highest recommendation for Mari to anyone who needs a great attorney.

Mari was completely professional and thorough. She knew my case and the judge very well. She seen what was best for my daughter and acted accordingly. She was on time for court. She really did a good job. She answered all my questions and let me know the whole situation. She went through everything with me even if it was a situation that could go bad. I would pick her every time. I highly recommend her.

Smart, Skilled, Sympathetic
Mari Zimmermann was recommended to me several years ago. I found her to be a huge relief amidst a very trying time. She skillfully mixed her extreme intelligence with a sympathetic heart. She responded in a timely fashion, she listened and answered questions clearly, and she took the weight from my shoulders onto her own. I will always be grateful for this. She is someone I highly recommend.

My Little Fire Ball
The only issue I had with Mari is communication on how things were progressing with my case or getting back to me on issues. I never worked with a lawyer before and didn't know what to expect. She did a great job!

Young, but conscientious attorney
Ms. Zimmermann was not the lead attorney in my case, however she was instrumental in brief writing, research, and trial preparation for me. She is very detail oriented and methodical in her research, and is able to interpret legalese in a way that was understandable. I found Ms. Zimmermann to be very professional, ethical, and responsive. She truly cares about the outcome of your case, and will do everything in her power to get you the best outcome - while being direct and honest with what you can expect.

It was unfortunate that she did not come prepared. I had set everything up, gave as much information for her to assist me in my case. She charged me a lot of money, but never showed results. For the amount of time my case lasted, and the amount of time she claims she spent working on my case, it didnt add up.

Terrible Attorney-Wouldn't ever recomend her to anyone!!
Charged me thousands of dollars to prepare for a court date. When we got in there all of her preparations were useless. Very inexperienced Was not familiar with my case at all. I was embarrassed to be her client. Also did not pronounce my name correctly once in the court room. Horrific experience....
