Ms. Kelly was a professional rock for us!

We found ourselves in an unimaginable situation with criminal charges pressed against my husband relating to a firearm. We were both petrified. Especially with the gun climate we find ourselves in. Neither of us had ever been in trouble with the law and after a terrible accident, we found just that. Ms. Kelly is extremely professional and knowledgeable of the legal system. She took the time to explain everything to us and prepare us for what would follow.

We are happy with the outcome of the case and would highly recommend Ms. Kelly to anyone who may find themselves in our situation.

Highly Recommended

First of all, I would like to thank Colleen Kelley and all the staff at Wolf Law for helping me greatly with my legal matters. I called and was able to get consulted that same day, and the prices are very manageable. Colleen did an awesome job and took her time reviewing all the evidence and negotiating with the DA. In my first case she was able to get the charges completely dismissed, which was very impressive. I had a second case where she got me a deferred judgment deal, which was great considering the charges pending. I am very pleased with her efforts and time spent working on my case. Again, I would highly recommend Wolf Law, giving them 5/5 stars!

Thanks!

Dear Ms Kelly you have truly been a blessing to me.When this situation took place I searched and searched for a qualified attorney to represent me in fighting for my life att after att turned me towards wolf law and I told myself I wanted the best and she clearly overachieved. After doing so much for me and my family I felt I need to compensate her for what I feel was going the extra mile and she insisted that what I’ve paid was enough. That kind of integrity and dedication to your clients says a lot about wolf law. I will always be indebted to you guys thanks for everything.

Jeffrey Wolf is Everything You Could Hope for in a Defense Attorney

When a tragic situation affected our family, we immediately contacted Jeffery Wolf. We were comforted knowing that we had a knowledgeable, communicative and compassionate attorney on our side. He often answered our calls after-hours and always stayed with us after court appearances to answer all our questions. During busy times, he would be sure to send a quick note letting us know when he would get back to us and never left us wondering if he had received our inquiries. Beyond being confident that we had the best representation possible, we also knew that Jeffery really cared about us and in fact, he became an honorary member of our family. He was open and honest with us and the DA in order to come up with the best, most fair agreement. We were never left wondering what was going on or what was going to happen. We knew that Jeffery would fight for us as hard and for as long as it took. It felt wonderful knowing that we had Jeffery in our corner. Hopefully we will never need his services again, but if we do, he will be our first call. We highly recommend Jeffery Wolf for anyone who needs a lawyer and wants the best.

— Jenni DeWitt Walker

The Best!

Jeff is very professional, knowledgeable, and as good of a lawyer as there is. I had a restraining order full of false allegations, and Jeff got everything dismissed. Even though it was a restraining order, Jeff treated my case as important as any other case. Thanks, Jeff!

Wolf Fought Hard and I Owe Him for All He Did

I am writing this letter to show how much I appreciate Mr. Jeff Wolf for representing me in my DUI case. When I first visited Mr. Wolf I had all these questions of what is going to happen in the case and to myself. I did have a prior DUI in another state so this was new to me.

I received my DUI in April and finished my court in September. During this time Mr. Wolf had an open door policy if you wanted to visit or maybe answer any questions that I may have had. His personal attention to my case made me feel at ease at all my court appearances.

Mr. Wolf guided me through all the steps that were taking place around my case and all his advice paid off when the day came for my sentencing. Actually, the judge was impressed with all the steps I was doing to remedy my terrible mistake. Mr. Wolf fought hard for me and I owe him for all that he did for my family and myself. I can honestly say that I have found a gentleman that I would recommend to another or help my family with any issues.

I Was Lucky to Have Jeff Represent Me

After a referral from a friend, I was lucky enough to have Jeff represent me in a domestic violence case. I found Jeff to be extremely professional and experienced in his field. This being my first experience with the court system, he took the time to explain the process and my options in terms I could understand. I never felt like he was forcing me to take one option over another, he clearly explained each one and, while giving his recommendation, left it up to me as to which decision I felt would be the best for me and my family.

I am very pleased with the outcome of my case and would highly recommend Jeff to anyone in this situation.

Wolf Law Saved My Career

I’m a college student in a highly prestigious nursing school. After a night of drinking, my now ex-girlfriend and I got into a heated argument that landed me with domestic violence charges. I thought my career was over and the tens of thousands of dollars I spent on multiple years of school were all for nothing. However, Mr. Wolf was able to get two of my three charges dismissed altogether (one of them being the most serious) without us even walking into the courtroom. When we got to court, he was able to get me a deferred sentence–the best possible scenario. All in all, Wolf Law is hands-down the best in the Denver area. They are the reason I can still pursue my career goals.
