Colleen Kelley, Esq.

Wolf Law Firm, LLC was not recommend to me by anyone, but as it turned out, was the best choice I could have made!

While searching for a lawyer for my two cases, a DUI and a trespassing felony, an understatement to say how scared I was! Wolf Law Firm caught my eye and, truthfully, it was because their firm provided a free consultation, which is invaluable in and of itself. Colleen Kelley is the attorney that picked-up the phone that day. After talking with her, I made the choice to hire her as my attorney.

We got off to a rocky start, mainly because of my inability to realize just how severe my situation was. Then, one day, Colleen just laid it on the line for me, my obvious unwillingness to face what was happening and the fact I wasn’t facing my drinking issues. It was a conversation that she was bold enough to have with me. Thanking her a million times over isn’t enough for the fortitude she had that day, not only as my attorney, but as a person genuinely concerned.

OUR outcome was more than phenomenal thanks to her diligence! I am, and will always remain, emotionally indebted to Colleen for her courage, kindness and overall, being an awesome attorney.

The day I came across Wolf Law Firm was the day, as it turned out, my life has a new beginning.

Excellent Representation

After finding myself wrongfully accused of a DUI charge, Mr. Wolf fought to show the DA that I was not guilty and ultimately got the charge dismissed. Mr. Wolf’s knowledge, professionalism, and effectiveness made me feel comfortable and confident throughout my case. He was always more than willing to answer any questions I had promptly and thoroughly. Although this was an unfortunate situation, I couldn’t have asked for better representation. I would highly recommend Mr. Wolf!

A Light in the Darkness

Most people live their lives never dreaming they would ever need the services of a criminal defense attorney. But, sometimes, life takes a hard left turn with no warning and you can find yourself in a very dark and scary place. When that happened to us we didn’t know where to turn. But, our daughter did. An old classmate and friend, Jeffrey Wolf, was the person to call. So we did. We called an attorney but a hero was who showed up. Mr Wolf is a picture of competence with compassion. He alleviated many of our fears and answered every question with confidence. During this most difficult time he made it possible for us to continue to live our lives and actually sleep at night knowing that we were in the best possible hands. Our family will be forever grateful to Mr Wolf as he truly is a Light in the Darkness.

I Will Definitely Hire Mr. Wolf Again

I turned to Wolf Law for help after a small bumper ding in a Starbucks parking lot escalated once the Denver PD was involved. Jeff expertly stepped in to keep the matter from getting any more complex, including speaking with a Denver Police Officer who seemed intent on imposing the most severe charges possible. Jeff continued his zealous representation of my case in Traffic Court where he worked out a reduction in the ticket with the Denver City Attorney and also eloquently explained the situation and the facts at hand to the judge, resulting in a reduction in the fine. Wolf Law exceeded my expectations on this case and managed to keep me calm about the severity of the charges throughout the process. I would highly recommend Wolf Law to anyone and everyone, and if I ever have the need, I will definitely hire Mr. Wolf again.

Winning the Case

Colleen Kelley came through for me when I thought all else was lost. Colleen worked diligently and kept up the fight; she was able to get the job done, and I’m so appreciative for her work.

Excellent Attorney

We hired Jeff to take over my son’s case after our first attorney (from another firm) showed up to his first court date late, looking homeless, and worst of all, having absolutely no knowledge of the case. We hired Jeff who did an excellent job explaining the process and how to get the outcomes we were fighting for. My son was facing years in Jail and a class 2 felony on his record as a teenager. He was able to plead the case down to a deferred sentence with no jail time and in record time. The entire process took a little over 6 weeks. When we went to court for my son to accept his sentence, I could tell that a big reason Jeff gets the outcomes he does is due to his professionalism and good working relationships with his colleagues in the Justice system. Thank you, Jeff. I got my first good night’s sleep in a long time last night. I will be forever grateful to you. Thank you so much for helping my son keep his future in his control.

Excellent Representation!

Jeff was with me from Day 1 after getting pulled over for an accused DUI charge. Jeff’s knowledge of the process and responsiveness to my questions, concerns were impressive. His professionalism to me and in court was excellent. Jeff truly made this stressful and emotionally taxing situation 100 times better. I am grateful he was referred to me. I would definitely recommend Jeff if ever faced with a driving-related charge. Jeff will be my first call in the future for any legal counsel (which hopefully, is never again).

Hire A Lawyer You Can Relate To and Trust

I happened to find Jeff through a Google search for a DUI lawyer and I would have to say I really lucked out. I had heard horror stories about attorneys that overcharged their clients and that they would send others to represent them in court. From the initial phone call he helped me understand the process and prepared me for what was ahead. Having never needed a lawyer he was patient and made sure I understood everything before making any decisions. Jeff always made me feel like I was on the same level as him which I really appreciated. Jeff always prepared me for the worst, but in the end with his hard work and suggestions beforehand he managed to get me a pretty good deal. The best advice I could give is to be informed and START EVERYTHING right away. I would also say to hire a lawyer that you can relate to and that you trust. Don’t waste your money on someone that isn’t going to give you the personal attention you deserve. I would gladly recommend Jeff Wolf! He is down to earth and I never felt judged. He gave it to me straight and without hiring him I don’t know where I’d be. Thanks Jeff!

Look No Further – Jeff is the Best

I was falsely accused of a crime with serious consequences, was very depressed and got even more depressed and frustrated as I was interviewing attorneys to defend me. They had a broad spectrum of approaches and some were ready to head to trial immediately as it seemed they were primarily interested in battles and my money rather than my best interests. The first one was extremely arrogant and rushed to get me off the phone. My court appearance date was approaching and I was ready to give up when I came across Jeffrey’s website. I read he had once also been falsely accused which motivated him to become an attorney. After further reading, his philosophy appealed to me so I set up a free session.

I met with Jeffrey and told him what happened. He explained the alleged crime and potential consequences and then spoke about himself and his approach. I spent more time than the “free time” allocated but was never rushed. He listened, believed me and was really genuine as I had not witnessed before with other attorneys.

By the time we finished talking, I felt respected and not disrespected as I found out with this accusation, you are guilty until proven innocent from most everyone’s perspective. I hired Jeff on the spot and when I left his office, I felt this big burden lifted off my shoulders as I knew I could trust him to do his best for me. I was finally able to sleep that night and after several weeks able to put this out of my mind as being the constant main focus.

If you are seeking a very knowledgeable, trustworthy, caring, honest and respectful attorney, Jeffrey fits the bill. He is a great listener and never rushed me even with a flat fee rate. He has a good rapport with the Court who also respectfully listens to him. He is well spoken in the courtroom. I have seen him in several cases reaching very good settlements for his clients. On my case, he provided me his opinion with his rationale as to how I should proceed but allowed me to then make a decision as to go to trial or take a plea bargain. He would fully support my decision either way. Jeff is very good in providing the pros and cons, risks, and potential scenarios that may play out. My case will be dismissed shortly and record sealed as a result of Jeff’s hard work, negotiations, poking holes in the accuser’s story pre-trial, and dedication to my satisfactory case resolution. If you want the best, look no further as you have found him. Thank you Jeff!

Wolf Law is Well Worth the Investment

Thanks to Jeff Wolf I had the ideal outcome on my case, whereas without any representation it would’ve been a less than desirable outcome without me even fully knowing my options. He was extremely informative and thorough; it was clear that not only did he know what to do for every scenario but I was confident that he would make it happen, which he did. Very personable and easy to trust, I highly recommend Jeff and Wolf Law.
