Colleen Kelley is the Best

I have hired Colleen previously and she did wonders including case dismissal. The flat rate fee is such a wonderful carefree situation. I wouldn’t trust anyone else when it comes to felony legal matters.

— Dustin

Demonstrated a deep understanding of my specific legal issue

Mr. Wolf was exceptionally understanding and patient during a difficult time. His expertise, compassion, knowledge of the law, and support were invaluable. I would wholeheartedly recommend Mr. Wolf and his team.

Fantastic Attorney, Thorough and Knowledgeable

When I had charges pending against me, I had a free consultation with many attorneys and ultimately hired Jeff wolf as my formal representation. Most of the attorneys’ capabilities were relatively equal, but what stuck out with Jeff was his ethics and personal investment in my outcome.

From the beginning he tried to get a thorough sense of who I was in society and represent that to the judge for sentencing. In court he pleaded my case and balanced remorse for the action with any positive attributes to gain a favorable outcome. He is well spoken and respected in court.

I liked that his payment model worked through stages that he “earned” along the way. I had a clear understanding of what to expect from him, from the court, and the most likely requirements of my sentence. And when I didn’t understand or had additional questions on one part (and I had many) he took the time to explain and discuss the options and his recommendation with me.

He had a thorough knowledge of the system and its players as well as knowledge on unusual factors related to my specific case, and he made well-thought-out recommendations with reasoning but ultimately let me make the final decision.

The result of my case was quite favorable thanks to Jeff. Great lawyer, highly recommend.

One of the Best!

Absolutely the best!! Jeff and the team at Wolf Law successfully navigated me through one of the toughest and most stressful events of my life. From the 1st call to the last email, Jeff answered my questions, explained the laws and court procedures in terminology I could understand and kept me informed from start to finish. One of the best, case dismissed!!

I appreciated all of his help and the way he handled my case. I would highly recommend him to anyone who needs a good lawyer cause he’s definitely the way to go thank you again Jeff!

Jeff is a Powerhouse in the Courtroom

Jeff is truly an expert in his field. He is extremely knowledgeable and bright and it was clear throughout his management of my case that he is highly respected. He was very supportive of my desire to see my case through to trial, he was always empathetic, and he took the time to understand my personal and professional situation. He was determined to get me the best outcome with the least impact to my personal and professional life and he succeeded. We were dealing with a refusal and I have little doubt that I would not have had the same results with another attorney. Jeff is a powerhouse in the courtroom! I am beyond appreciative and would strongly recommend anyone facing challenging legal issues to seek out Jeff’s expertise.

— Jana S.

Highly Recommended!

Mr. Wolf is an incredible attorney to work with. My father and I have spent some time over the past 10 years with him, and have always seen fantastic results from different types of situations. He is very intelligent, honest, and diligent about any work brought his way.

I highly recommend Mr. Wolf and will call him first, anytime I need legal advice or representation!

Thank you Jeff!

So Glad I Hired Jeff Wolf for My DUI Case

I was originally considering not hiring an attorney since this was my first DUI offense but I’m definitely glad I did. It was my first DUI but I was involved in a one-car accident and totaled my car. I started to worry about the possible consequences after reading the penalties online. I contacted Jeff’s office after reading reviews on AVVO left by other clients. From the beginning he was very straightforward regarding possible penalties and possible outcomes, and gave me the details of what he would do if I hired him.

We worked out what strategies we would use for the DMV and Court. Without going into too much detail, I have to say that I was extremely happy that I decided to hire Jeff. Immediately after hiring him I felt a lot less stress about the whole situation. He was always in contact with me every step of the process and even did things for me that I didn’t have to do myself, like my DMV hearing.

Every DUI case is different based on many different circumstances, so I can’t say that my results will be yours, however I was extremely happy with my results. He won my DMV hearing, and I didn’t lose my license and got pretty much the minimum penalties in court. Overall, I would recommend him to any family or friends who find themselves in the same situation. I have several friends who had similar situations who couldn’t believe how lucky I was to get the outcome that I did. Thank you for everything Jeff!

Case Dismissed

Jeff Wolf really helped me out and you are really good at what you do thank you for all your hard work.

— Adrian D.

Outstanding, professional and easy to work with

I had the privilege of working with Colleen and Jeff at Wolf Law, and they exceeded every expectation I had. From the very first conversation, both attorneys were incredibly responsive, clear, and genuinely invested in my situation. They explained everything in plain English, kept me updated at every step, and fought hard to get the best possible outcome for me.

Their professionalism, attention to detail, and calm guidance through what could have been a very stressful process made all the difference. I truly felt like I had a dedicated team on my side, not just another law firm.

I would and will recommend Wolf Law without hesitation to anyone in need of trusted, skilled legal representation in Colorado. Thank you both!
