Testimonials

The best in Colorado!

Mr. Jeff Wolf was a pleasure to work with. He did an excellent job representing my case. He walked me through the whole process answered all of my questions and concerns. I am very pleased as his client with his professionalism, attention to detail, communication, and most importantly the result he was able to achieve for my DUI case to be dropped. Definitely will be recommending Jeff Wolf Law to family and friends.

Mr. Wolf Blew My Expectations Out of the Water

After recently facing two relatively serious traffic violations, Mr. Wolf was able to obtain an outcome for my case that far exceeded my expectations. From the initial consultation onward, Jeff was extremely professional, punctual, and confident. Jeff clearly defined our objectives and provided me with some serious peace of mind. I wouldn’t hesitate to recommend Mr. Wolf’s services to any family member or friend in need and couldn’t be more pleased with his representation!

— Michael

Hit and Run Charges

I had multiple charges stacked against me by the CSP office for a questionable “hit and run” in my office parking lot. Jeff reviewed the video evidence and was able to get the charges reduced from 26 points against my driver’s license down to 4. He was also able to get the fines reduced to the minimum amount! Jeff was extremely knowledgeable and helped ease my fears each time we spoke and explained the whole process and what to expect along the way. Thank you, Jeff!

APPRECIATION

I would like to place on record the immense appreciation for Ms Colleen Kelly, Partner at Wolf Law LCC. I had an opportunity as a Solicitor to interact with her on behalf of one of my clients in a DV Matter. Her professionalism and knowledge of law is absolutely outstanding. She is extremely honest and straightforward in her legal advice. She always keeps the interest of the client a priority and safe guards the interest of the client at all times. She is an asset to the legal team and adds value with her expertise and knowledge.

— Nirvikar Singh, Advocate Supreme Court of India

Clear, honest & delivered

From the beginning Cassandra was honest and gave me confidence and clarity about possible and likely outcomes. She worked closely with prosecution to get me the best outcome available and succeeded in doing so. For a straightforward, honest, and hardworking firm that advocates on your behalf I recommend Wolf Law.

Professional, Passionate and Knowledgeable

This was my first experience with the law, and Jeffrey Wolf did a fantastic job of guiding me and my family through this. He was always available to answer any concerns I had, realistic in terms of what we were looking at, and passionate about getting us through this. He truly took my case to heart and was a lifesaver through a trying time. Thanks to him, I still have a chance to succeed in my career and lead a normal life!

A Great Help in a Time of Turbulence

After being convicted of a DUI for marijuana, I quickly searched for an attorney. I chose to contact Wolf Law first because of the certifications and positive reviews that I saw. I am very glad that I made this choice. This was my first time in trouble with the law, so I didn’t quite know how to handle the situation, but with just a few meetings, phone calls, and emails I felt confident towards the resolution of my issues. Jeff explained everything thoroughly and made sure I knew everything I needed to know and more. I personally needed only a few meetings and talks, but I know that Jeff would be glad to meet or talk as much as necessary. He is clearly very passionate about his work and is a well of legal knowledge. I began with several charges and seeing an overwhelmingly bad outcome in my future, but as Jeff and Wolf Law fought for me, the charges faded away until only one remained and even it was reduced. I left with what I view as the best possible outcome for my given situation. Wolf Law not only helped mitigate the consequences of my mistake, but also granted me great comfort and guidance through the whole experience.

Great results. Great to work with.

I had an amazing experience working with Wolf Law, and specifically Cassandra Monahan. I was involved in a car accident and Miss Monahan not only got the ticket dismissed, but did it quickly and effectively. Moreover, she was great to work with, showing a genuine care for me and my case. I would highly recommend Wolf Law and Cassandra for anyone who needs representation with respect and results!

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.

— Shelly O'Hayre

Outstanding Results

I have contracted Cassandra twice now and both times had outstanding results. In the first case she got the results I tried to obtain with ease. When I spoke on my own behalf to the district attorney they wouldn’t budge in any way. Once Cassandra was involved it was like watching a master at work. She stated the facts and provided evidence to back her argument in my situation and actually got better results then I initially wanted. Then in a second unexpected turn of events she yet again worked her magic. She remained real with me the entire time and explained the reality of the situation and prepared me for the worst while still working hard to achieve the best results and let me tell you she far beyond exceeded expectations. Her hard work and perseverance caused unheard of result and I couldn’t be more satisfied. Throughout the entire process she never misled me, always remained patient and understanding; she always listened and always made sure to go the extra mile to make sure things went as planned. I was never charged with surprise fees or felt taken advantage of financially in any way. What I paid for the service and commitment to my case is unheard of in this day and age. I would recommend Cassandra and Wolf Law to anyone I know who is having legal troubles. You will not be disappointed! Sincerely thank you again to Cassandra and Wolf Law for everything you have done.
