Testimonials

The BEST person to have at your side

When I sat in my car that day, fear twisting into nausea, frantically scrolling through an endless sea of lawyer ads. I had no idea who to trust. I chose Jeff. He looked like an angry guard dog—and in that moment, I needed that.

Over the next three years, I learned he was far more than that. He never gave false hope; anything he told me, he could defend. I paid him once—one upfront fee—and he stayed with me the entire three years. He called with updates, stayed on top of every detail, and fought for me at every turn.

I can’t say your case will be like mine, but the fear and terror I lived with for three years were dramatically reduced by having Jeff in my corner. I’d never been in a legal situation before. He guided me with expertise, calmness, and total honesty. Looking back on that version of me frantic, in my car, hiring Jeff Wolf was one of the best decisions I’ve ever made.

And that angry guard dog look? It hides a genuinely warm and caring person.

Professional & Effective

I worked with Cassandra P. Monahan (Associate Attorney) on more than one legal matter. Her communications were clear and non-judgmental. Transparency in progress and outcomes was above expectations. I am delighted with Cassandra’s and the firms service, created trust throughout the process.

Grateful for the professionalism and effective execution.

— Michael Perkins

Beyond the Best

Jeffrey Wolf has been a beacon of hope to me when my situation seemed limited and unlikely of a positive outcome. He represented me for a DUI and as a domestic violence victim and did a phenomenal job on both. Not only was he able to defend and represent me, but his empathetic and ethical demeanor offered hope to myself and someone I truly care about. My partner and I are eternally grateful for his service, and I hereby recommend him without hesitation since I could not imagine a better result without him representing me.

— Marisabel

Great Law Firm

Jeff Wolf and Cassandra Monahan were wonderful to work with. Very professional and thorough.

— Laura A.

Great Attorney

I contacted Mr. Wolf through a reference from a separate out-of-county attorney’s office. I was very pleased with his professional attitude and staff, but mostly the results he was able to achieve for my case. I would definitely recommend Jeff and hire him again if I ever need to.

— Jeremy

I Had a Great Outcome in My Case

Jeff Wolf was recommended to me by a colleague I have known since my youth. Accordingly, I met with Jeff. I also met with other attorneys in the Denver area in preparation for my legal issues. I decided to choose Jeff because I had a good feeling about him from the moment I met him and because his ethics and views regarding the vision for his legal practice were aligned with what I hoped for despite having no experience in the legal system previously.

This decision turned out to be one of the the best I have made in my life…literally. I cannot adequately express here how much Jeff’s hard work, determination, knowledge, professionalism, experience, and clear understanding of what I am certain he has a passion for (helping others beyond just being an attorney and defending clients in court) has meant for me. I think he has exceptional skills. I had a great outcome in my case due to the defense Jeff provided in court.

More importantly however, Jeff helped me manage the emotional and professional stress I felt. Jeff reassured me when I most needed reassurance, and ultimately, transform a situation I initially felt was a life changing event into a learning experience that I was able to navigate successfully through his precise and comprehensive guidance. I would recommend Jeff to any member of my family and certainly to anyone to whom his services would apply.

Out of State? No Problem!

I was from out of state and ran into some trouble, when I realized for the first time in my life I needed an attorney. I called around and did my research, and I am so happy I chose Wolf Law and most importantly I received Cassandra Monahan as my attorney. I can’t speak high enough praise of Ms. Monahan. My family and I are very close and me being over 26 hours away was extremely hard for us, and understanding laws from another state were even harder! She provided us with in depth information on the laws and was there every step of the way and truly fought for my case. She followed through on everything we asked and went above and beyond. I am so thankful to have found Wolf Law and cannot recommended Ms. Monahan enough!

— Lesley B.

Exceptional Representation

I could not be happier related to the representation I received from Cassandra and her team. Outstanding expectation calibration, more important is her command and understanding of recent precedent setting case law…without that dexterity my case does not get dismissed. Cassandra is available, prepared and has healthy disdain for nonsense from prosecutors and/or judges. If you are in need of tenacious representation – I would highly recommend Cassandra!

— David Reynolds

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.

Jeffrey Wolf is an Exceptional Defense Attorney

From my very first conversation, I knew that I was in good hands being represented by Jeffrey Wolf. He was extremely honest about my situation and gave me clarity about possible and likely outcomes, never sugarcoating anything. Mr. Wolf has excellent communication skills as he explained all the aspects of my case to me in great detail. He skillfully navigated me through the most difficult and stressful event of my entire life while always exhibiting concern for my personal wellbeing throughout the process.

I couldn’t have asked for a better attorney to represent me. Mr. Wolf was great during negotiations with the DA, great in the court room (which was always done via WebEx), always very calm and confident, but firm and never let himself get pushed around by anyone. As a result, Mr. Wolf negotiated a much lower sentence with the DA which allowed me to avoid prison time enabling me to be home with my wife and continue watching out for my 91 years old father.
Thank you, Mr. Wolf!
