Working with Mr. Wolf

I cannot speak high enough of Mr. Jeffrey Wolf! He was very pleasant to work with and explained each step of the journey from start to the final video teleconference with the judge. He negotiated a much lower sentence with the DA from DUI to DWAI. He reiterated several points that were then considered by the judge and taken into account in deciding my sentence. He was always prompt in any communications and worked tirelessly on my case to get a very favorable outcome for me. I would whole-heartedly recommend Mr. Wolf as you can be ensured it felt like I was an individual that truly mattered to him and his practice. From the very first phone call, I had nothing but respect for him and felt I was in good hands, that he then proved! You can’t go wrong with Mr. Jeffrey Wolf!

Expedient, Thorough and Effective

Fortunately, I don’t find myself needing legal representation often…only once before have I needed an attorney. My situation was interesting…I was given a disorderly conduct summons and felt it was far beyond the pale in terms of its validity. I didn’t want this on my record and needed help navigating the legal process. I did some research on a few attorneys and read about Jeff Wolf’s practice. I called Jeff and we spoke the same day. He listened to me and I met with him a few days later. He took the time to explain his process and approach, which made sense to me and seemed to be in the right dollar range for what we were dealing with. Thankfully, my case was dismissed. Jeff took the time to show the DA that there were inconsistencies all over the place and that there was no way I was guilty…likely shouldn’t have even been issued a summons. As I said to Jeff, I hope I never have to talk with him again, but I won’t hesitate to call if need be.

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.

Would Have Been Lost Without Wolf Law

I was charged with my first DUI and was referred to Jeff by a friend of mine. He gave me a realistic expectation of what would happen and is an expert at navigating the process. Jeff is always incredibly quick to respond and is very knowledgeable. He is professional and represented me well in the courtroom. The experience of being charged with a DUI is a terrible, humiliating and challenging event – having an experienced attorney was priceless!

Colleen is one of the best!! Goes Above and Beyond

I had to use legal services regarding a personal matter and I contacted 3 other lawyers. Colleen was the only one who took time to understand the issue but only explain legally how it can be addressed.

Also, I was surprised when she got me the desired result but she kept moving forward to make sure I had material for a potential criminal case. It shows that she cares and understands legal strategies.

Jeff Helped Me Feel Safe Again

I would highly recommend attorney Jeffrey Wolf. He consistently demonstrates knowledge and professionalism, both in and out of the courtroom. His expertise helped me to understand the legal process. As a victim of domestic violence, I looked to Mr. Wolf to assist me in obtaining a restraining order. His compassion combined with skill helped me to feel safe again.  I reached a positive outcome in my case and felt informed, confident, and cared for with Mr. Wolf in my corner.

Case commitment

Thank you! Cassandra helped me through every step of the way. She was extremely flexible and answered anything i could ask. She was the biggest and nicest help I could ask for, on top of being resourceful she got my case done earlier than the state said. I would highly recommend Cassandra to any one she was amazing.
