Case Dismissed

I met with a probation violation complaint for a DUI in Summit County. I live outside of Colorado, in Boston. I felt hopeless. I felt like my only option was to travel out to Colorado, give myself up and just see what happened. That would have meant jail and thus loss of job and loss of house.

I called Jeff and talked to him about my case. His experience in this area put me at ease. Jeff guided me through everything I needed to do to see this case through. The greatest thing is that I never had to leave home to clear this up. At the end of the day Jeff cleared my case (Case Dismissed) without me ever leaving Boston. Jeff is incredible, and his team is equally amazing.

I can’t thank Wolf Law enough for what they have done for me. I have a new outlook on life thanks to Jeff.

Best in the business

Working with Mr. Wolf was an absolute privilege. Having never been in trouble with the law before, Jeff was there for me each step of the way from the day before I turned myself in, to the very end of my case, which he was able to help me get dismissed.

A true professional, he was nothing but honest and fair to me. He showed me and my family the utmost respect through a difficult time. At a point when I felt alone, Jeff was there to make sure I would be ok.

He is true to his word, and each step of the way, he and his team will keep you informed on any and all items that need to be addressed.

Because of Mr. Wolf, I can continue with my life and move forward. Thank you, Jeff Wolf, and everyone at the firm. If anyone I know ever needs a defense attorney, I will recommend the best in Colorado. Wolf Law.

Wolf Review

I hired Jeff Wolf to represent me in a DUI case where I was charged, but was not the one that was driving the vehicle. From the very beginning I felt that I was in good hands because he made me secure in the fact I was innocent and that, though I was drunk, I did not do anything against the law. Every time I emailed him, I received a response immediately. I felt that he knew the system well, and how to handle this “game” of law. When he had to deal with a health emergency, he made me aware of my options and what he thought would be my best choice, which was being represented for court by another attorney that knew my case inside and out. He just called me this past Monday to let me know my case was dismissed! I would recommend Jeff Wolf to anyone being charged with anything in Colorado. He knows the laws of Colorado and will keep it real with the possible outcomes of your case.

Cassandra Monahan

Cassandra has represented me several times. She has always been professional and effective. The outcomes were better than expected and communications and empathy were top-notch. I would highly recommend!

— Aaron Olson

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.

— Kyler A Witt

Jeff Wolf Cares About You as a Person

Jeff Wolf is extremely timely, reliable, and efficient. He cares about you as more than just another case, he cares about you as a person. Jeff worked with me on my out-of-state case and went above and beyond to ensure that I received the best possible outcome.

— Anonymous

Out of 5 stars I give Wolf Law 21,000

I had Cassandra Monahan defend me on an absolutely ridiculous Felony Menacing charge.
Cassandra fought for my life and got me a deferred judgement and only 12mo probation. After probation all charges against me were thrown out and all records sealed.

She was straight forward and diligent with my case. I can’t recommend Wolf Law and Cassandra enough.
