Testimonials

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!

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.

Outstanding Results

Mr. Wolf was great to work with. He explained all the aspects of my case in great detail and his communication is excellent. My case was for DUI and Jeff was able to get my sentence deferred which from my understanding, is a very rare outcome.

Gets the job done!

I recently hired Mr. Wolf for a 23-year-old case and I am extremely satisfied with his service. Mr. Wolf was very knowledgeable, professional, and compassionate throughout the entire process. He kept me informed every step of the way and made sure I understood everything. The outcome of my case was better than I expected, as it was dismissed. I would highly recommend this firm to anyone in need of a criminal defense attorney. Mr. Wolf is efficient and effective, and he truly cares about his clients.

Wow

Unfortunately, I have required an attorney more than a few times. That said, Jeff is the most intelligent, competent, compassionate, committed, aggressive representation to be found, without a doubt. Facing a felony DUI, no proof of insurance, careless driving and cruelty to animals (my dog gets more love than most people in the world), followed by two DURs (driving under revocation), I pretty much felt I was screwed. After hiring and firing two attorneys, I called Jeff. Note: Do your research before you waste money, and do whatever it takes to get the money for proper representation. I met with Jeff based on his peer reviews, client reviews, education and experience; all of them positive and 100 percent accurate. Twenty minutes into the consultation, all my built-up stress and anxiety had been significantly reduced. I thought my driving privileges were over for a while. Jeff showed me what I needed to do to get a restricted license, which I was able to do within a few days. Following that he made two DURs, jail time offenses, turn into one zero-point traffic violation. Then, one year to the date of my run-in with the law, Jeff and I went to trial. The no insurance charge was dropped. I was insured. The cruelty to animals charge was dropped after the first day of trial. On the second day, I was found not guilty of DUI, DWAI and careless driving. The time, effort and determination Jeff put in was clear, and his strategies and trial skills were clearly superb. No better counsel can be found in my opinion.

Excellent Representation!

Jeff was with me from Day 1 after getting pulled over for an accused DUI charge. Jeff’s knowledge of the process and responsiveness to my questions, concerns were impressive. His professionalism to me and in court was excellent. Jeff truly made this stressful and emotionally taxing situation 100 times better. I am grateful he was referred to me. I would definitely recommend Jeff if ever faced with a driving-related charge. Jeff will be my first call in the future for any legal counsel (which hopefully, is never again).

— Scott

Incredible Representation

I cant say enough positive things about my experience with Jeff Wolf. This was my first time needing a lawyer for representation, and Jeff made me feel informed and secure throughout the whole process. I couldn’t have asked for a better person on my side. He was able to navigate me thru a stressful time and it meant the world to me. He was great with DA; calm, but firm and determined to get me the best possible result. Also, the presiding judge clearly thought highly of Jeff Wolf. I would highly recommend Jeff Wolf to anyone looking for legal representation.

I Recommend Jeff Wolf to Anyone Needing Legal Defense

I retained the services of Jeff Wolf after I received a DUI. During the free consultation, Jeff reviewed his services and the details of what would happen before, during and after my trial. He was very thorough, supportive and diligent in ensuring all my questions were answered. I am thrilled with the level of service he provided for an extremely reasonable fee. Jeff was accessible and reassuring throughout this entire process. The end-result of my hearing was exactly what I had expected based on Jeff’s counseling. This is a direct result of his knowledge and experience with the court and the system. I was very impressed with his closing presentation in court and his professionalism and felt that the judge reduced my fines and my sentence because of Jeff’s efforts. I have already recommended him to two other people and will continue to recommend him to anyone requiring the services of a defense attorney.

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!

100% Worth It
