6-Month Jail Sentence Reduced to 90 Days

I was arrested in May 2014 for a warrant that I had since 2010 for DUR, I was facing a six month jail sentence that would have caused me to lose my business, home, as well as once again re-offend me. After countless calls and conversations and meetings with numerous attorneys I was referred to Jeffery Wolf. By simply speaking with him over the phone I felt a little at ease, until I met with him and after that I was completely at ease. He made feel the way an attorney is suppose to make a client feel. He was extremely personable, caring, honest, completely honest, and very detailed as to what his process is and what will take place in court.

On the day of my hearing Jeff arrived a little early and had me wait in the hallway while he stepped into the court room and went to bat for me. The result was a 0 point violation allowing me to keep my DL, a six-month jail sentence reduced to 90 days in-home detention, and a $67 fine, which was way more than I expected.

I highly recommend Jeff he is an excellent attorney that takes your case as serious as you do. I hope I never have to hire an attorney again but if I do without a doubt Jeffrey Wolf will be my first and only thought.

The best lawyer you could ever hire !!!

Jeffrey Wolf is the best lawyer you could ever hire. He most definitely went way above and beyond the call of duty for me and my case. I’m sure that some of you have hired other lawyers in the past and it seemed like they drug their heels, and wouldn’t return calls, which made you feel that they didn’t care about you.

As far as I’m concerned that will never happen to you if you hire Jeffrey Wolf. He treated me like I was either his best friend or a member of his family, that’s how I felt dealing with him. I honestly looked forward to his calls. He seems like a super cool/good guy. If I lived in Colorado I would be honored to even hang out sometime, maybe shoot some pool, go bowling, ect just have fun. But the most important thing as far as business goes he got an amazing result for me in the case he represented me for. If yall don’t hire Jeffrey as your attorney then you’re making a HUGE mistake that you will probably regret the rest of your life. Again tyvvvvvvvm Jeffrey Wolf for taking care of me. You are the best.

I Would Give Wolf Law 50 stars Out of 10 if I Could

I wanted to take a moment and give a MASSIVE THANK YOU to Wolf Law (and Colleen Kelley specifically)!

I had contacted Wolf Law recently regarding a previous offense and legal registration questions. This was for Sex Offender De-registration for the State of Colorado. After taking the time to review my case, my information, etc. etc, Wolf Law was able to take my case.

Considering the amount of time and effort involved to be removed, I am extremely grateful for Colleen Kelly/Wolf Law’s assistance in the matter.

After almost a decade, I was removed from the registry, and can now put a long chapter of my life behind me.

I would give Wolf Law 50 stars out of 10 if I could.

Again, THANK YOU Wolf Law for all your assistance and help in this matter!

I would very very very much recommend Wolf Law for your legal needs and/or situations. Please take a moment to contact them if you need to!

Professional. Attentive. Experienced. Successful.

I was referred to Jeff by one of my friends who was recently represented by Wolf Law in his DUI case; I will be forever grateful for that recommendation. Jeff made this extremely stressful process feel much more manageable from start to finish. He was always responsive and highly communicative, even throughout my barrage of anxiety driven questioning. He was a maestro in the courtroom and was able to get me the absolute minimum penalties. He even got certain areas of my very unique case dismissed – saving me thousands of dollars in the process. While I hope I never have to, I will surely be recommending Wolf Law as DUI representation to any of my friends and family in the future.

Incredible Defense with the Perfect Outcome

When I was arrested at a concert hall for trespassing and placed in a detox center it didn’t feel right. I had confronted the police in order to find out why they where arresting somebody I knew and within seconds of my questioning I was in cuffs and associated with a crime that I seemingly had nothing to do with.

When I was released from detox I thought it was over but then I understood that I had to appear in court and my previously clean record was facing the documentation of a criminal charge. I wanted to try to keep my record clean and with some help I hired Wolf Law.

Given the relative simplicity of my case I only had to meet at the office of Jeffrey Wolf a handful of times. From the first visit I could tell that Jeffery was very professional and very serious. As more of my case was revealed and in consecutive meetings I could tell that Jeffery was building a strong defense.

While he couldn’t promise me any certain outcome his resolve to defend me as strongly as he possibly could was obvious. On my first court date, before much of the details of my case where known, I was accompanied by Jeffrey Wolf’s associate lawyer Colleen Kelley. Colleen defended me with a skillful amount of experience and made it possible for Wolf Law and me to buy more time and obtain the legal information required to build a defense.

On my second court date, after having met several times, I was accompanied by Jeffrey. Jeffrey told me to wait outside the courtroom and I complied. After roughly 20 minutes he reappeared to me with a welcoming smile and gave me the good news that he had gotten my cased dropped.

I’m not quite sure what he did in those 20 minutes but I can say with satisfaction that it was an amazing job. I felt, with fingers crossed, that it was a possibility that my case would be dropped but when it actually happened I almost couldn’t believe it. I’m very thankful for the work and service that was provided by Wolf Law. For them I have the utmost respect and my recommendation to anyone needing legal service goes to them with 100% certainty in their ability to promise and do their best.

The Best!

Jeff is very professional, knowledgeable, and as good of a lawyer as there is. I had a restraining order full of false allegations, and Jeff got everything dismissed. Even though it was a restraining order, Jeff treated my case as important as any other case. Thanks, Jeff!

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.

Fully and Enthusiastically Recommended

When I was arrested for DUI/careless driving, I was overcome with a profound sense of hopelessness – I couldn’t eat, I couldn’t sleep, and I thought my life (including my career) was ruined. Making the decision to call Mr. Wolf for a consultation was the best decision I could have made. His immediate response set my mind at ease and gave me a the peace of mind that I so desperately needed.

Upon meeting him in person, I was thoroughly impressed by his experience and expertise, but what really struck me was his personable demeanor and genuine interest in helping me. He was very patient in explaining the legal process and made sure I was well prepared for every step of the way.

There is no doubt that his representation and advocacy, as well as the advice he had given me in order to prepare for court, resulted in an outcome that was more positive than I had dared hoped for (a DWAI with license intact and a reduced probation sentence), allowing me to move forward with my life. Mr. Wolf far exceeded my expectations, and I would absolutely recommend him to anyone seeking legal counsel.

Helped Me Through a Rough Time!

I became quite the habitual traffic offender with two speeding tickets and one ticket with two charges totaling 12 points. Jeff brought the 12-pointer down to a 3-pointer and a small fine, and saved my license with the two other tickets at bay. I had a lot of trauma at the time of the tickets, and he not once judged me. He is quick to respond to a call or email or text and walks you through each process. I am so glad I listened to earlier reviews because he made this process so much easier. I would definitely recommend him to anyone dealing with similar infractions and problems!

Colleen Kelley and Wolf Law

In the past few years I have had the unfortunate circumstance of needing a criminal defense attorney. I cannot overstate how fortunate I was to have chosen Colleen Kelley. I can honestly say that without Colleen on my side that I would have been sentenced to significantly more time and more serious charges than were warranted in my situation.

Colleen is undoubtedly a major reason as to why I am free today and able to move on with rebuilding my life. I would without hesitation recommend Colleen to anyone who needs a criminal defense attorney.
