Providing over 21 years of criminal attorney representation

If you, a friend or relative has been charged with a crime, please call me, a Denver Criminal Defense Attorney, immediately to discuss your case. If you needed surgery, you would not want your family doctor to operate on you, you would want a specialist. That is why you should hire me as I specialize in DUI and criminal defense and have been exclusively practicing criminal law for over 20 years. Don’t put your life, liberty, and reputation in the hands of your divorce attorney or the attorney who prepared your will. You need an attorney who is prepared to effectively and aggressively defend you if you have been accused of a DUI, a felony or a misdemeanor.

Call about your specific charges 303-725-0017.
Your first consultation is free.
Financing and payment plans are available

A skilled Denver Defense Attorney can review your case right away

Call now if you think you are a suspect – if you will be questioned regarding a crime – or if you have been arrested. I believe that legal representation at the earliest possible time is the best course of action for you.

I am available for meetings outside of my office. If you are visiting the website on behalf of someone else, please call. We can arrange a visit with the accused at another location.

I am available evenings and weekends by appointment, at my office. Many crime arrests occur outside of regular business hours. We can discuss whether your fees can be financed. Remember, the initial consultation is at no cost.

I am dedicated to protecting your rights and if needed to reduce penalties. My effectiveness is a result of my commitment to my clients. In some cases, the best strategy may be to engage in successful negotiations with prosecutors. In other cases, forceful legal strategy in a courtroom may be the best option. Call now for a discussion of your case and the strategies that may apply to your circumstances. My 21 year legal career has been in the criminal justice system, in trials before judges and juries, and in negotiations with authorities.

Criminal law is a specialty. You may know of a general law firm, and may be trying to decide if they can help you. In my experience, a specialist in criminal proceedings is the best choice. I can knowledgeably go to work on your behalf, protecting your interests and strategizing your defense.

I have built my extensive experience in criminal trials on both sides of the courtroom. For several years I have been defending people charged with crimes. I began my criminal law career as a prosecutor and District Attorney. The perspective that I gained by prosecuting crimes in Arapahoe, Douglas and Jefferson Counties gives me a head start in preparing your defense. I know the kinds of evidence authorities will gather; I understand how they will present it in court; I can develop strategies to counter the case they build and to lessen the consequences you might face.

You may have been represented by a public defender who was appointed to you at the time of your arrest or questioning. This is your Constitutional right, and it was a wise choice to take advantage of that right. Many people discover that these dedicated lawyers are handling a large number of cases and cannot provide the level of legal support they prefer. If you wish to investigate whether it is in your best interest to have legal representation other than a public defender, call now for a free consultation.

  • “Words escape me when describing the job Mr. Martin did for me in a recent criminal case. It was evident from the start that I was not just another client; Mr. Martin made me feel like I was his top priority spanning the entirety of my case. Mr. Martin did not have an easy job spanning the resolution of my case, but his expertise in strategizing coupled with his exceptional quality of work provided for a favorable outcome. Mr. Martin made it a priority to keep me on the same page with the status of my case throughout the whole process. His seasoned experience as an attorney came alive in the courtroom and his perseverance and outstanding knowledge of the law affirmed that I had attained the best legal representation in Colorado. If I had to choose one word to describe Mr. Martin, it would be commitment. Well after I had completed probation, Mr. Martin accompanied me in court to finalize my case at no expense to me. I can confidently assert that Mr. Martin is a paragon of legal representation—bringing forth powerful vigor, a keen intellect, and a sincere passion. If you seek the pinnacle of legal counsel in Colorado, then you need not look any further!”

  • “I don’t know what I would have done without Mr. Martin as my lawyer. I’m usually an upstanding citizen but when I got into trouble, I didn’t know what to do or where to turn. Mr. Martin not only gave me the legal advice I needed but also a great deal of moral support. Whenever I called him, which was quite often, he responded to me immediately with answers and support. He was there for me when I went to court. We had to go back to court two more times, and he was there for me every time. Mr. Martin was able to provide the appropriate documentation and convince the City Attorney to get me a deferred judgment. I was so glad to have him on my side. It was quite an ordeal and I was glad to finally get my life back together. I would highly recommend Mr. Martin to anyone that needs a good defense attorney. You’re the best! Thanks so much for all your help!”

  • “Matt is an awesome attorney. He assisted me with what could have been an uncomfortable situation, and handled it very discretely, professionally, and at the same time, personably. He knows the law and how to navigate the system. I highly recommend him!”

  • “When I was visiting the USA from Canada I got myself into some serious legal issues. I had F4 and F5 felonies pending against me. I had originally hired another lawyer in Denver and they were not even able to have the courts grant me permission to leave the country. Once we hired Matt within 1 week he was able gather the required information about Canada law to present to the judge and was granted permission to leave. Not being from the US and not having a prior criminal history I was not familiar with the process and what to expect. Matt put together a strategy and worked with the DA to eventually get to an outcome that allowed me to return to Canada permanently and unsupervised probation. I am very grateful for the service Matt provided and the outcome he was able to negotiate on my behalf. I owe Matt a big one and so grateful for the outstanding job he did representing me. I would recommended Matt to anyone facing legal issues and would even suggest even if you are from another state, it would be worthwhile to pay the travel expense for his representation. For the professionalism and level of competence in comparison to other lawyers in Denver, Matt made the processes much less stressful and was worth every penny.”
