Best Criminal Atty out there
I have previously hired Steven Barnes to represent me on a couple different cases when I was much younger. He knows the law and got me to best outcome for my case. I still reach out to him to get recommendations for other attorneys in other areas. I trust Mr. Barnes judgement and recommendations. If you need a criminal atty, look no further!

Steve was phenomenal!
Steve was so helpful and understanding with my domestic violence case. He was able to get the charge dismissed! He is a great person and reasonably priced. I would recommend Steve to anyone!

Professional and Knowledgable
I had been falsely arrested for domestic violence. I contacted Steve and after consulation hired him to defend my case. I refused to accept a plea deal and we took it to trial. The jury deliberated for approximately 12 minutes, and I was found not guilty and was acquitted of charges. I was very happy with how Steve handled the case. He was very professional in the court room and was very good at preparing me for trial. I am glad that I was able to find Steve and that I had hired him.

The Best!!
In the worst time of my life being falsely accused I didn't know what to do the first thing my mother did was call Steve not knowing what to do it was nearly midnight and he answered! So amazing! As soon as we met him he made us feel so much better about everything. He never promised anything but gave advice and listened and was able to help get what could have been a class 4 felony dismissed. He worked hard on my case and with the comforts of him and his wife Patty I couldn't imagine how scared I would have been but having these wonderful people to help made me feel wonderful and at ease. I would advise if you need help to go here he works with you on the payments and never makes you feel bad. I'm so thankful for him and his team!

Pleasantly surprised
Steve Barnes was wonderful to work with. When I first entered the office I felt comfortable right away. Mr. Barnes was easy to talk with and never rushed me. He listened to all my concerns and answered all my questions and made me feel like I was in good hands. I hired him on the spot and from then on his service was unquestionably the best that I have ever experienced. He truly cares about his clients and you feel it. He is very knowledgeable about the Law and is up front with what all you should expect with your charges and the court proceedings. At one point I was scared and confused and he had me come in to talk and go over things again; just to ease my mind. When you hire his firm you not only get Mr. Barnes but you get the other two lawyers in his firm and his paralegal's help as well. Everyone was great to work with and I was pleasantly surprised with how well they are respected at Arapahoe County Court and how they were able to get me better results with my case then I could ever have hoped for!

I have a commercial driver license and drive semi truck for a living. This winter, I had a moving violation in Denver, CO. I could pay the fine, but it will go to my driving record and stay there for 3 years - this could increase my insurance payment. I hired Mr Steven Barnes and my case was quickly resolved. Moving violation turned to non moving violation, no points, no record and I didn't have to come to court. Job well done! Thank you Sir!

Worth every penny
Steve Barnes was an excellent lawyer. I contacted Steve because I received a 3rd DUI. He was extremely knowledgeable and walked me through the entire process. He fought hard to get me the best possible outcome. He was worth every penny. His vast experience paid off for me in court as I received a better sentence than expected. I was always able to reach him for any questions I had. I would highly recommend him for anyone who needs representation.

Superb Attorney
Mr. Barnes is an amazing attorney. He treats his clients like family and fights for them as if they were too. He is very knowledgeable and engaged. If I were to ever need legal assistance again in the future I would have no reservations in hiring Mr. Barnes to represent me.

The best lawyer
Mr. Barnes handled my case in Denver District Court, We went to jury trial and I was found not guilty Mr. Barnes believed in me and did a fantastic job.

Great Representation
My son was facing potentially serious alcohol and drug charges. Through Steve's work and relationships with the DA's office, he was able to help reduce the charges that resulted in a fine with no probation.

Adams County Case
My son was facing a class 4 felony with 4-16 years in prison and 3 misdemeanors. Steven Barnes worked with the DA's to get the felony dropped and the charge was 1 misdemeanor with supervised probation for 1 year with an alcohol evaluation. Thankful

Knowledgeable and Caring
Mr. Barnes was not only very knowledgeable of the law, but he was genuinely interested in the facts and truth of my case. It is frightening to know how easily an allegation of criminal wrongdoing can be made, and that is especially true regarding allegations of a sexual nature. Mr. Barnes listened to the facts of my case with an objective mind and upon accepting my case, he kept me informed every step of the way during my 2+ year legal nightmare. Mr.Barnes was truly compassionate and worked tirelessly to prove my innocense. He never pressured me to accept plea bargains even though it would have made his life easier and avoided the toll it would surely take on me and my family. When I had questions, Mr. Barnes never made me feel like a bother and he always responded to my calls in a timely manner. Mr.Barnes is a man of integrity and I have no doubt that he represented me wholeheartedly. He believed in my innocense, he fully realized the gravity of the allegations against me and that he held my life in his hands. I hope to God I never need an attorney ever again, but if I did, I would have no reservations in hiring Mr. Barnes to represent me. With all sincerity, thank you very much...
