Great Attorney
Bill is amazing he helped guide me through my problem even before it was time to acquire his services. Once it was time, he hit the ground running. He makes sure I understand everything going on and gives me my options. He has never led me to do anything that wouldn't benefit me and has fought tooth and nail for me. I would recommend Bill to anyone who wants honesty, fairness, and straightforwardness.

Honest hard working law firm
Donnie McClellan represented me in a criminal case in which I was wrongfully accused of assault. Donnie fought hard to win my freedom back with class and style. He is nothing but professional and hard working, and I wouldn’t hesitate to call him again if needed. Donnie and Bill McAdams put mine and my family’s worries to rest, all at a fair and affordable price. Before finding the McAdams Law Firm I went with a lawyer from Denver that ended up getting disbarred half way through my case, doing nothing for me and charging me almost 10k! A real life nightmare situation. Thank goodness Donnie was there to help me through it. Thank you so much.

Best at what they do!
McAdams Law has done an exceptional job with my case. Their knowledge and experience in law is second to none. He's very honest and fair when it comes to what he can do for you. Bill, and his team, are very professional and work incredibly hard to make sure you get the best result possible. His prices are very fair. His office is a very comfortable environment and easy to find. I don't regret giving my business to McAdams Law!

Fantastic Lawyer
I cannot say enough good things about McAdams Law Firm! From the initial consultation and all the way through the process, they were prompt and helpful, and made me feel at ease in a very stressful and seemingly hopeless situation. They were able to reduce my traffic misdemeanor to an infraction and lower my points enough for me to keep my license. A total lifesaver! If you are looking for kind and very capable lawyers, I would highly recommend them. They are fantastic!

Great Attorney
Bill McAdams is an excellent attorney who knows his way around a courtroom. The DA twisted and turned things around, but Bill threw it right back at them making them look like fools. He skillfully brought the truth to light and I’m grateful for all his help.

Thankful for Bill
My family and I are very thankful for Bill McAdams and his associate attorney, Donny. Due to a false accusation made by my husband’s ex-wife in a play for custody of our boys last year, we were thrown into the legal system and a long, drawn-out process to get out. We were very fortunate to have Bill McAdams on our side as he skillfully guided us through the legal process and in the end masterfully represented my husband in court. If you want to see as a master at his work, go watch a court case being handled by Bill. He is a great orator and his expertise and experience really shines.

Stellar work and Professionalism
I would like to thank Mr. McAdams, Mr. McClellan, and staff for all their hard work. They were very well suited to take my DUI case and defend me on the case. Both attorneys were present and available throughout the whole process to help and answer any questions I had. After explaining my case and evaluating the evidence Mr. McAdams and Mr. McClellan were able to get my DUI charge dismissed, which was what I was hoping for. I would highly recommend this law firm for DUI defense.

Excellent representation!!
The McAdams Law firm is as good as it can gets in Weld County. Feeling overwhelmed when needing representation for DUI case, I consulted with Bill and his staff and was relieved to find a lawyer who I trusted. Bill and his staff treated me with genuine respect. All aspects and options of my case were explained by Bill at the consultation and throughout the process. Excellent communication skills with me and in the courtroom. I highly recommend the McAdams Law office.

My Experience with McAdams Law
It's a lot of fun to share humorous attorney stories,...until you need one. Gets serious pretty quick. From the initial meeting through the end of my case Mr. McAdams treated me and my concerns with respect and strict professionalism. I felt like I was a member of a team that had a strategy and plan of execution. I was always well informed, knew what expectations to have and provided options. The knowledge of law, inside out, and the attention to detail make a lot of difference! Thank you for your excellent representation!

Help when you need it.
Bill and his paralegal Suzanne are very professional. I have used Bill 3 times since 2008. Have always been impressed by how he handles himself in front of the prosecuter and judge. He explains himself well and is there to talk if you need him. When appointments are made he doesn't make you feel rushed and really listens. I appreciate how the office works together to make the process go smoothly. Realizes that everyone makes mistakes and they don't judge you. He takes you life, your family and what you maybe going through very seriously.

Bill is awesome!
Bill was amazing! He helped me beat my case! Took a plea bargain for permitting a minor to operate a motor vehicle in the state of Co. w/out a valid drivers license... The original charge I received was driving under revocation of a DWAI... I was lookin at a year in jail! Thank you Bill!!!

Amazing Lawyer
I met with Bill regarding a DUI charge I was facing. Right off the bat I could tell that he was incredibly well versed in the field. He laid out the facts of my case and explained very thoroughly what I could expect. He was always available when I had questions and went above and beyond on getting a traffic ticket I had received while my case was ongoing reduced, with no extra charge. I am glad that I hired him because I feel that the whole process would not have gone as smoothly otherwise. It was definitely money well spent, and I will be keeping his card in the event I need legal counsel in the future.

A trustworthy professional Attorney
I was charged with DUI and looking for answers to serious questions surrounding my arrest and charge. I reached out to several defense attorneys in my area to conduct short interviews and address the facts of my case. When I met with Mr. McAdams or Bill I found him extremely knowledgeable. Everything that Bill said became facts during the legal process. Mr. McAdams while drawing from his considerable experience as a prosecutor and a defense attorney was able to pinpoint the outcomes in my case before they happened. He did this without over promising and he did not under deliver on what he believed he could accomplish in my case. My charges were eventually dismissed and I could not be happier with Mr. McAdams approach to my case. If you are facing criminal charges it is imperative you receive sound legal advice and representation. I highly recommend Bill McAdams he will address your questions and concerns and most importantly he will make the best possible decisions in your case.

Hire Someone Else
The McAdams law office is unprofessional and unresponsive. I hired Bill for a legal matter and he failed to follow through with what we discussed during my initial consolation. Bill was slow to obtain evidence and did not present it as soon as he received it resulting in an unfavorable outcome. He is slow to respond to phone calls and mentioned that I am only but one of his many clients and that he did not have time to take my calls. During one of our rare conversations he even ill advised me of the law. If you want the best possible outcome for your legal matters hire someone else.
