To echo what others have said, he is very easy to work with and talk to. I never felt uninformed and he was excellent with communications.

Michael Sheehan is a phenomenal attorney. He exemplifies the highest level of integrity, professionalism, subject matter knowledge, and legal skills.I came to meet him when a family friend and young professional needed the best attorney possible. She had been put in the most precarious of circumstances by her workplace supervisors. They had undermined her and her efforts to meet all of their unrealistic expectations and requirements. Ultimately, when she self-reported an omission in a report (made under duress), they egregiously accused her of forgery.Thankfully, Michael took her case and negotiated on her behalf, completely changing the outcome of her case. Thanks to him, his dedication, legal knowledge and skills, this young person's sense of hope has been restored. And just as important, thanks to him, the trajectory of her life and career will not be permanently impacted.Michael genuinely cares about his clients. He sees their humanity and treats them with the utmost respect, providing guidance throughout the entire legal process. In so doing, he models the attitude and regard other participants in the legal system should accord his clients.Lastly, he diligently and ethically accounts for the time he spends on his cases. He actually reimburses unearned retainer funds, as opposed to some lawyers who prefer to engage in needless or pointless busywork to justify not only keeping as much as they can but ramping up costs.Again, Michael Sheehan is a phenomenal attorney and, overall, a phenomenal human being. If you want/need the best legal representation from a seasoned, skilled, and knowledgeable attorney--who embodies dignity and integrity--Michael Sheehan is the absolute best.
It has been almost a year since my case. During this time, my mental state was severely damaged and I couldn't sleep well all night. I always feel that this is not Michael's level and there may be multiple language barriers. I mistakenly thought that signing the agreement was half the battle. What I didn't expect was that I would need to attend a 9-month domestic violence treatment course. Tuition is equivalent to hiring another defense attorney. My defense attorney, Michael, was supposed to tell the prosecutor and the judge about me at trial. (Non-citizen, unable to work legally) If I couldn't pay the tuition, I wouldn't have finished the case. I don't know the point of having a non-violent person take this course. Put couples who were already on the right track into trouble again.
My relative had an unfortunate and serious allegation against him. The DA was being unreasonable even though the evidence was weak. Michael took the case to a jury trial and won the case. He was communicative, comforting and confident throughout the process. I hope I never need a defense attorney again but I would definitely use Michael and would highly recommend him for any criminal proceeding.
Mike is a top notch attorney. We couldn't have asked for better communication and service. We slept better knowing that he was on my son's side. You are in excellent hands with Mr. Sheehan!
I can’t thank Michael enough for helping me through such a difficult time and for his exceptional legal expertise. In addition to winning our case, Mr. Sheehan explained everything so I understood all of our options and he was so kind. His profound knowledge of the law, attention to detail, and commitment to my case led to the judge overturning a very unfavorable plea deal. Before we hired Michael, I was frustrated and overwhelmed by the process. It was a blessing to have someone on my side who was so compassionate and dedicated. I highly recommend Michael to anyone seeking exceptional legal representation.
I had such a great experience. When I got into my motorcycle accident and was not able to do much on my own, Mr. Sheehan helped me out with everything. Constantly staying up to date with me and giving me advice on my next steps to take while getting all the information to make sure I got everything I was owed. He is always willing to help and go the extra mile to make sure you're taken care of. Definitely would give him a higher review if I could. Highly recommend to everyone.
We had a difficult legal situation that needed an expert and after our first consultation with Micheal, we knew he was the right lawyer for us. We found Micheal to be caring, professional, incredibly experienced, knowledgeable and a clear & straight forward communicator. He also has all the right relationships and contacts that allowed him to provide the appropriate resources and recommendations for our specific situation. In the end, Micheal was able to help us achieve the outcome we desired and we couldn’t be happier with the services he provided!
If you find yourself in the unfortunate situation of needing a lawyer in this sue happy world, I highly recommend Micheal Sheehan to represent you! Very Professional, understanding, knowledgeable, and just all around a good guy.
Michael did exactly what he said he would do and that’s more than I can ask in todays society. Top notch work Michael and you will have many referrals in the future.Thanks
I would like to say thank you so much to Michael and his hard work, I had 1 felony and 2 misdemeanor cases and was looking at years in prison. Michael made me feel comfortable and I didn’t hesitate to hire him, all three of my cases were resolved and I am pleased with the outcomes of my cases and im in control of my future. Michael will work hard for you and won’t ignore any of your questions he’s detailed and knowledgeable in his field 👍🏽 Thank you Michael for your hard work.
I thought Michael’s legal counsel was below par. Michael gave minimum effort and was slow to respond to multiple emails. In hindsight, hiring Michael was the worst decision and I will forever regret hiring Michael’s legal firm.
Response from the owner: Jeff - I am sorry you are unhappy with the way your wife’s case was resolved. I was surprised to read your review, as it was my understanding that the matter resolved satisfactorily on August 28, and I hadn’t received any negative feedback from her. I immediately followed up with your wife after I saw your review. She has options, and if you, or your wife, would like to discuss those options further, please give me a call. Your satisfaction, and the satisfaction of all my clients, is always my top priority.
Michael is a great attorney! My husband and I couldn’t be happier with the way our case was handled. He is a very honest lawyer! Thank you Mike!!
I had the distinct pleasure of having Michael Sheehan guide me with my case in Arapahoe County. He was extremely professional, thorough, compassionate, and communicated effectively. I would highly recommend him to anyone in need of his services.
Michael was retained as my Attorney for an unfortunate legal situation I found myself in. Being unfamiliar with the system and legal process, Michael set me at ease and helped by explaining in detail each process we went through. He was able to get a fair and reasonable outcome for my case. He is an active listener and puts the needs of his client at the forefront. I would not hesistate to highly recommend him.
Mr. Sheehan is excellent! He took up my case with very short notice and immediately delivered with top notch skill and expertise.
Unbelievable professionalism, courtesy, intelligence and knowledge. My case was not complex but could have gotten out of hand very quickly. I was having lost sleep and anxiety that I didn't know anyone could ever have. Michael went above and beyond to ensure my life did not spiral out of control. His knowledge and experience with the workings of the law are exemplary. I can't thank you enough for resolving my case.

Michael recently helped me out with a difficult legal situation. Before our initial consultation I was extremely anxious. Michael did a great job of explaining the law and what I could expect.

I highly recommend Michael to anyone facing a criminal matter.

Michael handled my case professionally, he communicated well, and the result he obtained was in my best interest. I highly recommend him as a defense attorney.
Michael walked us through a lot complex issues, offered us options, shared what was a likely outcome, advised on positive actions to be taking now, and aggressively worked with the DA on our behalf. Likely total costs were shared up front as well. Highly recommended.
I wanted to take a moment and share our experience using Michael Sheehan for a court case for my son. It was for a very serious traffic ticket with a lot on the line. I had no prior experience using an attorney so I was a little nervous in the process of finding and choosing someone. I knew Michael was an amazing fit from the very first conversation and he was super knowledgeable and very easy to talk to. On the day of court he was great with my son, very forthcoming and professional and communicative. We were pleased with the outcome and very glad we hired Michael.
Michael was very attentive, informative and helped things move along quickly in a dark time and he prices his services unreasonably low. I'm not sure how he does what he does and stays afloat.
Intelligent and caring individual
Michael is hands down the best he was referred to me by a bondsman and was the best decision I’ve had had a very intense case and he honestly made me worry about it less as I knew he was doing everything he could to make sure I got the best outcome always made sure I was okay with what he was recommending and always explaining everything in good detail to help me understand he will always be my go to and will be recommending him to friends and family if they have problems

We hired Michael after a misunderstanding. Michael was very understanding, compassionate and knowledgeable. He communicated with us regularly and answered any and all questions we had promptly.
