Client Testimonials

Mr. Sheehan not only considered the legal merits of my case but also took my personal situation into account. He executed a legal strategy that ensured the best possible outcome for me at trial but also ensured minimum disruption to my career and family as well.

Attorneys are oftentimes reluctant to give candid recommendations and opinions. Michael and I were able to establish a relationship in which we mutually analyzed my options and communicated transparently about my case.

While thoughtful and professional, Michael is an aggressive defense attorney. He skillfully balances a positive and professional demeanor with vigorous negotiations and legal arguments.

I always felt that Michael was MY advocate, not just facilitating a process.

I’m fortunate that Mike Sheehan handled my case from beginning to sentencing and would recommend him without hesitation. Criminal charges I faced were over-the-top exaggerated, thanks to an embittered ex-wife. Mike was able to neutralize and bring reason to the process and final outcome, ultimately reached through a plea bargain. However, he was prepared and more than willing to go to trial. Area District Attorneys know that about him. Unlike many defense attorneys, Mike does not look to just cut a deal and move on to his next case. His very professional interaction with me and, importantly, with my family, was face-to-face, inclusive, respectful, and compassionate. He even made his paralegal’s services available to help my family navigate the challenging justice system. Mike is experienced in the entire Denver area and works the whole criminal defense spectrum from minor to murder charges.
