DWI Dismissed!

Thankyou Michael Mercer! First offense DWI charge case dismissed! Super helpful and very knowledgeable in his field. I would definitely recommend him to anyone in need of an attorney.

I hired Mercer and Keirnan because of their experience handling DWIs and other charges. Working closely with them throughout my case, it became very clear that I had made the right decision. They will always have a permanent place in my cell phone just in case anyone I know is in trouble and needs a... good defense attorney. Hire Michael Mercer and Casey Keirnan.

Michael Mercer was a fantastic attorney

Michael Mercer helped me tremendously with my DWI case in Harris County. It is a brutal experience to go through, but with Michael's help and expertise, I was able to get a lot of positive information about the court system and able to get the best case scenario considering the possible outcome had ...I not been represented. His office and presence was very professional. The courts in Harris County can be tricky and nuerotic, but he held his own with respect to the client and laws that govern. I recall one instance where another lawyer in a flamboyant suit approached the Assistant D.A., and was immediately scorned. Michael Mercer on the other hand, approached the same Assistant D.A. with a calm demeanor and young, respectful attitude and was able to get a successful appeal and eve conversation going. I recommend his services, as he is still helping me out professionally/legally even after my case has been closed. Thanks,

"Michael Mercer is a beast in the courtroom. I recommend Michael for both misdemeanors and serious felonies alike, as he gives all of his cases his utmost attention. His drive and tenacity make him an excellent criminal defense lawyer. Nobody can say that a prosecutor has outworked Michael on a case. It is no wonder that he always obtains excellent results for his clients."

"I am pleased to endorse attorney Mike Mercer. I watched him grow up to become a fine young man and achieve his dream of becoming a trial lawyer. He is truly a rising star who no doubt will distinguish himself as an outstanding advocate in the course of his career. He cares about his clients and is relentless in the courtroom. He practices with and is mentored by one the best lawyers I have have ever seen in the courtroom--John "Casey" Keirnen. You would do well to consider Mike if you need help with a criminal law matter."
