Great Attorney, The Best !!

I had an old case from another state for dui, 20 years ago to be exact , that had came back to haunt me where the State of Texas was not renewing my CDL which i need for my career due to the info from another state. After much research i decided on Doug Murphy's law firm and have been very happy with... my results from him and his staff.While he got me cleared with the Texas DPS on the old information they had on me , he also gave me a contact info on a friend of his in the other state so i could get the old info from 20 something years ago took care of, thus saving my CDL and career. Hands down the best !!!

Best lawyer ever!

Doug immediately made me feel at ease as soon as I spoke to him. He and his team handled my case perfectly and I got the best outcome ever, all charges dropped and all property returned. He and his team are truly the best and I have already recommended them to a friend who needed help.

Phenomenal!

Just 2 weeks before my 27th birthday I was a passenger involved in a horrific motor vehicular accident. Unfortunately enough I was arrested for FSRA involving bodily injury & DWI. After doing some online research I was able to discover the Doug Murphy Law firm & knew right then that’s who I wanted ...to represent me in both of my cases. With their great knowledge & expertise in cases like mine they were able to identify me as a passenger & got both of my cases dismissed in just a matter of months; considering one was a felony & the other a misdemeanor that is. Highly recommend for anyone seeking legal counsel as they are an excellent team. Thank you so much to the Doug Murphy Law Firm!

DUI and DWI lawyer | May 13

Relationship: Fellow lawyer in community

"Doug Murphy is one smart lawyer! His natural courtroom talent is a pleasure to watch and I don’t know many other lawyers as dedicated to their clients as Doug. Many years ago I was defending a particularly difficult DWI in Houston. Doug happened to walk in, watch about 5 minutes, and at a break gave me a hint about cross examining this particular police officer. Doug knew his history and shared it with me. It was very helpful and my client enjoyed an acquittal based largely on that cross examination. In sum, Doug is talented, trustworthy, and is willing to teach others. I highly endorse him!"

"I had the pleasure of working with Doug Murphy for 8 plus years. I had the luxury of learning from his 15 plus years of fighting for his clients. Doug will work harder than any other lawyer, all the while, knowing more law than most other lawyers combined. He has a wealth of knowledge, experience, and expertise in all aspects of DWI law. Not only does he tirelessly fight for his clients, he volunteers his time helping other lawyers. Whether it is a lawyer in the courthouse with a question or traveling across the country to teach other lawyers, Doug is always gracious with his time and knowledge. Doug Murphy is a lawyer's lawyer. His family and friends, clients, and fellow lawyers are fortunate to have him; I certainly was to work with him and still am to call him my friend."

"Attorney Murphy is a very skilled and artful litigator of the highest order. His ability to advocate effectively for his position is remarkable. His reputation for achieving great results for the citizen accused by the government of a crime is well known. His reputation for excellence in all matters is a hard earned national one. This reputation far exceeds the bounds of his state as evidenced by this lawyer from Central Pennsylvania not only knowing of him but in that I can personally attest through first hand observation his high level of proficiency in litigation and in the defense of the citizen accused. Superior, fantastic and skilled. He is the one I would put in my corner every time."
