Hire this man.

Got my case dismissed! Helpful and transparent through the whole process. 100% would hire him again if I needed.

We Beat The Odds

William recently defended me for TWO DUI's against me. These two cases had been pending since 2022, and as everyone knows- Arizona is the harshest state in the US to receive a DUI in, so the odds of me beating these cases or having them reduced were very slim. William graciously took my case, was ver...y communicative, and straightforward with me at all times about everything the case was going through at the time. We strategized a plan, stuck with it, and before I knew it, the judge had agreed to drop ALL DUI charges for a plea of reckless driving instead. William, I want to say THANK YOU for everything you did for me. You not only saved me from harsher charges, but also my career, my reputation, and helped give me peace of mind and a new start. HIRE THIS MAN IF YOU ARE FACING DUI CHARGES, he is who you want!

Great Lawyer!!!

I hired Mr. Parven to represent me in a case involving an overweight and a criminal offense while driving a commercial truck. From the moment he took my call, he was very professional and knowledgeable, and gave me a free consultation of what he thought the result of the case was going to be. Every...thing resulted exactly like he said. The case was dismissed and i saved a lot of money in tickets. He always kept me up to date with the status of the case and followed up with me frequently to ensure that everything was on track. If you need a lawyer for Criminal Defense, Traffic Ticketing, or DUI, i strongly recommend Mr Parven.

The Best Decision I Made...

I do not have a lot of experience when dealing with attorneys but I am extremely glad I chose Mr. Parven to represent me. When someone is in the situation where they need to hire a defense attorney for the first time it can be overwhelming and very scary. William was approachable, down to earth, and ...sympathetic to my unique circumstances. He was honest and upfront about my situation during our initial meeting. He was flexible and worked with my financial situation. He broke down step by step what would be occurring in my case and what he would be doing to help me. He also encouraged me to be proactive and help myself by completing certain tasks that would be viewed favorable by the courts at a later date. William took a personal interest in me and my situation as it became increasingly more complex thanks to my own stupidity. Even though I actually caused more problems than I should have, William seemed to always be there to help me out of a jam. I owe this man a lot and in my humble opinion is the best attorney I could have chosen. William fought for me. Yes I made some mistakes that landed me in hot water but there were some very unfortunate circumstances that surrounded these events and a lot of people started to kick me while I was down. William was the one person who stood up for me and prevented me from losing everything. I hope I never need his services again but I will recommend him to anyone who wants an honest, hard working man who will fight for what is right.

Dedicated attorney, gives re-assurance, and Won.

Facing a charge that would have ended my employment and therefore my livelihood, I was fortunate to find William Parven. While I know attorneys can never give guarantees, Mr. Parven answered my many phone calls, often after hours to give me assurance while we went through our 7 month court battle. ...He was able to provide enough support to me, and evidence questioning the charges, that in the end, the charges were able to be dismissed. Mr. Parven was not just a great attorney challenging every aspect of the case against a very dedicated prosecutor, he was a re-assuring hand during the drawn-out proceedings. I highly recommend him to anyone seeking a defense attorney. May I never have a situation where I need an attorney again, but if William is in practice, I will seek his help. Thanks Sir!
