Practice areas

Tom Dean has been using his law practice to advocate for nationwide cannabis policy reform for over 20 years. After honing his courtroom litigation skills for several years in Ohio and Arizona, Tom accepted the position of Legal Director for the National Organization for the Reform of Marijuana Laws (NORML) and relocated to the organization’s headquarters in Washington, DC. As NORML’s Legal Director, Tom initiated and managed many matters of national importance to cannabis policy reform. He also coordinated the efforts of the NORML Legal Committee and NORML Amicus Committee in key cases throughout the U.S. He continues to serve as a lifetime member of the NORML Legal Committee, Chairman of the NORML Amicus Committee, and Legal Director of NORML’s Arizona state chapter. In 2016 NORML honored his 20 years of achievements by inducting Tom into the organization’s Distinguished Counsel’s Circle. Tom is also active in other important cannabis organizations on both a local and National level. Of note, he is a founding member of both the National Cannabis Bar Association (NCBA) and the Arizona Cannabis Bar Association (ACBA), organizations that seek to help other lawyers develop and understanding of the many unique aspects of cannabis business law and other emerging cannabis related areas of practice. In recognition of his work in cannabis law in Arizona, in 2016 Tom received the President’s Commendation award from the Arizona Attorneys for Criminal Justice (AACJ). Outside of the courtroom, Tom enjoys presenting at legal and business seminars and conferences around the country.

As a person with prior felonies and previous weed strikes, I knew I had to hire an attorney when I got charged with possession of marijuana and drug paraphernalia. I called Tom Dean’s office and spoke with a woman named Pam, who by the way, is very informative, outgoing and genuine. After I spoke with Pam, I felt comfortable about moving forward with a consultation with Tom Dean. From the minute I spoke to him I knew this was the attorney that I was hiring. Tom is very knowledgeable when it comes to marijuana cases and weed laws. He answered all the questions I had, and explained everything thoroughly. Tom fought and negotiated with the prosecutor to get me unsupervised probation. At the time of sentencing, the judge was going for one year unsupervised probation. Tom made sure the judge knew my medical card had lapsed and how it was indeed a technicality. The judge understood and gave me ten months unsupervised probation for a misdemeanor marijuana thanks to Tom. I’m so grateful to have hired Tom Dean. I was worried because of my prior convictions but he was in my corner every step of the way and he was willing to fight for me in trial if I chose to. Tom is a persuasive attorney and handled my case very professionally. I highly recommended him for anyone facing marijuana charges. Thanks Tom, your a life saver.

Life saver & kept me sane
We had a consult with him and he spent over 2 hours the first day and said anytime we had any addition questions or concerns we could call him. He always communicated with us and is up to date on all marijuana laws. He is a knowledgeable attorney with experience and compassion for patients. I truly can't say enough about his ethics.

Having Tom Dean represent me was one of the best decisions I have ever made as I was facing serious charges. My consultation via phone felt more like old friends conversing. Very easy to talk to and very reassuring, I immediately knew I was in good hands, (and I can be very skeptical). Not only is he professional, knowledgeable and has a strong work ethic, but his compassion and sincere concern for me and my well-being was evident in his work. He offered me the support and advice that I needed during some very trying times in my life. If you need an experienced lawyer who will tell you exactly how it is with (no BS) and guide you through your difficult time I highly recommend Tom Dean. (Facing: extradition. prison time)

Excellent attorney for any criminal defense case
I was cited for a very minor accident which resulted in a 2nd citation for a hit and run. Unfortunately, as I learned if you don't know the laws for this, even the most well meaning person can get caught up in this type of situation. Attorney Dean was there for me every step of the way. Despite my reservations that we would be able to get the prosecutor to understand the circumstances and the fact I wasn't guilty due to some complexities, Mr. Dean handled it with ease and grace. He succinctly explained to the prosecutor that the case was not clear cut and the charge would likely not hold up in court. Despite my reservations Mr. Dean took the lead and handled all of the discussions with the prosecutor thus alleviating my nerves in having to defend myself alone. He was able to get the charge dismissed and I'm forever grateful. I definitely wouldn't have had the same results if I had to go it alone, it would have impacted my life in a very negative way if I hadn't had his help. Thank you Tom, you are a wonderful person and a fantastic attorney.

Tom Dean Saved my Life!!!
Simply put: Tom Dean is the best marijuana lawyer in Arizona. I was facing serious prison time for selling marijuana to another patient. I was just hoping to avoid prison. My previous lawyer told me that I would have to plead guilty to a felony and spend 90 days in the county jail. I was going to lose my job and had two kids. My friend referred me to Tom Dean and about three months later, my entire case was dismissed. It was like a miracle. My wife actually cried when we got the news. If you have a marijuana related case, do yourself a favor, talk to Tom Dean. You will not be disappointed.

"Tom is one of the best lawyers I know. He is one of the few I would have represent me. Nobody knows more about marijuana law, and nobody is more aggressive. He thinks outside of the box and really cares about his clients. You would be lucky to have him represent you!"
