Details
Attorney Brian Douglas Sloan has devoted his entire career to DUI Defense Representation.
Mr. Sloan has spent the last 20+ years SOLELY focused on DUI Defense Representation, having represented 4,600+ DUI clients, and defended approximately 100 Felony and Misdemeanor DUI Trials.
Mr. Sloan has received a perfect 10-out-of-10 on Avvo.com; a 4.9-out-of-5.0 on Martindale-Hubbell; received the 2013 - 2017 Southwest Rising Star award from Super Lawyers, before aging out of the category; and was honored with the Featured Attorney of the Month Cover Story in Attorney at Law Magazine. Mr. Sloan earned both the Top 100 Trial Lawyers Award and the Top 40 Under 40 Award from National Trial Lawyers; as well as the Top 40 Under 40 Award from American Society of Legal Advocates. Mr. Sloan was ranked a Top Lawyer by North Valley Magazine; a Superior DUI Attorney by National Advocacy for DUI Defense; and one of Arizona's Finest DUI Lawyers by Arizona's Finest Lawyers. Mr. Sloan also received a "Superior" ranking from The National Advocacy for DUI Defense, LLC, is "Lead Counsel Rated" by Lead Counsel.org; and received the "10 Best Client Satisfaction Award" by the American Institute of DUI/DWI Attorneys." Mr. Sloan has also been acknowledged as a "Lawyer of Distinction," which is awarded to less than 10% of attorneys in each state.
In 2015, Mr. Sloan was named an "Attorney to Watch" in a featured issue of Attorney at Law Magazine, and has been requested to be a guest author as one of the Top 10 DUI Lawyers in the Nation in an Amazon.com Best Selling book called A Cup Of Coffee With 10 Of The Top DUI Attorneys In The United States. In 2015, and 2017 - present, Mr. Sloan was also named one of the Top One Percent in the Nation by the National Association of Distinguished Counsel.
Mr. Sloan was awarded the "Best Business" by ThreeBest, was named a "Lawyer of Distinction" by Lawyers of Distinction, and was acknowledged as a "Top 10 DUI Defense Attorney" by Attorney and Practice Magazine.
In 2019, 2020, 2021, 2022, 2023, and 2024, Mr. Sloan was named one of less than a dozen SuperLawyers in DUI Defense amongst all attorneys in Arizona and New Mexico. In 2022, Mr. Sloan was the only DUI Defense Lawyer in the United States featured as a 'Power Lawyer' in USA Today.
However, he prides himself on being the 'Best Value in the State' when it comes to DUI Defense Representation, due to his years of experience, sole focus on DUI Defense, and what he charges for his representation. He has created a type of contract that he calls Bifurcated Representation, which results in his clients paying reasonable flat fee payments, only for the services that they need, and not for the services that they don't. Mr. Sloan doesn't charge his clients for busy work, and proudly use the motto, "Hire Any Other Lawyer, and You Will Pay A Lot More Money and/or Get A Lot Less Experience."
Mr. Sloan is a Founding Member of The Arizona DUI Team; has previously been a guest speaker at multiple statewide seminars; and has created a Guide to DUI Representation used by lawyers throughout the state.
