Inside the Phoenix practice of an attorney who, by his own account, has spent more than two decades declining any case that isn’t a DUI — and built a flat-fee billing structure around that single-practice focus.

Origin: A Single-Practice Bet
Brian Sloan earned his J.D. and a Certificate in Dispute Resolution from Pepperdine University School of Law before relocating to Phoenix, where he has spent what his own materials describe as 18 to 21-plus years (the figure varies by source and publication date) focused solely on DUI defense representation — declining, by his own account, virtually any criminal matter that isn’t a DUI or a charge filed alongside one. He is a founding member of an organization called The Arizona DUI Team. That single-practice focus is the clearest structural differentiator in this batch: where most firms here handle DUI as one line among several criminal-defense services, Sloan’s practice is built to do nothing else.
Practice Areas
Per the firm’s own Avvo profile, DUI and DWI representation makes up 95% of the practice, with the remaining 5% limited to offenses charged directly alongside a DUI. The firm reports having represented more than 4,100–4,600 DUI clients (the figure has grown across different published dates) and having taken roughly 100 felony and misdemeanor DUI cases to trial.
Case Outcomes
Awesome Attorneys was not able to locate an itemized, case-by-case results log with independently verifiable outcomes. The firm’s site references a “Case Accomplishments” page and describes a “Bifurcated Representation” flat-fee billing model designed so clients pay only for the specific services their case requires. One client review describes a difficult Aggravated DUI matter (driving on a suspended license with prior offenses) that cost the reviewer a 25-year government career; the review speaks to the hardship of the situation and the attorney’s support through it but does not state the case’s final legal disposition, so Awesome Attorneys is not treating it as a documented result.
Past-Results Disclaimer: Aggregate client counts and trial totals are the firm’s own claims, not an independently verified case log. No past result guarantees a similar outcome in any future matter.
Client Voice
The firm holds a perfect 10-out-of-10 aggregate on Avvo (347 combined Avvo/Lawyers.com reviews) and a 4.9-out-of-5.0 on Martindale-Hubbell, both driven by high review volume. Individual reviews consistently describe Sloan as thorough, communicative, and personally involved through the full process, including handling court appearances directly. Awesome Attorneys did not identify a pattern of unresolved negative reviews across the sources checked at the time of this profile’s compilation.
Community
Awesome Attorneys did not identify documented pro bono programs, board positions, or public-policy involvement for this attorney comparable to some others in this category. This is noted as an absence in what’s publicly available, not as evidence no such involvement exists.
Recognition
Genuine, peer-reviewed credential: Sloan has been named to Super Lawyers’ DUI Defense list for Arizona and New Mexico from 2019–2024, a category the firm describes as including fewer than a dozen attorneys across both states — a real, research-driven peer-selection process. He earlier received Super Lawyers’ “Southwest Rising Star” award for five consecutive years before aging out of that early-career category, which is a distinct, separate designation from the DUI Defense list.
Separate from that: the firm’s marketing cites a long list of additional honors — “Top 100 Trial Lawyer” and “Top 40 Under 40” from the National Trial Lawyers Association, “Top 10 DUI Lawyers in Arizona” from the National Academy of Criminal Defense Attorneys, “Nation’s Top One Percent of Lawyers” from the National Association of Distinguished Counsel, and various “Top Lawyers” placements from North Valley Magazine and Arizona Finest Lawyers, along with a 2022 USA Today “Power Lawyer” feature. Awesome Attorneys was not able to independently verify an editorial, non-membership-based selection process behind most of these; several are consistent with the membership-fee or nomination-based marketing programs common across the legal industry, and USA Today “Power Lawyer” placements have historically run as paid advertising features rather than staff-reported journalism. Readers should weigh the genuine Super Lawyers DUI Defense selection separately from this longer list. The firm’s own marketing also refers to Sloan as a “DUI Specialist” — per this publication’s house style, that word is reserved for Arizona State Bar Board of Legal Specialization credentials, which Sloan does not hold, so this profile does not adopt that language.
The Arizona Legal Backdrop
What follows is general legal information, not legal advice.
Arizona’s core DUI statute, A.R.S. § 28-1381, prohibits driving while impaired to the slightest degree or with a BAC of 0.08% or higher. A.R.S. § 28-1383 covers felony “Aggravated DUI,” which applies to driving under the influence on a suspended, revoked, or restricted license, among other circumstances — the category referenced in the client review above. A.R.S. § 28-1321, Arizona’s implied consent law, means refusing a chemical test after a lawful DUI arrest triggers an automatic license suspension separate from the criminal case itself.
The Awesome Attorneys Assessment
Sloan’s genuine differentiator is focus: a two-decade-plus practice that handles nothing but DUI, a real Super Lawyers DUI Defense selection running six consecutive years, and a transparent flat-fee billing structure. The honest limitation is that this is a solo practice with a marketing profile leaning heavily on membership-based “Top” awards that don’t carry the independent weight of the Super Lawyers selection sitting alongside them — a prospective client should focus on the latter and treat the former as supplementary. This is a strong fit for someone who wants DUI-only focus and predictable flat-fee pricing, not a multi-practice firm for anything beyond a DUI-adjacent charge.
Methodology & Sourcing
This profile was researched in August 2026 from arizdui.com, Super Lawyers, Avvo, Lawyers.com, Elite Lawyer, and the National Association of Distinguished Counsel member directory. Awesome Attorneys did not identify a competing “Brian Sloan” practicing DUI defense elsewhere that could create identity confusion. The Law Offices of Brian D. Sloan did not commission, review, or pay for this profile.
