Phoenix DUI Lawyer Representation

At The Law Office of Brian Douglas Sloan, we understand how devastating an arrest for DUI can be. A Felony or Misdemeanor DUI / Drunk Driving conviction can result in loss of reputation or job; costly fines and fees; required attendance at substance treatment / education classes; suspension or revocation of your driver’s license; increase in, or cancellation of, your auto insurance; placing an ignition interlock device in your car; and, in all cases, jail or prison time.

In Maricopa County, where most commuters travel the freeways, and public transportation is generally lacking, losing the privilege to drive can be devastating to a person’s career, as well as one’s personal life. The Law Office of Brian Douglas Sloan has extensive experience within in the criminal justice system and knows that good people can sometimes make a mistake or be falsely accused of a crime.

We remain on the cutting edge of DUI / Drunk Driving defense by keeping up with the current law, latest case rulings, scientific literature, legal treatises, and scholarly articles written in the area of DUI / Drunk Driving defense, and have established credentials through rigorous continuing legal education. Our clients rely on our quality trial skills and aggressive representation.

If you have been arrested for DUI / Drunk Driving, be sure to hire a Phoenix DUI attorney who is successful and experienced in defending DUI / Drunk Driving cases. Some attorneys only dabble in DUI / Drunk Driving law, and are not equipped to handle the complicated legal and scientific nature of most DUI / Drunk Driving cases. An experienced DUI / Drunk Driving defense attorney can identify police mistakes, unreliable breath, blood, and urine tests, and other legal issues that often make the difference between successful and unsuccessful results in DUI / Drunk Driving cases.

“I am one of only a handful of Phoenix DUI Lawyers that focuses solely on DUI Defense representation.”

I have spent my entire career focused on DUI Defense representation, having defended more than 4,100+ DUI clients in the past 18+ years.

If you’re looking for a divorce attorney, tax attorney, or civil attorney, then I can comfortably say: “I’m not the one for you”.

Coming up with traditional, as well as outside-the-box motions and defenses for my clients, often with good results, is the hallmark of my practice.

Lawyers that say they are “aggressive”, or “will fight for you”, are a dime a dozen. They use these phrases because that is what they think people want to hear. The truth of the matter is, being “aggressive” rarely gets the client anywhere in these court systems. Being “aggressive” isn’t the same as being good.

The same is true for the lawyers that claim to do DUI Defense… and Criminal Cases…, and Accident cases…, and Divorces. A Jack-of-all-Trades is a master of none. By handling all different sorts of cases, they take away from their ability to truly focus on DUIs, and keep up to date on the latest changes in DUI Defense Representation.

What I offer is intelligent, quality DUI defense, at an exceptional price.

I am one of only a handful of Phoenix DUI Lawyers that focuses solely on DUI Defense representation.

I have not only taught other lawyers how to do DUI Defense Representation at statewide seminars, but I produce DUI Legal Guides used by defense lawyers across Arizona.
