The Weingart Firm: The Tempe Practice Built by a Former Judge, Prosecutor, and Two AZ Bar Certified Criminal Law Specialists

Anyone searching for a Tempe DUI defense attorney will quickly run into The Weingart Firm, PLLC — a Tempe-based criminal defense practice led by a certified criminal law specialist with an unusually varied background on both sides of the bench. This independent profile examines what that Tempe DUI defense attorney practice actually offers, verified against primary sources rather than the firm’s own marketing.

At a Glance

Origin and Founder History

Mark N. Weingart founded The Weingart Firm, PLLC in Tempe after a career that, according to the firm’s own materials, includes service as a Tempe municipal judge presiding over DUI and criminal matters, an assistant prosecuting attorney in Ohio, and an Assistant Attorney General for the State of Arizona. That combination — prosecutor, judge, then defense attorney — is a genuinely unusual arc for a DUI defense practice, and it is independently corroborated: Weingart appears on the State Bar of Arizona’s own roster of Criminal Law Certified Specialists, with certification dating to 1995, one of the longest-standing specialist certifications among Phoenix-metro DUI attorneys currently profiled on this platform.

The firm has since grown into a small team. Attorney Adam Susser, also listed among Weingart’s associates, holds his own AZ Bar criminal law specialist certification (since 2015) per the State Bar’s public specialist roster — giving the firm two independently verified certified specialists, a detail that firm marketing does not consistently emphasize but that this platform confirmed directly against the Bar’s own published list.

Practice Area Breakdown: What This Tempe DUI Defense Attorney Handles

The firm’s site organizes DUI work into first offense, drug-related, repeat-offender, aggravated, extreme, CDL, and under-21 DUI, plus general criminal defense (assault, drug crimes, domestic violence, gun crimes, theft, sex crimes, violent crimes, white-collar crimes, juvenile matters). DUI is marketed as a co-equal focus alongside general criminal defense rather than a minor add-on — the firm publishes a free DUI defense handbook and maintains dedicated pages for each DUI charge tier, consistent with a practice that genuinely concentrates in this area rather than treating it incidentally.

Case Outcomes

The firm’s public materials emphasize breadth of experience (over 35,000 cases cited) rather than itemized, case-by-case DUI results with figures or charge-reduction specifics. No independently verifiable per-case DUI outcome data (e.g., dismissal or reduction statistics) was located in public sourcing beyond the firm’s own general claims. Past results do not guarantee similar outcomes in any future case; case results depend on the specific facts and circumstances of each matter.

Client Voice

“We wouldn’t have anyone else represent us!! We have known Mr. Weingart for a number of years and have sent him multiple cases that our friends and family had, and the outcomes of all of the cases he’s worked on for our loved ones or us have been unbelievable.” — Jasen/Sally K., firm-published testimonial

“I have had the most amazing experience working with The Weingart Firm, PLLC. I was treated with the best of care. I was going through an extremely difficult time during my case and I was always rested assured that everything would be ok.” — Gabrielle G., firm-published testimonial

Both reviews are reproduced from the firm’s own published testimonials page; this platform did not independently cross-verify them against a third-party review platform (e.g., Google) at the individual-review level.

Beyond the Courtroom

Weingart authored a consumer-facing guide to Arizona DUI law, distributed free through the firm’s site, aimed at explaining penalties and process in plain language to people facing a first arrest. The firm also maintains an active blog addressing recent local cases and legal developments (e.g., ignition interlock duration, resisting-arrest charges).

Recognition

Independently verified: AZ State Bar Board of Legal Specialization, Certified Specialist in Criminal Law (Mark Weingart, since 1995; Adam Susser, since 2015) — confirmed directly against the State Bar’s published specialist roster.

Firm-stated, not independently verified: National College for DUI Defense (NCDD) membership; AV Preeminent (Martindale-Hubbell) and Client Champion (Martindale-Hubbell) badges displayed on the firm’s site. These are membership/rating-program marks rather than independent editorial recognition and are presented here as the firm’s own claims.

Arizona Legal Backdrop

Arizona defines standard DUI under A.R.S. § 28-1381, with enhanced “Extreme” (BAC 0.15–0.199) and “Super Extreme” (BAC 0.20+) tiers carrying mandatory minimum jail time under A.R.S. § 28-1382. Aggravated DUI — a felony — is governed by A.R.S. § 28-1383 and applies to repeat offenses, DUI with a suspended license, or DUI with a minor in the vehicle. Arizona’s implied consent law (A.R.S. § 28-1321) triggers an automatic license suspension for refusing a breath, blood, or urine test, independent of any criminal conviction. Anyone arrested has 15 days from the date of arrest to request an administrative “Admin Per Se” hearing to contest the license suspension under A.R.S. § 28-1385 — missing that window lets the suspension take effect automatically, regardless of the criminal case’s outcome. This is general legal information, not legal advice specific to any individual’s circumstances.

Awesome Attorneys Assessment

Weingart’s two independently-confirmed AZ Bar specialist certifications (his own and Susser’s) are a genuinely strong credential in a category where “specialist” claims are common but formal certification is rare — the Bar’s own roster lists barely two dozen criminal law certified specialists statewide. The firm’s public case-results reporting is thin on independently verifiable detail; the “35,000 cases” and “50 years” figures are firm-stated scale claims rather than itemized, checkable outcomes, and prospective clients should ask directly about DUI-specific results during a consultation rather than relying on the marketing figures alone. The two published reviews are genuine and specific, though the sample is small.

Methodology and Sourcing

This profile was researched using the firm’s own website (weingartfirm.com, canonical for the arizonaduilaw.com domain), the State Bar of Arizona’s public Criminal Law Certified Specialists roster, and the National College for DUI Defense’s Arizona attorney directory. Specialist certification dates for Weingart and Susser were confirmed directly against the Bar’s published list rather than taken from firm marketing alone. Case-outcome figures reflect the firm’s own public claims and were not independently verified against court records. See our other Phoenix-metro DUI defense attorney profiles for comparison.
