Why Mountlake Terrace Residents Choose DUIHeroes

Most criminal defense firms handle DUI cases alongside dozens of other practice areas. We don’t. Every attorney at DUIHeroes exclusively practices DUI law. Since 2009, we’ve achieved a reduction or dismissal of charges in an average of 95% of first-offense DUI cases*.

NHTSA Training & Prosecutorial Insight

What sets our approach apart is what our attorneys know about the other side of the case. Every attorney on our team has completed the NHTSA Standardized Field Sobriety Testing (SFST) student course. It is the same certification Washington DUI-arresting officers are required to hold. Jonathan Dichter goes further: he is a Qualified Instructor for the NHTSA/IACP DWI Detection and SFST course, meaning he teaches the course used to train officers who make these arrests. He has also completed NHTSA’s Advanced Roadside Impairment Driver Enforcement (ARIDE) course.

Two members of our team are former prosecutors who know how the state builds its cases. That firsthand knowledge of the prosecution’s playbook shapes every defense strategy we build for Mountlake Terrace clients.

National Leadership & Client Support

Jonathan serves as Washington State Delegate for the National College for DUI Defense (NCDD), sits on multiple NCDD committees, and teaches DUI law as a faculty member of the NCDD. He authored Innovative DUI Trial Tools (7th ed., James Publishing), a national strategy guide used by DUI defense attorneys across the country.

We cap our caseload deliberately. Clients receive one-on-one attention, access to a secure portal for real-time case updates and direct messaging with our team, and interpreter services in most languages.

DUI Charges We Defend in Mountlake Terrace

Washington State treats a standard first-offense DUI as a gross misdemeanor: a serious charge that carries mandatory minimums. Three or more prior DUI offenses within 15 years can elevate a subsequent charge to a felony DUI under state law. 

Our Mountlake Terrace DUI attorneys defend all types of drunk driving charges and related offenses, including:

• First-time DUI charges
• Felony DUI
• Multiple DUI offenses
• Drug-related and marijuana DUI
• DUI involving an accident
• Underage DUI
• CDL and commercial driver DUI
• Out-of-state DUI matters
• Department of Licensing (DOL) administrative hearings
• Post-conviction relief and expungements

We’ve defended thousands of DUI cases across Washington State, including throughout Snohomish County. Both the criminal proceeding and the DOL hearing require prompt action, and we handle both.

How DUI Cases Work in Mountlake Terrace, WA

After an arrest, arraignment typically occurs on the next court day. Entering a not-guilty plea preserves all defense options while the case is evaluated. Pretrial conferences follow, where plea agreements may be offered and defense motions filed. 

An experienced DUI defense attorney can challenge strict release conditions: bail or ignition interlock device requirements, at arraignment, particularly for first-time offenses. Because the DOL administrative hearing runs on a separate track from the criminal case, both processes need attention from the start.

What Happens If You're Convicted of DUI in Washington?

A standard first-offense conviction carries mandatory minimums, such as: 

• Jail time
• Fines
• License suspension of up to two years, depending on the circumstances
• Ignition interlock device requirements
• Completion of an alcohol or drug treatment program

Refusing a breath or blood test under Washington’s implied consent law triggers a separate one-year administrative license suspension, independent of the criminal case outcome.

Beyond the immediate penalties, a conviction creates a permanent criminal record that can affect employment, professional licensing, housing, and SR-22 insurance requirements. The total financial impact (fines, increased insurance premiums, and required programs) can run into the thousands of dollars over several years. The stakes are high, so it's important that you obtain a defense team that knows how to protect you, your rights, and your future.

How We Challenge DUI Evidence

Because our Mountlake Terrace DUI attorneys hold the same NHTSA SFST certification required of Washington arresting officers, they know how to evaluate field sobriety tests against the exact standards used to train those officers. Jonathan’s role as a Qualified NHTSA Instructor means our team identifies deviations in officer technique that many DUI lawyers would miss entirely.

Depending on the circumstances of your case, we may examine:

• The lawfulness of the initial traffic stop
• The accuracy and calibration of breath testing equipment
• The chain of custody for blood samples
• Whether field sobriety tests were administered correctly
• Pretrial motions to suppress unlawfully obtained evidence

Winning a DUI case doesn’t always mean proving innocence. It often means preventing the prosecution from meeting its burden of proof beyond a reasonable doubt. We work with a network of expert witnesses and investigators, and our fully digital case management system gives our attorneys immediate access to your file wherever they are.
