Our Approach

DUI defense built around the person, not the file number.

G&S DUI Attorneys at Law is a criminal defense firm focused on representing individuals charged with driving under the influence and related offenses. Michael R. Gruszeczki and Dustin E. Smith are former prosecutors who have handled DUI cases from both sides of the courtroom.

That experience helps the firm evaluate how a case was investigated, how the evidence may be challenged, what the prosecution must prove, and how the criminal case may affect a client’s driving privileges.

Some cases may involve an unlawful traffic stop or improperly administered field sobriety tests. Others may involve breath testing, blood testing, medical issues, video evidence, witness credibility, or police procedures that may significantly impact the prosecution’s case.

Why Former Prosecutors Matter

Experience viewing a DUI case from both sides of the courtroom.

Evaluate the State’s theory

Former prosecution experience provides perspective on how police reports, chemical testing, witnesses, and charging decisions may be presented against a defendant.

Identify litigation issues

A careful defense review can uncover issues involving the traffic stop, arrest, field sobriety testing, breath or blood evidence, video, medical conditions, and police procedure.

Prepare beyond the first court date

Good preparation considers negotiation and motions, but it also keeps the case ready for a bench trial or jury trial when litigation is necessary.

How We Work

A deliberate process from the arrest through the final resolution.

1

Review the arrest

Start with the citation, police reports, testing, video, witnesses, and the timeline of events.

2

Separate the two tracks

Identify both the criminal charge and any driver’s-license consequences or administrative deadlines.

3

Analyze the evidence

Compare the State’s theory with the objective evidence, testing records, medical facts, and applicable procedure.

4

Identify defense issues

Evaluate suppression issues, evidentiary weaknesses, credibility questions, and other defenses supported by the record.

5

Prepare the strategy

Plan for negotiation, motions, hearings, and trial while keeping the client informed about the available choices.

6

Stay accessible

Questions do not stop between court dates. Communication remains part of the representation throughout the case.
