Why LLF for DUI

Defense built on government experience

Most DUI lawyers have seen these cases from exactly one chair. Charles has worked all three sides of the courtroom triangle:

  • Government investigator — six years. More than 700 civil & criminal investigations for the Denver Department of Human Services (City & County of Denver): surveillance, evidence handling, chain of custody, detailed reports, and sworn testimony in civil, criminal & administrative proceedings. He knows how the state's file was built — because building files was his job.
  • Prosecutor — eighteen months. Deputy District Attorney in Colorado's 12th Judicial District: first-chair charging decisions, plea negotiations, and trials across six counties. He knows what makes a prosecutor reduce, dismiss, or dig in — because he made those calls himself.
  • Defense counsel — twenty-plus years. Colorado private practice spanning criminal defense and family law, now focused on Longmont, Boulder County & Northern Colorado's Front Range — the same evidence instincts, turned on the state's case.

Every DUI file at LLF gets read three ways — as the investigator who built it, the prosecutor who would charge it, and the defender who has to beat it. Weak stops, broken chains of custody, and overreaching counts rarely survive all three readings.

That's the firm's premise in one sentence: the state's experience, working for you.
