Colorado Criminal Defense Attorneys
Criminal defense is a civil right — and we defend it in the courtroom every day.
Criminal defense is a civil right.
Most people think of civil rights cases as lawsuits against the police. But the Constitution's protections are tested most often — and matter most — when the government accuses someone of a crime. The Fourth Amendment's limits on searches, the Fifth Amendment's right to remain silent, the Sixth Amendment's guarantees of counsel and a jury trial, and the presumption of innocence are not technicalities. They are civil rights, and defending someone accused of a crime is how those rights get enforced.
The Supreme Court said it plainly in Gideon v. Wainwright: a fair trial is impossible without a lawyer for the accused. Founding attorney Jason Kosloski spent years as a public defender living that principle, trying cases against the government when the odds were stacked against his clients. That defense experience is the foundation of this firm — the civil rights practice grew out of seeing, case after case, how government power goes wrong and how to fight it.
Defense work and civil rights work are two sides of the same practice. An unlawful traffic stop, a search without probable cause, or a coerced statement is a constitutional violation whether it shows up as a Section 1983 lawsuit or as a motion to suppress. Because we litigate those violations from both sides, we know how to find them in a criminal case — and suppressed evidence is often the difference between a conviction and a dismissal.
We defend Colorado cases the way we litigate everything: prepared for trial from day one. Prosecutors offer better outcomes to defendants whose lawyers they know will pick a jury. If you or someone you love has been charged, the most important step is to say nothing to investigators and talk to a defense lawyer first — the consultation is free and confidential.

Public Defender Roots
Jason Kosloski spent years as a public defender trying cases against the government. This firm was built on that defense-first courtroom experience.
We Know Police Misconduct
We sue officers over unlawful stops, searches, and arrests. That means we know exactly where to look for the constitutional violations that get evidence suppressed.
Clear Flat Fees
Criminal defense cannot ethically be contingency-fee, so we charge clearly explained flat fees — you know the full cost up front, and the consultation is free.
