Charged with a crime
in Missouri?
Charges put your liberty, your record, and your livelihood on the table. You need counsel who has worked the other side of the courtroom — and who knows exactly how the State builds these cases. David L. Naumann was a St. Louis County Assistant Prosecuting Attorney before he opened the firm in 1979. Forty-nine years later, he uses that vantage point to defend Missouri clients facing every category of criminal charge.

The difference
an experienced lawyer makes.
A Former Prosecutor Sees the Case Differently
David spent the first two years of his career prosecuting cases for the St. Louis County Prosecuting Attorney's Office. He knows what the State is looking for, what they will overcharge to leverage a plea, and where their proof problems usually live. That perspective changes how a defense is built — from the first phone call.
Six Years on the Bench Sharpens the Argument
Between 2001 and 2007 David served as a Missouri Municipal Judge. Knowing how a judge actually weighs evidence, reads suppression motions, and decides credibility is not academic. It is the difference between an argument that works and one that does not.
Court-Tested Counsel Gets Better Plea Offers
Carriers and prosecutors track which firms try cases and which firms always settle. The firms that try cases get better offers because the alternative is jury risk. Even cases that ultimately resolve by plea benefit enormously from being prepared as if they will go to trial.
Personal Attention From Day One
The firm is led by David L. Naumann — supported by a small staff. Your case stays with one attorney from the first meeting through the last filing. No transferred files mid-case, no anonymous junior staff billing time on your matter.
What happens
when you call us.
Confidential Intake
A free phone or office consultation to understand the charge, the procedural posture, and the bond conditions. Same-day callbacks during business hours.
Discovery & Investigation
We obtain the police report, body-cam and dash-cam footage, witness statements, lab reports, and all discovery the State is required to disclose.
Motion Practice
Where the law supports it, we file motions to suppress evidence, motions to dismiss, motions in limine, and any other pretrial relief that improves your position.
Negotiation or Trial
Most cases resolve through negotiation. The cases that should not are tried. Either way, the strategy is built around what is best for you, not what is convenient for the firm.
Frequently asked
questions.
Fees vary by case type and complexity. We quote our fee clearly, in writing, at the initial consultation — before you commit. Misdemeanors are usually flat-fee. Felonies and federal cases are typically priced based on the work required to defend them properly. The first conversation is free.
Missouri felonies are punishable by more than one year in prison and are graded Class A (up to life) through Class E (up to 4 years). Misdemeanors are punishable by up to one year in county jail and graded Class A (up to 1 year), B (up to 6 months), C (up to 15 days), or D (fines only). Felony convictions also produce greater collateral consequences — voting rights, firearm rights, employment screening — than misdemeanor convictions.
Almost never, before talking to a lawyer. The Fifth Amendment exists because anything you say can and will be used against you. Polite, brief refusal — "I would like to speak with my attorney before answering any questions" — is the right answer in nearly every situation.
Often, yes. Successful pretrial outcomes include outright dismissal (insufficient evidence, suppression of key evidence, prosecutorial discretion), reduction to a lesser offense, diversion programs, and Suspended Imposition of Sentence (SIS) outcomes that ultimately produce no conviction. The earlier we are engaged, the more leverage we have to negotiate one of these outcomes.
You may qualify for a public defender. The Missouri Public Defender system provides representation in cases where the defendant meets the financial eligibility threshold. We are happy to refer you to the appropriate office. For those who do not qualify but cannot pay full fees up front, we offer payment plans for many cases.
Misdemeanors typically resolve in 60–180 days from filing. Felonies usually take 6–18 months, and complex cases (federal, multi-count, expert-heavy) can run longer. We give realistic timelines at the initial consultation based on the specific facts of your case.
