Frequently Asked Questions

01What areas of Missouri and Illinois does Wittner Law serve?

Wittner Law represents clients throughout the State of Missouri and the State of Illinois. We regularly handle matters across the greater St. Louis metropolitan area, including St. Louis County, St. Charles County, Jefferson County, and Franklin County, as well as Central and Southern Illinois, including Madison County, St. Clair County, Sangamon County, and Macoupin County. Greg Wittner is also admitted to multiple federal district and circuit courts and can represent clients in federal cases in those jurisdictions.

02What types of criminal cases does Greg Wittner handle?

Greg Wittner focuses exclusively on criminal defense. Practice areas include assault, child pornography, computer crimes, conspiracy, drug offenses, DWI and DUI charges, expungements, fraud, juvenile crimes, murder, sex crimes, theft, traffic violations, weapons offenses, and white collar crimes. The firm also advises on corporate governance and compliance matters that intersect with criminal exposure.

03Does Wittner Law handle both state and federal cases?

Yes. Greg Wittner is licensed in both Missouri and Illinois state courts and is admitted to practice in multiple federal courts, including the U.S. District Courts for the Eastern and Western Districts of Missouri, the Southern and Central Districts of Illinois, the Eastern District of Texas, and the Northern District of Ohio, as well as the U.S. Courts of Appeals for the D.C. Circuit and the 5th Circuit. This dual state and federal experience matters because federal criminal cases follow a different set of rules, sentencing guidelines, and procedural timelines than state cases.

04What should I do if I've been arrested or am under investigation?

Speak with an experienced criminal defense attorney before answering questions from law enforcement. In the United States, you have the right to remain silent and the right to an attorney. Exercising both protects you regardless of the underlying facts. Do not consent to searches, do not discuss the case with anyone other than your attorney, and preserve any documents, messages, or recordings that may be relevant. If you are in Missouri or Illinois, contact Wittner Law at 314.406.5006 to discuss your situation directly with Greg Wittner.

05How do I schedule a consultation with Greg Wittner?

To discuss your case with Greg Wittner directly, call 314.406.5006 or send a message using the contact form on this page. Greg will follow up to arrange a confidential consultation and discuss next steps based on the specifics of your matter.

06How quickly can I speak with an attorney after I reach out?

Wittner Law prioritizes responsive, direct communication with every client. Greg or his team will return your message as soon as practicable. For time-sensitive matters such as an active arrest, an upcoming arraignment, or notice of a federal investigation, please call 314.406.5006 directly so we can respond quickly.

07How are your legal fees structured?

Fee arrangements depend on the type, complexity, and stage of the case. Greg Wittner will discuss the fee structure, retainer expectations, and likely scope of work transparently during your initial consultation, so you know what to expect before retaining the firm.

08Can you help me get a criminal record expunged in Missouri or Illinois?

Yes. Expungements are a listed practice area at Wittner Law. Eligibility, waiting periods, and the petition process differ significantly between Missouri and Illinois law and depend on the specific charges, dispositions, and your post-conviction history. Greg can review your record and explain which offenses, if any, may be eligible for expungement or sealing, and what the process will look like in your jurisdiction.

09Do you defend juvenile cases?

Yes. Wittner Law represents minors in juvenile court proceedings, including delinquency matters, school-related offenses, and certification hearings where prosecutors seek to try a juvenile as an adult. Because juvenile records and certification decisions can affect a young person's education, employment, and future opportunities, early representation is important.

10What makes Wittner Law's approach different from larger criminal defense firms?

After more than three decades practicing criminal defense, including six years at Rosenblum Schwartz Fry & Johnson, Greg Wittner launched WITTNER LAW in July 2024 with a deliberately client-centric model. Rather than carrying a high-volume caseload, the firm intentionally preserves the capacity to give every client direct access to Greg and a defense strategy built around the specific facts of their case, not a templated approach. Greg also maintains an AV rating with Martindale-Hubbell and is a member of The National Trial Lawyers Top 100 Criminal Defense Attorneys (Missouri).
