Ron Chapman practices federal criminal defense with a focus on cases that go to trial rather than plea negotiations. He is a partner at Chapman, Dowling & Mallek, a law firm based in Detroit, Michigan. Ron’s practice represents executives, healthcare professionals, business owners, attorneys, and high-net-worth individuals facing federal investigations and white collar allegations nationwide. Mr. Chapman began his career as a federal prosecutor before founding his own firm. He has built a trial record of over 188 federal jury not-guilty verdicts, including a full acquittal in United States v. Bothra. Mr. Chapman treats trial preparation as central to his work, not an afterthought. He handles every case personally, keeps a limited caseload, and gives clients a written litigation risk report early, covering the evidence, the sentencing guidelines, and the real risks and benefits of going to trial. Watch the full video interview above to hear Ron talk about why he built a firm around trying cases, how AI is changing federal prosecutions, and what he wants every client to know before they call him.

Karren Kenney is a federal criminal defense attorney, Certified Fraud Examiner, and founder of Kenney Legal Defense. With more than 30 years of courtroom experience and over 100 jury trials, she represents individuals, professionals, business owners, and corporate clients facing federal investigations and criminal charges throughout California and across the United States. Karren’s federal practice includes complex fraud, health care and hospice fraud, wire and mail fraud, bank fraud, money laundering, conspiracy, public corruption, immigration offenses, firearms cases, government benefit fraud, drug trafficking, and other serious federal crimes. She also represents clients during federal investigations, grand jury investigations, search warrants, pre-indictment negotiations, detention and bond proceedings, plea negotiations, trials, and sentencing. As both an experienced trial lawyer and a Certified Fraud Examiner, Karren is particularly skilled at analyzing financial records, identifying weaknesses in government investigations, and translating complicated evidence into a clear and persuasive defense. She understands that a federal case cannot be defended effectively by focusing only on the indictment. The government’s evidence, investigative methods, witnesses, financial records, and theory of intent must all be tested carefully. Karren believes preparation begins long before trial or sentencing. She works closely with clients to understand their history, family, career, medical circumstances, and the events that led to the case. When sentencing becomes necessary, she develops mitigation as an integral part of the defense strategy, not as a last-minute collection of character letters. Her goal is to present the client as a complete human being while giving the court credible reasons for the most favorable sentence permitted by law. Communication is also central to Karren’s practice. Federal cases can be frightening and overwhelming, particularly for clients and families encountering the criminal justice system for the first time. She makes it a priority to explain what is happening, what the government must prove, and what decisions lie ahead so that clients can participate meaningfully in their own defense. Karren is also the creator and host of the Legal Vixen™ podcast, where she draws on decades of courtroom experience to discuss criminal cases, trial strategy, constitutional rights, and the realities of the justice system. Through candid conversations with attorneys, judges, courtroom professionals, and other guests, she helps listeners understand how the legal system operates beyond the headlines. Karren is licensed to practice law in California, Texas, and Washington, D.C. Her principal office is in Orange County, California, with satellite offices in San Diego and Houston. She represents clients in federal courts throughout California and nationwide.
