Daniel A. Juengel

Daniel A. Juengel has spent more than three decades devoted exclusively to one area of the law: criminal defense. Over the course of that career, he has earned a reputation not only as a skilled trial lawyer, but also as an attorney whose deep understanding of criminal litigation has made him a respected educator, appellate advocate, and mentor within the legal profession.

As a partner at Frank & Juengel Law Group P.C., Juengel represents clients facing some of the most serious criminal charges imaginable, including homicide, federal offenses, white-collar crimes, sex offenses, and other complex felony matters. Whether advocating before a jury or arguing issues on appeal, he approaches every case with the same careful preparation, disciplined analysis, and unwavering commitment to protecting his clients’ constitutional rights.

A Career Dedicated to Criminal Defense
While many attorneys broaden their practice over time, Juengel has spent his career refining his expertise within criminal law.

After earning his Juris Doctor from Saint Louis University School of Law, he focused his practice exclusively on criminal defense, developing extensive experience in both state and federal courts. Over the years, he has represented clients through every stage of the criminal justice process, from investigation and pretrial litigation to jury trials, appeals, and post-conviction proceedings.

That singular focus has allowed him to develop an exceptional depth of knowledge across virtually every aspect of criminal litigation. His work includes death penalty cases, complex federal prosecutions, appellate advocacy, and matters requiring sophisticated legal analysis and strategic trial preparation.

Advancing the Practice of Criminal Law
Juengel’s influence extends well beyond the courtroom.

Throughout his career, he has been a frequent lecturer for continuing legal education programs, teaching fellow attorneys on topics including jury selection, search warrants, cross-examination, expert witnesses, criminal investigations, and trial strategy. His willingness to share practical knowledge reflects both a deep command of criminal law and a commitment to strengthening the profession as a whole.

He has also served in numerous leadership roles within the criminal defense community, including as a life member of the National Association of Criminal Defense Lawyers and the Missouri Association of Criminal Defense Lawyers. His service on the Federal Criminal Justice Act Lead Panel and other professional committees further reflects the confidence that both courts and colleagues place in his judgment and experience.

A Reputation Earned Through Excellence
Among fellow defense attorneys, prosecutors, and members of the judiciary, Juengel has earned a reputation for meticulous preparation, professionalism, and exceptional courtroom advocacy. That respect, developed over decades of practice, is reflected not only in the confidence of his clients but also in the regard of the legal community itself.

His work has been recognized through numerous professional honors, including repeated selection to Super Lawyers, recognition among the Top 50 St. Louis Super Lawyers, an AV Preeminent rating from Martindale-Hubbell, designation among The National Trial Lawyers Top 100, and receipt of the John D. Ashcroft Latshaw Award for Excellence in Criminal Law.
