Criminal Defense

April Preyar is one of the most respected private attorneys practicing in the criminal courts in Cook County. Having been a public defender in traffic courts and in front of Judges Salone and Crane at 26th Street, Preyar developed a reputation for integrity and grit. She brought those skills to the private sector five years ago. 

Preyar has conducted literally thousands of trials and motions before a judge, and dozens of jury trials–ranging from misdemeanors to first degree murder. 

In conjunction with Brendan Shiller, the Shiller*Preyar Law Offices has one of the county’s most formidable duos of criminal defense attorneys. Shiller has conducted jury trials ranging from DUIs to first degree murder. 

In addition to work in the state courts, Shiller is also a member of the Northern District of Illinois’ Federal Defender Panel. Shiller is one of the few criminal defense attorneys that can lay claim to having beaten the federal government in a federal jury trial.
