Irving Seidler

Irving Seidler is a Schaumburg criminal defense attorney who has represented clients facing criminal charges in the area since 1978. His work includes felony and misdemeanor cases, juvenile matters, DUI and DWI charges, drug offenses, and other criminal proceedings. Before entering private practice, he served as an Assistant Cook County Public Defender. That background gave him early experience defending accused people and working directly in criminal courtrooms.

Irving graduated with honors from Chicago-Kent School of Law in 1974. His legal education was followed by service in the Cook County Public Defender’s Office, where he developed practical experience with criminal procedure, evidence, trial preparation, and client defense. The combination of formal legal training and public defense work provided a foundation for the private criminal defense practice he has maintained for decades in Schaumburg and the surrounding Illinois communities.

Irving evaluates and defends cases involving serious felonies, misdemeanors, DUI and DWI allegations, juvenile charges, immigration-related criminal concerns, and drug offenses. His firm also handles other legal matters, but criminal defense remains central to his individual practice. His long courtroom background allows him to assess the prosecution’s case, identify factual and legal issues, prepare defenses, and advise clients about the consequences and procedural choices that arise at each stage.

Irving Seidler brings more than four decades of criminal defense experience to clients facing charges in Illinois. His career began in public defense and continued in private practice, giving him sustained exposure to criminal investigations, negotiations, motions, and trials. He focuses on protecting clients’ rights and addressing the practical consequences of criminal allegations while using extensive courtroom experience to prepare cases involving offenses ranging from traffic-related charges to serious felonies.
