Glasgow & Olsson: A Law Firm Built on Experience, Reputation, and Results

At Glasgow & Olsson, legal representation is about expertise, strategy, and a reputation for excellence. Our attorneys have built their careers in the courtroom, earning the respect of judges, prosecutors, and legal professionals across Illinois. Whether you are facing serious criminal charges, complex family law disputes, or high-stakes civil litigation, our firm is known for delivering results in cases where experience and reputation matter most.

A Prosecutor’s Insight, A Defender’s Tenacity

Before founding his firm, Thomas T. Glasgow spent years as a Cook County State’s Attorney, prosecuting cases ranging from DUI and multi-kilo felony narcotics to first-degree murder. From 1994 to 1998, he worked in the Traffic, Narcotics, Juvenile, and Felony Review Divisions, trying both misdemeanor and felony cases before juries and judges. His time in the prosecutor’s office gave him firsthand insight into the strategies used by the State, an advantage that now empowers his clients in criminal defense cases.

“I became a State’s Attorney because I wanted to help people. But the criminal justice system is often a revolving door. As a defense attorney, I have been able to change more lives than I ever could as a prosecutor. Now, I fight for my clients with the same intensity I once prosecuted cases—because I know what’s at stake.”

Thomas T. Glasgow

At Glasgow & Olsson, we don’t just defend cases—we shape outcomes. With decades of experience and a track record of success in state and federal courts, our firm provides legal representation that is respected, formidable, and unmatched in depth of knowledge.

A Strong Advocate in Complex Family Law Matters

Family law requires not only legal skill but also a firm grasp of financial, business, and personal dynamics. Attorney Stephanie Olsson is known for her sharp litigation skills and strategic approach to domestic relations cases, handling high-asset divorce, business valuations, special needs child custody issues, and high-conflict parenting disputes.

Her background in criminal law allows her to bring a powerful and decisive approach to divorce and family litigation, ensuring her clients are protected, informed, and well-positioned for the best possible resolution.

“Domestic relations cases are deeply personal. My job is to listen, to understand a client’s goals, and to navigate the litigation process with clarity and precision. Each client has a voice in their case, and my role is to ensure that voice is heard in a way that leads to the best outcome.”
