Our Firm


The Cotsirilos Firm has nine attorneys. We are small by design to provide our clients better and more personalized service. When you hire us, you get us – partner level judgment and experience, not a cadre of associates who know nothing about you, your business, or your case. We dedicate a highly talented and focused team to tackle and solve your problem, no matter how big or small.

We are trial lawyers. Each and every lawyer in the Firm has tried a case – even our associates. The depth of our trial experience enables us to properly assess the ultimate strengths and weaknesses of any case, quantifying clients’ risks more accurately than our competitors.

We understand your business. We are problem solvers, and no dispute can be resolved or advice given if your lawyers do not understand your business goals. We work hard to understand a client’s particular business and industry in order to get the best result for your business.

We dig deeper. You count on your lawyer to understand the law, but that’s only half of our job. Facts and evidence drive outcomes, and with three former prosecutors on our team, we bring more investigative skills to the table than any firm our size.

We are creative. The standard playbook doesn’t always work. Our lawyers attended the best law schools in the country, and we bring a high-energy, high-intellect approach to every matter, crafting creative strategies and solutions for each client’s unique case.

We get results. Founded in the 1950s by George Cotsirilos, we were among Chicago’s first white-collar criminal defense firms, and over 60 years later, we are still among the best. We have earned our reputation for excellence and quality by achieving successful outcomes for clients year after year.

We care about our clients. Hiring a lawyer is an act of trust. We understand that, and we take it seriously. We see our clients through some of the toughest challenges in life – from contentious battles over the destiny of their businesses to criminal indictments. This kind of work requires a personal investment in our clients, and we are dedicated to earning our clients’ trust.
