After working together to serve the people of Illinois for more than eight years as prosecutors in the State’s Attorney’s Office in Cook County, Peter O’Mara and Sean O’Callaghan joined together in 2013 with a vision for a different kind of law firm. Today, the firm of O’Mara & O’Callaghan takes a collaborative and honest approach to counseling and litigating for our clients. We are leaner, more responsive, and more aggressive than other law firms. Our model is designed to resolve disputes for businesses and individuals in the timeliest and most cost-efficient manner possible. We find the quickest path to victory and pursue it vigorously for our clients. While avoiding trial is frequently the best business decision, we are not afraid to take a case into the courtroom – and we know how to win when we are there.
