O’Sullivan Reporting is owned and operated by Nancy O’Sullivan, a Certified Shorthand Reporter in Chicago and throughout the Chicagoland area since 1982. Upon graduating from MacCormac Junior College, Nancy began working at Hartnett & Catellani, a large, well-respected court reporting firm in Chicago. After years of extensive experience, including traveling abroad to report depositions on patent case litigation and vast trial experience, Nancy ventured out on her own.

With more than 35 years of working in the legal industry and building her business from the ground up, O’Sullivan Reporting has become a leader in personalized service. Accuracy, dependability, and integrity have been the key to our long-term business success. With our team of experienced and professional court reporters, we continue to build a loyal customer base.
