Located in St. Louis, Missouri’s historic Soulard neighborhood, the O’Brien Law Firm is an award-winning mesothelioma law firm with extensive experience litigating asbestos exposure cases. We represent workers and their families suffering from mesothelioma and other diseases related to asbestos exposure.

Founder Andrew O’Brien moved to St. Louis from Ireland in 1990, where he was a practicing lawyer. He began assisting a prestigious local law firm with asbestos cases while he worked toward his American law degree from Saint Louis University.

After becoming a licensed attorney in Missouri and Illinois in 1994, Andrew took over primary responsibility for handling all asbestos cases at this local firm.

By 2000, there were significant changes in the legal landscape that presented major hurdles to obtaining adequate compensation for asbestos victims. Andrew believed that a firm needed to be created that focused solely on asbestos cases so that those challenges could be met successfully for future clients. With that vision, he formed the O’Brien Law Firm in September 2000. The firm has been delivering premier legal service to asbestos victims ever since.



In 2001, the Missouri Bar Foundation presented Andrew O’Brien with the prestigious Lon O. Hocker Award for “outstanding trial work by young lawyer members of The Missouri Bar.” Only three Missouri lawyers receive this award every year. Andrew was selected for his extensive record of successful asbestos litigation.
