Andrew D. Sandroni


Andrew graduated from St. Louis University in 1982 with an A.B. in History and from St. Louis University Law in 1985. Andrew came to St. Louis from upstate New York, married a St. Louis woman, and decided to stay.

He formed the firm of O’Gorman & Sandroni, P.C. with Sean in 1989. The act was not coincidental. Sean and Andrew have known each other since their days as undergrads.

Clients who have suffered a wrong seek Andrew’s guidance through the legal system. Andrew concentrates his efforts on helping clients whose situations have led them to the courtroom. Many probates, domestic and business disputes reach a point when the courtroom is the only forum for resolution. This is where Andrew spends most of his time. Andrew has had the pleasure of litigating cases in Missouri, Illinois, New Mexico and has argued cases before the Federal Court of Appeals in the 8th and 9th Circuits.

Andrew and his well-trained staff help guide clients who are experiencing the trauma of litigation, divorce, or another upheaval through the labyrinth-like procedures.

Andrew is admitted to practice law in Missouri, Illinois, and the Federal Eastern and Western Missouri District Courts.

Father of four children, grandfather of three, still active in Greater Saint Louis Area Council, Gravois District of the Boy Scouts of America as a Scout Leader and is active in his parish
