Biographical Details

Gary Siegel was born in St. Louis, and he attended Ladue schools Kindergarten through 12th grade.

Gary graduated from Northwestern University with a degree in journalism from NU’s distinguished Medill School of Journalism. He received a Recognition of Excellence from the Chicago Advertising Club for his work at Northwestern.

Gary graduated from Washington University’s School of Law. In his senior year, he was Second Place Winner in the National Client Counseling Competition. During law school, Gary worked for two years at the law offices of Thomas R. Green.

After passing the bar, Gary worked for George (Buzz) Westfall and then Bob McCulloch of the St. Louis County Office of the Prosecuting Attorney from 1986-1991. By the time Gary left the office, he had completed more than forty jury trials and hundreds of non-jury trials and preliminary hearings.

Since 1991, Gary has practiced in the private sector. In addition to trying hundreds of civil cases, he has gained valuable experience in a wide variety of subjects, serving as a condemnation commissioner for St. Louis County Circuit Court, prosecuting for the City of Creve Coeur and representing the Board of Healing Arts for the State of Missouri.

Probably the greatest honor he has received in the legal profession is his appointment in 2002 by Hon. Stephen N. Limbaugh, Jr. of the Supreme Court for the State of Missouri to serve on a Disciplinary Committee for the Office of Chief Disciplinary Counsel. The OCDC Disciplinary Committee investigates complaints by the public and recommends discipline actions against attorneys. Gary served as Chairman of the Region X Disciplinary Committee until 2016 at which time he “termed out” and his service ended.

Gary takes great pride in saving his client’s money and by finding solutions that avoid litigation. But if a trial is necessary, Gary represents his clients with integrity and zeal.
