Mark Thompson is a member of the three-person Executive Committee, which is the governing body of our 500 lawyer firm and serves to advance and implement its strategic goals and objectives. Since 2008, Mark has also served on the firm's Board of Directors. In addition to his role in the leadership of the firm, Mark has distinct responsibility for the oversight of our 19 regional offices located across Pennsylvania, New York, New Jersey, Ohio, Delaware and Florida.

Mark's legal practice is focused in the areas of corporate, premises and products liability defense with particular emphasis in the theme park and brewing industries. During his career, Mark has defended a variety of clients in high-profile and complex cases. For almost 20 years, throughout Florida and other jurisdictions, he has had the privilege of representing the former Anheuser-Busch Companies, now operating independently as Anheuser-Busch InBev and SeaWorld Entertainment, Inc.

Rated AV® Preeminent™ by Martindale-Hubbell, recognized in 2006, 2007, 2013 and 2014 as a Florida Super Lawyer and in 2012 as one of Florida's Legal Elite by Florida Trend Magazine, Mark is admitted to practice before the Florida Supreme Court, the United States Court of Appeals for the Eleventh Circuit and the United States District Court for the Middle District of Florida. He has tried cases in county, circuit and federal courts and argued before the District Courts of Appeal. In 2010, he represented a client testifying before the U.S. House of Representatives in Washington, D.C.

A graduate of the University of Florida, Mark worked as an insurance adjuster for two years before starting law school. As a law student, he made the Dean's List and was elected to membership of The American Journal of Trial Advocacy, where he authored "Protective Orders: Sword and Shield in the War of Discovery," 12:3 The American Journal of Trial Advocacy (Summer 1989). Mark was also active in moot court and mock trial competitions before graduating from the Cumberland School of Law in 1989. 

After graduation, Mark joined the defense litigation firm of Rumberger, Kirk & Caldwell where he was a partner and practiced for 12 years. In 2001, Mark joined Marshall Dennehey Warner Coleman & Goggin, assuming management of the firm's Orlando office. His responsibilities were increased in 2004 when he was appointed head of the state's casualty practice group and again in 2006 when he was appointed regional managing attorney for the four Florida offices. In 2008, Mark was elected by his fellow shareholders to serve on the firm's nine-member board of directors.
