David Concannon is a trial lawyer practicing in the areas of commercial litigation, intellectual property, entertainment, sports and recreation, wrongful death and products liability. 


Mr. Concannon served as a law clerk to Chief Judge Louis C. Bechtle in the U.S. District Court for the Eastern District of Pennsylvania from 1992 to 1995.  His tenure with Chief Judge Bechtle included multiple inter-circuit assignments to try cases in Florida and California, as well as proceedings before the Judicial Panel on Multi-District Litigation.


After his clerkship, Mr. Concannon was associated with Kohn, Swift & Graf in Philadelphia before he founded his own law firm in 2002.  The firm, which became Concannon & Charles in 2016, has a diverse nationwide practice and an international client base.  The firm moved to Ocean City, New Jersey in 2014 and Sun Valley, Idaho in 2017.  Mr. Concannon now divides his time between both offices.


Mr. Concannon has tried numerous cases to verdict in state and federal courts across more than one-third of the United States.  He has not lost a trial since 1995.  Some of his successes include achieving a $3.9 million jury verdict to enforce an oral agreement for the sale of a business, a $3.1 million verdict in a misappropriation of trade secrets case, a $30 million punitive damages verdict in a commercial litigation case, one of the top 50 jury verdicts in the United States in 2005, the second highest jury verdict in Pennsylvania, and one of the highest jury verdicts ever recorded in a tortious interference case.  He has successfully defended hundreds of millions of dollars in claims asserted against the firm’s clients, and his victory in the internationally-televised trial of a wrongful death case in Palm Beach County, Florida was chosen as one of the “Top 10 Defense Verdicts of 2016.”

Mr. Concannon is also an expert in legal issues affecting exploration.  In 2002, he founded Explorer Consulting, a highly specialized consulting practice that advises clients on “the business of exploration,” including organizing and financing expeditions, producing documentaries for film and television, international legal issues, and monetizing intellectual property rights. 


Mr. Concannon has served as General Counsel to several organizations, including The Explorers Club and the X-Prize Foundation.  He has led numerous expeditions, including expeditions to explore the Titanic and to find and recover the Apollo F-1 rocket engines that launched men to the moon.  In 2014, Mr. Concannon and the team he led for Bezos Expeditions' Apollo F-1 Search & Recovery Project were awarded The Explorers Club Citation of Merit for “an outstanding feat of exploration,” the same recognition bestowed upon Dr. Robert Ballard for finding the Titanic in 1985, and to the first American team to summit Mt. Everest in 1963.
