Prior to joining Marcus & Shapira in 2012, Jon worked for several years in New York City at the largest law firm in the country devoted solely to business litigation. Jon then joined a global full-service law firm in Washington, D.C., where he gained additional experience before becoming a Trial Attorney for the United States Department of Labor. As a member of a task force hired to tackle a massive backlog of safety violations, Jon negotiated favorable settlements of nearly 150 cases within eight months and successfully argued at trial that a monetary penalty assessed against a large mine operator should be multiplied eightfold.
