Mr. Mason has a broad employment law and civil litigation practice and counsels businesses and educational institutions, both large and small, in dealing with a wide range of employment disputes, ranging from claims brought by employees and former employees under federal and state employment laws to issues involving compliance with employee non-competition, non-solicitation and confidentiality restrictions.  David also has extensive experience litigating complex cases in state and federal courts as well as arbitral bodies, primarily focusing on contract and business tort (unfair competition, theft of trade secrets, etc.) disputes and matters related to internal corporate governance.  In addition, David has assisted clients in conducting internal investigations and responding to governmental regulatory investigations.

Before joining Ogletree Deakins, David practiced employment law and litigation at a major national law firm and a boutique litigation firm in the Boston area.  David also served as a Special Assistant District Attorney in the Middlesex County District Attorney’s Office, handling a diverse criminal caseload and representing the Commonwealth of Massachusetts in the trial courts on a daily basis, including many trials and evidentiary hearings.  His service after law school as a law clerk to the Honorable George A. O’Toole, Jr. in the U.S. District Court, District of Massachusetts, gives David a unique and in-depth insight into the litigation process.
