Legal Experience That Stands Out

Stewart’s litigation practice includes business torts, contract disputes, healthcare, constitutional claims, data breaches, and insurance coverage and bad faith cases. He represents clients in both the state and federal appellate courts and has successfully defended and overturned multimillion-dollar verdicts on appeal. In November 2011, Stewart was elected to a four-year term as Controller for Montgomery County, Pennsylvania. In that role, he oversaw the county’s $400 million in annual expenditures, as well as its $500 million pension fund.

While earning his J.D. at American University Washington College of Law, Stewart served as president of the university’s chapter of the Federalist Society for Law and Public Policy Studies from 2002 to 2003. After graduation, he clerked for President Judge Emeritus Stephen J. McEwen, Jr., of the Pennsylvania Superior Court.

Stewart represents child victims of abuse with the Montgomery Child Advocacy Project and teaches civics classes to sixth graders in our community schools.  Stewart is a former Director of Legal Aid of Southeastern Pennsylvania, a former Director of the Montgomery Bar Association, and a former President of its Trial Lawyers Section.  Previously, he served for six years as a hearing committee member for the Pennsylvania Supreme Court’s Disciplinary Board. He also served as a member of the Upper Moreland Parks and Recreation Advisory Commission and as a Director of the Upper Moreland Free Public Library.
