Marshall Dennehey has had a presence in the Lehigh Valley since 1990, when it opened an office in downtown Allentown.  The Lehigh Valley is the fourth largest metropolitan area in Pennsylvania comprised of Allentown, Bethlehem, Easton and their surrounding townships and boroughs.  After 16 years in Bethlehem, Marshall Dennehey’s office is returning to Allentown.  Since its inception, the office has grown on its record of hard work and the successful delivery of strong advocacy and responsive service to our clients.

The Allentown office is staffed with civil defense litigation attorneys who devote their complete professional attention to servicing clients in the Lehigh Valley region and surrounding areas including Berks, Carbon, Lehigh, Monroe, Northampton and Schuylkill Counties. These experienced attorneys have varied practices and focus on matters across the firm's four main departments: casualty, professional liability, health care and workers' compensation.

Led by office managing attorney, Jason M. Banonis, the Allentown office provides our clients with an effective defense litigation team of professionals backed by the intellectual property and broad-based experience of the entire firm, permitting localized and economical representation of insurers and self-insured clients.
