Shannon concentrates her practice exclusively in workers' compensation, representing trucking companies, restaurants, construction companies, candy manufacturers, boroughs/municipalities, colleges, hospitals, agricultural businesses, distribution centers and staffing agencies in all manner of matters related to workers' compensation. She takes a hands-on approach to working with clients, actively engaging them in an open dialogue regarding topical issues relevant to their business. Shannon works closely with employers to develop policies and procedures to reduce workers' compensation exposure and to educate them on the Workers' Compensation Act.
Shannon also devotes a portion of her practice to representing boroughs and municipalities. She works together with their solicitors and actuaries to coordinate case strategy and to reach the best outcome for the employer.
In recognition of her exemplary work as a defense attorney, Shannon was recognized as Pennsylvania's 'Lawyer of the Year' for Workers' Compensation Law - Employers in Harrisburg for 2022 and 2024.
Shannon graduated cum laude with a Bachelor of Arts degree from the University of Delaware, where she was also admitted to the Phi Beta Kappa honor society. In 1996, she received her juris doctor from The Dickinson School of Law. Following law school, Shannon served as a law clerk for several Workers' Compensation Judges in Harrisburg, Pennsylvania.
