Colleen Bannon holds the position of director of research & legal information, and is a shareholder at Marshall Dennehey. Colleen still maintains her law practice, which focuses on privacy and data security, where she has represented numerous medical providers, retailers, e-commerce and public entity clients, in data breach actions. She is also experienced in employment discrimination, civil rights and public entity liability defense.

In addition to being a practicing attorney and an administrative director, Colleen also leads our firm's E-Discovery program. Her significant litigation and IT background allow her to work closely with other attorneys in the firm, to provide our clients with cutting-edge legal advice and guidance in this complex and evolving area of law. Colleen is also highly experienced with a variety of other litigation support tools such as Recommind and Access Data's Summation Pro. This deep understanding of technology applications, is significant to Colleen’s employer and business owner clients, particularly when dealing with exposure in privacy and data security.  

Colleen has spoken at numerous conferences, as well as internal seminars, on the topics of electronic discovery in litigation, social media in the workplace, and privacy and data security. Colleen was an author for the Labor Report, a monthly publication of the Pennsylvania Chamber of Business and Industry which features articles on employment law issues including sexual harassment, disability and racial discrimination. 

In 1980, Colleen began employment with Marshall Dennehey Warner Coleman & Goggin as a member of the firm's support staff. While continuing full-time employment with the firm, first as a secretary and then as an applications specialist with the firm's IT department, Colleen obtained her Bachelor of Arts degree, magna cum laude, from Holy Family College in 1992.
