About Mary Jo B
Mary Jo B Gilsdorf earned her undergraduate degree in fine arts from the University of Delaware in 1980 and went on to receive her J.D. from Villanova University School of Law in 1989. Her academic path combined a liberal arts foundation with legal training, setting the stage for a career that moves between practice, dispute resolution and in-house legal work.
Early in her professional life she worked in the construction sector. In 1997 she served as a generalist at Ehret Construction Company, a role that exposed her to practical business and legal issues in the field. A few years later she transitioned to an in-house post, taking the title of Director of Legal Services at L. F. Driscoll Co., LLC in 2000. Those positions gave her direct experience handling the kinds of transactional and operational matters that companies confront.
In 2014 she opened Gilsdorf Law, LLC and remains listed as owner. The firm provides legal services to a range of clients. Over time her work at the firm has intersected with alternative dispute resolution, reflecting a steady involvement in arbitration and mediation roles outside the courtroom.
She is admitted to practice in Pennsylvania, the District of Columbia and New Jersey. Alongside her bar admissions she has been active in professional organizations. She joined the American Bar Association in 2012. She holds memberships in the Pennsylvania Bar Association beginning in 2015 and in the Chester County and Delaware County bar associations since 2014. Those memberships place her in regular contact with peers across multiple jurisdictions.
Her arbitration credentials are notable in her professional record. She has served as an arbitrator for the American Arbitration Association since 2013 and as a mediator for the same organization since 2015. Those roles involve hearing disputes and facilitating negotiated outcomes for parties who choose arbitration or mediation over litigation.
Colleagues and clients see a lawyer comfortable in both advisory and neutral roles. Her background includes in-house counsel work, private practice and service as an arbitrator and mediator. She continues to operate Gilsdorf Law, LLC and to take assignments from the American Arbitration Association, handling arbitration, mediation and general legal matters for clients in Pennsylvania, the District of Columbia and New Jersey.
