Thomas M. Gribbin, Jr.

An associate in the Philadelphia and New Jersey offices of Willig, Williams & Davidson, Thomas M. Gribbin, Jr. focuses his practice on the representation of both private and public sector labor unions and individual employees.  An experienced labor law attorney, Tom routinely advocates for clients in grievance and interest arbitrations, mediation, administrative proceedings and before state and federal courts. Prior to joining the firm, Tom practiced labor law at another union-side labor law firm representing a wide range of public safety, service and trade unions.

Tom hails from a proud labor family and has been actively engaged in the labor movement, working on numerous political campaigns since high school in order to advance the issues of working men and women, including working for Working America, the political organizing branch of the AFL-CIO, during the 2006 midterm elections.

After receiving a degree in Political Science from Villanova University in 2002, where he was also the recipient of the Villanova Student Leadership Award, Tom obtained his law degree from Duquesne University School of Law in 2006.  While in law school, Tom was a member of the Tax Moot Court Team and Honor Society.
