Jeffery R. Mullen focuses his practice on construction law. Before becoming an attorney, Jeff worked for a regional contractor as a project manager, where he oversaw various residential, commercial, and public projects. Building upon that experience, Jeff’s practice is focused exclusively on the construction industry to assist clients in addressing the specific challenges they face before, during, and after project completion.

He has experience representing clients in disputes arising from a wide array of construction projects, including power plants, mass transit systems, highways, pipelines, dams, and commercial and residential building.

In addition, Jeff counsels clients through contract formation and performance to identify, avoid and resolve disputes as a means of preventive risk management. He has experience drafting and negotiating design and construction contracts and proposals for projects ranging from commercial and residential renovations to major infrastructure improvements.

Jeff does pro bono and community work serving as trial counsel in cases ranging from the prosecution of prisoner civil rights matters to protecting the legal rights and interests of the elderly in the Greater Philadelphia Area against contractor fraud.
