We have been providing comprehensive legal solutions for Southeastern Pennsylvania clients since 1955.

Comprehensive Solutions

With a large and diverse team, we can handle problems that cross over into multiple legal areas. Further, we can recognize problems in other legal areas that many single-practice firms might not see.

We are here to give you the peace of mind that comes from knowing your legal concerns are covered.

Your Local Law Firm

Our law firm started all the way back in 1955, when William O'Donnell, Jr., Alvin L. Weiss and Emidio J. Mattei first put up our shingle in Pottstown. Since then we have grown to fourteen attorneys, a dedicated group of assistants and paralegals, and a second office in Phoenixville, Pennsylvania.

All of our lawyers share the same dedication to being the hometown law firm for all of Southeast Pennsylvania.
