About me

Born in Philadelphia, Pennsylvania, Mr. Sacks received his Bachelor of Arts degree from Grinnell College (1981) and his Juris Doctor degree from Dickinson School of Law (1984).


He is admitted to practice in all Pennsylvania state courts, as well as the U.S. District Court for the Eastern District of Pennsylvania, and the U.S. Courts of Appeals for the Third and Sixth Circuits.


Mr. Sacks began his legal career practicing personal injury law in Philadelphia. Soon he was also administrating several legal service plans for large labor unions (including Lodge 5 of the Fraternal Order of Police), servicing a collective membership of more than 50,000 members and their families.

In 1994 Mr. Sacks purchased his employer’s assets and launched the present firm. The firm continued to handle personal injury, medical malpractice, and maritime matters. In addition, significant efforts were now devoted to representing plaintiffs in toxic tort and environmental contamination litigation. The direction of the practice changed immediately, as it diversified in order to represent a broader client base.


A satellite firm was formed in New Orleans, closer to the clients whose land had been contaminated. The firm rapidly pioneered N.O.R.M. litigation, eventually resulting in the largest, single-landowner verdict in the nation’s history. We are still one of the country’s leading plaintiffs’ law firms in N.O.R.M. litigation, as well as in other environmental and toxic tort matters.


Within the framework of the new partnership of Sacks, Weston, and Petrelli, Mr. Sacks maintains his dual interests in general practice law and environmental law, with special focus on pursuing litigation against any company or industry that damages the environment or injures property or individuals. He is justifiably proud that he is one of the few U.S. attorneys who has handled two cases in excess of $1 billion and has settled over a dozen cases each for millions of dollars. In addition to pursuing his law-related interests, Mr. Sacks is a member of the Board of Directors of the Philadelphia Tri-State Chapter of the Lupus Foundation of America.
