Sills Cummis & Gross P.C.

Founded in 1971, Sills Cummis & Gross has established an outstanding global reputation. Our growth has been made possible by a large national client roster and an ever-expanding list of international corporations. The Firm was featured in Chambers USA Guide to America's Leading Lawyers for Business which ranked the Real Estate, Bankruptcy and Health Care practices first in New Jersey and the Corporate, Litigation, and Employment and Labor practices in the top three in the State in the 2009 edition.

Our growth continues because Sills Cummis & Gross is more than just a law firm. It is a think tank for the industries that choose us. We go beyond what is expected of a law firm by partnering with our clients and taking an insider’s view of each client’s business.

On a national level, our lawyers represent companies from Fortune 500 to emerging growth. On an international level, we are frequently called upon and have been focusing on cross-border transactions with non-U.S. companies doing business in the U.S. As a full-service firm, our clients have access to all of our practice groups, thus alleviating the need to bring in other consultants when ancillary issues arise.
