WILLIAM PAUL DENI, SR., was born in Lambertville, NJ and has continually resided in Hunterdon County, NJ. Mr. Deni attended South Hunterdon Regional High School. After high school he did a post graduate year at Bordentown Military Institute.

Mr. Deni attended Seton Hall University Law School, where he was elected Student Senator of the class of 1972. While a student at Seton Hall, he was chosen to represent the Law School in the prestigious Trial Moot Court competition against other law schools.

During the summers that Mr. Deni attended law school, he was a Law Clerk for the NJ Legislature and also Legal Assistant to the Director of the Motor Vehicles Commission, Ray Marini.

His clients have included doctors, lawyers, Judges, Wall Street executives, business owners, local law enforcement, and NJ State Policemen, and those married to doctors, lawyers, Judges, Wall Street executives, business owners, local law enforcement and NJ State Policemen. Mr. Deni has also been retained to supervise, consult, and act as a co-counsel throughout the United States.

PERSONAL INJURY: Mr. Deni has successfully tried and settled millions of dollars in cases involving accidents, wrongful death, work related injuries, products liability, and medical malpractice.

REAL ESTATE: Mr. Deni has represented sellers and buyers in residential, commercial and industrial real estate transactions and has represented numerous financial institutions as a consultant.

LEGAL CONSULTING: Mr. Deni has served as legal consultant to attorneys and clients for many years. Often contacted for a second opinion, he has assisted parties in all areas of the law. As a former bank review attorney on residential, commercial, and industrial loans, he also was legal counsel to major central New Jersey corporations and has acted as personal attorney to high net worth individuals and companies regarding legal issues on a State and Federal level.

“Law has been my life. Fighting for justice is my daily chore. A satisfied client is my reward.”
