Integrity, service, innovation, and the highest level of professional expertise are the hallmarks of William H. Connolly & Co., LLC. Throughout the course of over sixty years since Bill Connolly Sr. opened his one-man office in Newark, New Jersey, the company has grown and diversified to become one of the most highly respected full-service insurance brokerages in the area. We are proud of our success and, most of all, our continued commitment to providing the best insurance products and the most professional service at competitive prices.

William H. Connolly & Co., LLC serves the insurance needs of a large and diverse group of businesses, not-for-profit institutions, professional services and individuals. Our investment in information technology has extended our reach to serve clients not only in the metropolitan area but around the world. Our technological services staff keeps us on the cutting edge of our industry, enabling us to serve our local and international clients most efficiently.

The Company's growth is due largely to its reputation for excellence and integrity and its ability to meet the evolving needs of our clients. Many of our commercial customers began with us shortly after World War II and are now, like us, industry leaders. For our newer customers- technology driven manufacturers, health-care institutions, biotechnology businesses and service industries- we have also provided the specialized risk management services and innovative insurance coverages they need.

Aggressive and innovative in our pursuit of the solutions to insurance and risk management problems, William H. Connolly & Co., LLC is widely recognized for our expertise in complex Employment Practices Liability, Directors and Officers Liability, and Worker's Compensation issues. Because we are among the largest producers placing business with both national insurance companies and strong, regional carriers, we negotiate from a position of strength for our clients.

We take great pride in the long-standing relationships we have with our clients. We regard each of our clients as unique and serve them with utmost attention and professionalism. We would welcome the opportunity to have you become one of them.
