Central New York Law Firm Committed to Clients Since 1987

The attorneys at Sonneborn, Spring & O’Sullivan, P.C. are committed to excellent representation in a number of legal fields:

• Our primary Personal Injury attorneys, Patrick J. O’Sullivan  and Irwin Birnbaum, represent severe and catastrophic injury victims who need financial compensation and emotional support due to the pain and suffering caused by someone else’s negligence.
• Our principal Employment Law attorney, Laura L. Spring , has spent almost 20 years representing employees in legitimate claims of mistreatment and employers in defense of illegitimate mistreatment claims. She also provides employers with valuable proactive advice to help prevent future ethical and/or legal problems.
• Our principal Business and Commercial Law attorney, James L. Sonneborn, has worked for more than 25 years in the areas of commercial litigation, business transactions, corporation formation, and legal counsel. He assists both large and small businesses in securing their legal rights, securities brokers in making job transitions, and consumers in navigating securities arbitration issues.

Founded in 1987 by James L. Sonneborn, our law firm has had a number of large successes locally, regionally and across the state. Past cases have involved million-dollar awards in personal injury cases; large-scale employment litigation against such opponents as General Electric and CNY Centro; representation of large, multi-national financial institutions; and resolution of stressful family problems for countless members of the Central New York community.

Our lawyers have a tremendous reputation for responsive, detail-oriented service to a select group of clients. Our commitment to excellence requires taking only cases that we truly believe in, and emphasizing quality of work over quantity of clients.

Community Service Is Part of Our Mission

We are also actively involved in the Syracuse community. Our attorneys and their families work at soup kitchens during Christmas, raise money for mental health and the arts, coach youth sports teams, serve on the boards of numerous area non-profit organizations, and advocate on behalf of preserving the Adirondacks. We believe that in both our law practice and our community service, we can make a positive contribution to the lives of our clients, friends and neighbors.
