What Ivey, Barnum & O'Mara does
Ivey, Barnum & O'Mara, LLC is a full-service law firm founded in 1950 and headquartered in Greenwich, Connecticut, with additional offices in New Canaan, CT and White Plains, NY. The firm serves both individual and corporate clients across the tri-state region (Connecticut, New York, New Jersey) through seven core practice areas: real estate (residential and commercial transactions, zoning, title), personal injury litigation (car, truck, rideshare, motorcycle, wrongful death, catastrophic and traumatic brain injuries, handled primarily on contingency), trust and estate planning (wills, probate, estate tax, elder law, guardianship), civil and commercial litigation, corporate and business law (formation, M&A, contracts, general counsel), franchise law (loan transactions, sale-leaseback, workouts), and employment law. Its go-to-market is sales-led and relationship-based: the firm markets through attorney profiles, an active legal blog, case-result showcases, and community/bar association involvement, acquiring clients via referrals, professional networks, and reputation in Fairfield and Westchester Counties. The firm's revenue model is professional-services billing, comprising hourly fees, contingency fees on personal injury matters (typically 33% pre-litigation, 40% at trial), and flat fees on certain services; pricing is not publicly disclosed.
The firm operates as a Connecticut LLC with 24 employees and 21 named attorneys, and is differentiated by a small-firm service model with multi-generational client relationships dating to its founding. It has accumulated peer recognition including multiple Super Lawyers designations (Walko, Jones, Port, 2017–2024), Top Verdicts rankings from CT Law Tribune (2015) and New York Law Journal (2014), CBA 100% Club membership, and reported client recoveries exceeding $50 million. As announced on December 22, 2025, Ivey, Barnum & O'Mara is being absorbed into Mandelbaum Barrett PC effective January 1, 2026, ending its operation as an independent entity and joining a multi-state platform with offices in New Jersey, New York, Florida, Colorado, and Connecticut.
