Furman Kornfeld & Brennan

What Furman Kornfeld & Brennan does

Furman Kornfeld & Brennan LLP is a New York-headquartered defense law firm founded in 1999 by three former New York City prosecutors (A. Michael Furman, Neil S. Kornfeld, and Patrick J. Brennan). The firm employs approximately 45-50 attorneys plus professional staff across two offices — Wall Street Plaza in Manhattan and an Armonk/Westchester location — serving clients throughout the New York metropolitan area with pro hac vice reach into New Jersey, Connecticut, and nationwide. FKB's partners collectively bring over 250 jury verdicts and 150+ argued appeals to bear across an 18-practice portfolio, with core concentrations in professional liability defense (lawyers, accountants, other professionals), medical malpractice defense (hospitals, physicians, nursing homes, diagnostic laboratories, dentists, podiatrists), insurance coverage and litigation (including Lloyd's and London market insurers), general liability, construction accident litigation, and cyber security and privacy counsel. The firm also operates a monitoring counsel and program claims administration service that supervises defense counsel across U.S. and foreign jurisdictions for insurance underwriters.

The firm generates revenue through traditional professional services fees — hourly rates and alternative fee arrangements on engagements — sourced primarily from four enterprise customer segments: insurance companies, healthcare organizations, corporations, and individual professionals. Client acquisition is driven by professional reputation, peer referrals, insurance carrier panel placement, bar association involvement (NYSBA, NYC Bar, Defense Research Institute, Professional Liability Defense Federation), CLE instruction, and thought-leadership publications in the New York Law Journal, NYSBA Journal, and PLUS Journal. There is no disclosed investor base, parent company, or external funding; FKB operates as an independent limited liability partnership governed by its equity partners.

FKB's competitive positioning rests on the trial credentials and prosecutorial backgrounds of its founding partners and lateral additions, reinforced by recurring Super Lawyers designations, AV Preeminent Martindale-Hubbell rating, and ABOTA membership. The firm has expanded selectively through partner additions (2014, 2018) and an active associate hiring cycle through 2024-2025, while adding adjacent practice areas such as Cyber Security & Privacy. The April 2026 passing of founding partner A. Michael Furman is a material leadership transition; firm operations continue under the remaining founding partners and broader partnership group.
