What Duffy & Duffy, PLLC does

Duffy & Duffy, PLLC is a New York-based plaintiff's law firm founded in 2001 by James Duffy and his son Michael Duffy, specializing in medical malpractice, personal injury, birth injury, nursing home abuse, brain injury, and mass tort litigation. The firm operates from a headquarters in Uniondale (Long Island) at 1370 RXR Plaza and a newer Bronx office at 388 Canal Place opened in December 2025, serving all five NYC boroughs, Long Island (Nassau and Suffolk Counties), and Westchester County. Its case portfolio includes landmark verdicts such as a $109M brain-injury malpractice verdict and an $80M birth-injury verdict against Jacobi Medical Center, with cumulative client recoveries exceeding $1 billion across 250+ malpractice settlements and 70+ multi-million dollar recoveries. The firm is staffed by approximately 19 partners plus associates, including medically credentialed attorneys such as Mary Anne Walling (RN, BSN, MSN, JD), giving it in-house capacity to evaluate complex medical evidence.

The firm generates revenue exclusively through contingency fee retainers: clients pay no upfront fees, and the firm recovers attorney fees only upon a successful outcome. Marketing and client acquisition run through a multi-channel mix including its website, blog, YouTube videos, a podcast, and active social media accounts on Facebook, X, LinkedIn, Instagram, and TikTok, supplemented by earned media coverage (NY Daily News, NY Post) and community philanthropy. Distribution relies on direct consultation (in-office, phone, online contact form) and referrals from prior clients, healthcare providers, and community networks. The firm has no proprietary technology platform, no public API, and no disclosed AI tooling — operations are built around attorney expertise, expert witness networks, and trial-readiness rather than technology automation.
