Ansa Assuncao LLP

What Ansa Assuncao LLP does

Ansa Assuncao LLP is a boutique litigation law firm founded in 2009 by former DLA Piper attorneys, including Robert A. Assuncao and O. Daniel Ansa. The firm delivers trial and appellate representation across nine practice areas: Business Counseling, Class Actions, Commercial Litigation, Construction Litigation, Employment Disputes, Insurance Coverage, Personal Injury Litigation, Products Liability / Toxic Torts, and Transportation Litigation. Its primary client base comprises Fortune 500 corporations, international manufacturers, and major organizations facing complex class actions, product liability, commercial disputes, and transportation matters; the firm also serves the State of New Jersey and its agencies as designated Special Litigation Counsel, plus pro se civil rights litigants through federal court panels.

The firm operates as a Limited Liability Partnership from six offices across the Mid-Atlantic, Northeast, and Midwest (New Jersey, New York, two Pennsylvania locations, Maryland/DC, and Ohio). Its technology footprint is conventional: a content-driven website (ansalaw.com), a COVID-19 resource center, and standard professional services communication channels. No API, SDK, proprietary software, or AI tools are referenced anywhere in the firm's materials - the practice runs on attorney expertise, courtroom credibility, and professional networks rather than technology platforms.

Revenue is generated through professional services fees under multiple structures: traditional hourly billing, flat fee arrangements for defined deliverables, contingency arrangements for plaintiff-side and select matters, and hybrid reduced-hourly-plus-success-fee structures. Marketing and client acquisition are sales-led, relying on attorney reputation, peer referrals, industry relationships, thought leadership in legal publications, and earned media in outlets such as the Wall Street Journal, Bloomberg BNA, and NBC Philadelphia. The firm holds AV Preeminent (5.0/5) Martindale-Hubbell ratings, a Fellow designation from the Litigation Counsel of America, and a record of argued matters before the U.S. Supreme Court, Federal Courts of Appeal, and state appellate courts in over 30 jurisdictions.
