Simpson Thacher & Bartlett LLP is home to battle-tested litigators who thrive in high-stakes business conflicts, complex financial and securities matters, bankruptcy-adjacent disputes, and hard-fought insurance coverage battles. At the helm are global co-chairs Lynn Neuner, a go-to strategist for commercial litigation, insurance coverage, and bet-the-company disputes, and Jonathan Youngwood, who represents issuers, boards, and financial institutions in securities and shareholder litigation, with extensive experience in carrying cases through to appeal. Bryce Friedman, co-head of the business litigation practice and head of the insurance litigation practice, concentrates on insurance coverage and policyholder-insurer disputes, while Michael Garvey, also co-head of business litigation, is recognized for steering sophisticated commercial and financial disputes. Supporting this platform, Linton Mann brings incisive judgement in securities and shareholder litigation, breach of fiduciary duty matters, and fraud-related cases. The team recently added to its capabilities: in January 2025, Amy Candido arrived as head of IP litigation; while in May 2025, Laura Brett joined to lead the advertising advisory and litigation practice. All the above-mentioned litigators are based in New York.

Testimonials
Collated independently by Legal 500 research team.
- Every time that I have used Simpson, I get the right team for the job. The "team" is also lean, which I appreciate. For many of my matters, I have one primary partner and one associate. When necessary, additional associates/partners are added, but that's an exception, not the norm. I know and feel comforted that I can come to Simpson with my most challenging matters - whether that's complex legal issues or complicated reputational risk.
- Jon Youngwood is a master strategist and advocate. Both his written work and oral advocacy are top-notch.
