Danielle O'Neal is a senior associate in King & Spalding’s Houston office and a member of the firm’s Products Liability and Mass Torts practice. Drawing on her scientific background and meaningful trial experience, she represents clients in the chemical, life sciences, pharmaceutical, and energy industries. Danielle is known for translating technical subject matter into clear, compelling advocacy and for partnering closely with clients to craft practical, business-focused solutions tailored to each client’s objectives. 

Danielle brings a unique combination of scientific training, litigation insight, and practical problem-solving to her work on high-stakes product liability and mass tort matters. Her experience spans single-plaintiff actions, consolidated proceedings, and multidistrict litigation, where she has played key roles in developing case strategy, managing discovery, preparing expert witnesses, and supporting trial teams in jurisdictions across the country. Danielle’s ability to understand and distill complex technical concepts—ranging from biological processes to pharmaceutical product design—allows her to collaborate effectively with experts and present sophisticated issues in a clear and compelling manner.

Danielle also draws on her nearly year-long secondment with a Fortune 100 pharmaceutical company, where she worked closely with in-house counsel and business stakeholders on a wide range of litigation and regulatory matters. This experience deepened her understanding of the operational, strategic, and commercial considerations that shape corporate decision-making, and it informs her ability to deliver advice that is both legally sound and aligned with broader business priorities. Her time in-house strengthened her appreciation for efficient communication, cross-functional coordination, and proactive risk management skills she brings to every client engagement.
