Harvard Law. Former Kirkland & Ellis. Now fighting for plaintiffs in the nation's most consequential mass tort and sexual assault litigation.
Significant results in the cases that matter most
"These victories aren't just legal wins — they're about forcing the most powerful companies in the world to answer for the harm they've caused to the people who trusted them."
The defense's playbook.
Turned against them.
William knows how corporations defend themselves — because he used to be one of the lawyers defending them. After graduating from Yale University and Harvard Law School, he joined Kirkland & Ellis, one of the world's largest and most profitable law firms, where he represented corporate defendants in high-stakes products liability litigation.
Then he switched sides.
Now a partner at Anapol Weiss, William brings that insider perspective to plaintiffs fighting some of the most powerful companies in America. He serves on the Plaintiffs' Steering Committee for the Toxic Heavy Metals in Baby Food MDL and was part of the trial team that helped secure the $8.5 million verdict in Dean v. Uber — the first time a federal jury held Uber liable for a sexual assault by one of its drivers.
