In one case, after a six-day trial, client obtained an injunction permanently prohibiting a zoo from possessing any endangered or threatened species. In another case, after a two-day evidentiary hearing establishing a zoo’s egregious discovery violations, client obtained a default judgment and permanent injunction against zoo, dismissal of the zoo’s counterclaims with prejudice, and award of reasonable attorneys’ fees and expenses for discovery violations the District Court described as “brazen” and “confounding.”

- Defended an executive and former general counsel of a major public health care insurance company in connection with federal health care fraud charges.

- Represented a publicly traded company in a tortious interference lawsuit and client obtained fees and costs in the defense.
