In addition, Jennifer has substantial experience handling high-stakes commercial disputes in areas such as: breach of contract, business torts, fiduciary duty and derivative claims, executive compensation, covenants not to compete, trade secrets, retaliation, whistleblower claims, dealer agreements, alleged fraud, and claims under the federal securities laws and Racketeer Influenced and Corrupt Organizations (RICO) Act. She has particular experience resolving commercial disputes in areas subject to extensive state or federal regulation.
