Litigation Strategy

When clients face class actions, mass actions or individual cases with high exposure, they hire Aaron to team up with litigators and trial lawyers to create and implement the legal strategy to win the case.

Aaron has also defended more than 150 putative class actions and is an editor of the Bolch Judicial Institute’s Guidelines and Best Practices: Implementing 2018 Amendments to Rule 23 Class Action Settlement Provisions (Duke Law School 2018).
