"I have been responsible for managing and resolving complex litigation involving mass tort, commercial, and property damage claims valued into the millions of dollars over the course of my career. My clients trust me to resolve their disputes in an efficient, cost-sensitive, and creative manner while keeping them informed at all times of the status of the lawsuit and the risks presented."

Over many decades of practice, Alan earned his impressive track record of favorable outcomes in defending class actions and mass torts asserting claims of long-term exposure, air releases, and groundwater and/or soil contamination.  

Sine legacy litigation began nearly three decades ago, Alan has successfully defended these high-stakes claims – often valued from tens to hundreds of millions of dollars in dispute – for Fortune 5 to 500 companies. Alan has developed effective short- and long-term tactical legal strategies which lead to outcomes in his client’s favor. These strategies then impact the entire docket of other legacy claims going forward.
