Dan deploys more than two decades of environmental litigation experience to resolve clients’ legal and business challenges.

Primarily focused on environmental, toxic tort, and product liability litigation, Dan helps clients successfully resolve groundwater contamination, hazardous waste site remediation, natural resource damages, permit defense and product-related matters. He enjoys using his skills as a litigator to help clients solve environmental problems.

Among his many wins, Dan successfully led a team that defeated an emergency challenge to a permit that Dan’s client needed to continue its operations. The favorable result that Dan and his trial team achieved allowed the client to avoid losing millions of dollars’ worth of production.

In a toxic tort case involving an alleged international conspiracy, Dan led a successful briefing effort that resulted in early dismissal of all claims against his clients, saving them from protracted litigation and protecting their reputation.

Dan is a lead member of the B&D team defending product liability and toxic tort claims in a multi-district litigation, which has spanned more than 100 cases and billions of dollars in claims, regarding the use of a gasoline additive.  In that capacity, Dan helps lead large teams of lawyers and experts across multiple cases and jurisdictions.

Dan is also an experienced CERCLA litigator.  He currently leads one of the firm’s advocacy teams defending a client at one of the largest CERCLA sites in the country.

While focusing his practice on litigation, Dan also provides practical and actionable advice designed to minimize environmental risk and potential liabilities. 

An active member of various bar associations, Dan is a past chair of the American Bar Association’s Environmental Litigation and Toxic Torts Committee, and currently co-chairs the New York State Bar Association Environment Section’s Toxic Torts Committee. He also is a member of B&D's Management Committee and Managing Principal of B&D's New York office.

Before joining B&D, Dan served as a law clerk for The Honorable Carlos R. Moreno, U.S. District Judge for the Central District of California. Prior to attending law school, Dan served as editor-in-chief of the environmental news service Greenwire.
