Although he has been a litigator for nearly 40 years, for more than 35 years Steve has specialized in the defense of complex personal injury, property damage, and products liability claims. He has represented manufacturers of chemicals, pharmaceuticals, medical devices, and machinery in hundreds of state and federal court actions and in alternative dispute resolution proceedings. From 2000-2005 he served as Managing Partner of Barg Coffin Lewis & Trapp, LLP. Steve’s litigation and trial practice has been built on a commitment to excellence and client service, attention to detail, and the ability to apply sound common sense toward resolving complex lawsuits efficiently and cost effectively. His clients find his style flexible, accessible, and responsive.

Practicing environmental law gives me the opportunity to regularly work with great clients and great lawyers to solve complicated problems. In the course of helping our clients, I welcome the challenge of helping clients avoid litigation where possible, defending them from personal injury and property damage claims, continually evaluating emerging scientific and medical developments, and balancing public policy and environmental protection concerns.
