An Exceptional Advocate in Complex Litigation

Our company faced a daunting, multi-district product liability class action that threatened our operations. Steve Koh’s guidance was invaluable. His deep, 16-year expertise in mass tort defense, honed at Perkins Coie, was immediately apparent. He translated complex legal strategies into clear business decisions. Steve’s recognition as a 'Lawyer of the Year' in this field is well-deserved; his approach is both meticulous and pragmatic. He built a formidable defense that led to a highly favorable settlement, protecting our reputation and bottom line. Steve is a consummate professional who inspires confidence at every turn. I recommend him without reservation to any business navigating high-stakes litigation.
