Len is a pioneer in the environmental field as one of the first environmental lawyers in the U.S. government, working for the National Air Pollution Control Administration and then as part of the group of federal employees who started the U.S. Environmental Protection Agency (EPA). While at EPA, Len created the structures of the modern-day regulation of air and water pollution, and designed the framework for all of the EPA permit programs. He headed the national water enforcement effort and handled ground-breaking and controversial enforcement cases from Alaska to Idaho to the Caribbean.

In private practice since 1980, Len has represented some of the largest corporations in the world in solving their environmental, health and safety issues, and championed the cause of new companies from the United States, China, Korea and India entering the U.S. agricultural chemical market. He has also represented several industry groups and associations, notably the nylon industry and the asphalt pavement industry in matters requiring innovative solutions to complex environmental, health and safety issues. Len has handled cases involving aldrin/dieldrin, PCBs, dioxins, lead and asbestos. He also has pursued patent infringement actions against some of the largest companies in the telecom industry.

Len has advised Fortune 500 companies, start-up companies, trade associations, international Swiss bankers and venture capitalists. He has a particular interest in the settlement-first approach to conflict resolution, involving coalition formation, alternative dispute resolution and mediation.
