Bettina Poirier made history on November 14, 2006, when Sen. Barbara Boxer, D-Calif., the first woman to chair the Senate Committee on Environment and Public Works, named Poirier the first woman to serve as its Staff Director and Chief Counsel. Poirier began her service in 2001 as an advisor to California's junior senator for environmental and agricultural issues. Her time with Boxer, and her nearly two-decade-long career as an environmental lawyer, gives Poirier a deep understanding of environmental and infrastructure issues and the laws that provide the foundation of protection for clean air, clean water, wildlife, and other environmental matters.

Poirier has also served as Minority Counsel to the House Energy and Commerce Committee under Rep. John Dingell, D-Mich. A graduate of Barnard College, Columbia University, and NYU Law School, Poirier was an environmental associate at Skadden, Arps, Slate, Meagher & Flom. She also served as Deputy Assistant General Counsel for Pollution Control in the U.S. Department of Agriculture during the eight years of the Clinton Administration.
