Colette has over 30 years of experience specializing in energy law, with a focus on the regulation of natural gas services. Her career began at the Federal Energy Regulatory Commission (FERC), where she advanced to acting Assistant General Counsel for natural gas and oil pipeline rate review. In this role, she advised the Commission on critical decisions related to natural gas policies and regulations, including the restructuring of interstate natural gas pipeline services. She also managed litigation involving natural gas and oil pipeline rate and construction cases.

In private practice, Colette represents clients in proceedings before FERC, including matters related to natural gas pipeline rate reviews and construction cases. Her clients include publicly owned electric utilities, whom she advises on fuel supply acquisitions, natural gas transportation services, regulatory developments, and legislative energy issues. She provides tailored insights to help clients navigate evolving energy regulations and their operational impacts.

Earlier in her career, Colette served as a law clerk to a federal appellate judge of the U.S. Court of Customs and Patent Appeals in Washington, D.C., the predecessor to the U.S. Court of Appeals for the Federal Circuit.

Colette holds a Juris Doctor from the Columbus School of Law at The Catholic University of America and a Bachelor of Science in physics from Georgetown University.
