A first-chair trial lawyer and former First Assistant Attorney General in Louisiana with three decades of private sector and top government experience spanning complex civil and white collar litigation, state attorneys general enforcement, and crisis management of high-profile environmental disasters—including Louisiana’s Deepwater Horizon response—Trey is a trusted counselor to senior officials and C-suite executives who “gets results,” whether by direct engagement with state agencies, negotiating settlements and strategic transactions, or in court.
Trey Phillips is a partner in Marten’s Seattle office and a senior member of the firm’s Regulatory and Government Investigations practice, where he focuses on state AG matters, as well as environmental disaster response and strategic communications, real estate transactions, and agricultural and land use issues.
Trey hails from Louisiana where he served in a broad range of senior legal roles in state government, from a State of Louisiana litigation team member, to team supervisor in the Deepwater Horizon Gulf of Mexico oil spill in 2010, to Louisiana’s First Assistant Attorney General. During his six years as Louisiana’s First Assistant Attorney General, Trey also worked regularly with state Attorneys General, and their executive level staff, from across the nation on various issues of local, regional and national importance including litigation or commentary relating to EPA policy and regulations. In the Deepwater oil spill litigation, Trey selected, supervised, and worked together in the trenches with both in-house assistant attorneys general and outside counsel; partnered on a daily basis with high ranking members of the U.S. Department of Justice and other federal and state agencies, including the Office of the Louisiana Governor; and represented the Attorney General’s Office at the Louisiana Legislature, meeting regularly with the Senate President and Speaker of the House to secure the funding necessary to underwrite the expenses incurred in the Deepwater case. Additionally, Trey regularly testified before numerous committees of the Louisiana Legislature on a wide variety of issues including annual funding needs and outside contract counsel legislation for the Louisiana Department of Justice—a state agency with an annual budget of more than $70,000,000 and more than 500 employees, including approximately 200 attorneys.
Trey also previously owned family row crop agricultural operations in the Mississippi River Delta region of Northeast Louisiana and his practice encompasses a wide range of environmental, regulatory, commercial, technology, and trade issues facing agribusiness.
