Angus started his working life in 1969 as an attorney for Pine Tree Legal Assistance in Skowhegan.

From there, he shifted his focus to causes that would better the lives of people in Maine – from working as chief counsel to the U.S. Senate Subcommittee on Alcoholism and Narcotics in the office of former Maine Senator William Hathaway to joining an alternative energy company and then founding a business committed to energy conservation initiatives.

In May of 1993, motivated by his concern about the Maine economy and the negative effects of excessive partisanship, Angus declared his intention to run for Governor of Maine as an Independent. Eighteen months later, he won the election, beginning two terms that he dedicated to creating jobs, reigniting the economy, reforming the state’s mental health services, investing in the public education system, working toward common-sense environmental regulations and more.
