Born in Michigan, Peter received his undergraduate at UNC Chapel Hill followed by a law degree at Temple University in Philadelphia, before moving to Miami in the early 1980s. Upon arriving there, he first interned at Dade County Public Defender but left to work at American Friends Service Committee as staff attorney representing imprisoned undocumented people at Krome Detention Center. There he also represented undocumented farmworkers in rural areas throughout south Florida, including Indiantown in western Martin County. While representing some West Indian clients on immigration proceedings after they jumped their contracts with Big Sugar, he found a healthy outrage for the sugar industry, its practices and its post-colonial exploits. In '88, Peter moved to NYC then to Mozambique to work for Save the Children where he assisted with war traumatized children. From New York, he came to Indiantown to open a private immigration law practice. He eventually settled his family down in Stuart where he became a member of several boards including Americans for Immigrant Justice in Miami and the Elliott Museum where he was board chair from 2014 through 2015.
