Greg Hyatt graduated as valedictorian from Central Catholic High School and holds degrees from Yale University and Boston College Law School. He began his career practicing law and transitioned into public service, where he played a significant role in shaping tax policy through Proposition 2½. Hyatt's career includes leadership roles in political campaigns and public policy initiatives, although he faced multiple legal challenges and disbarment. He has demonstrated a capacity for policy advocacy across various domains, including education, public safety, and criminal justice.

Greg Hyatt's political journey is marked by ideological fluidity and controversial policy stances. Initially a Republican, his advocacy for limiting property tax increases through Proposition 2½ contrasts with his later support for state aid to private schools. His opposition to mandatory seat belt laws and roadblocks for drunk driving reveals a libertarian streak in public safety issues. Despite his conservative roots, his switch to the Democratic party in 1992 suggests a strategic recalibration, though his consistent opposition to public funds for abortions maintains a traditional conservative stance.
