Aldo Santorum (1923–2011) was an Italian immigrant who moved to the United States as a child. He served as a veteran in World War II, which influenced his later career in veterans' affairs. After the war, he became a clinical psychologist specializing in mental health services for veterans, working for the Veterans Administration (now the Department of Veterans Affairs). His career spanned several decades, primarily in facilities in New Jersey and the northeastern United States, where he contributed to the region's veteran support systems. Santorum is best known as the father of former U.S. Senator Rick Santorum, to whom he imparted strong conservative values, discipline, patriotism, and a commitment to public service, significantly influencing his son's political upbringing. His personal experiences as an immigrant and soldier shaped his worldview, emphasizing resilience and public service.
