 He was Minister of Defense of the Dominican Republic from 1986 to 1988 (period in which he held the rank of "Lieutenant General" as incumbent of Defense); earlier that decade, his second-cousin Mario Imbert McGregor was also Minister of Defense.In 1989 he was assigned chairman of the board of directors of Rosario Dominicana.In September 2013, the "Constitutionalist Soldiers of 25 April 1965 Foundation" asked the National Congress of the Dominican Republic to explore the possibility of stripping Imbert his status of national hero as it considered that he went against constitutional precepts when he supported the coup against Bosch and the U.S. occupation of the country, among other accusations.
