Juan B. Sosa arrived in Washington, D.C. in October 1987 as Ambassador of Panama to the White House representing the Government of President Eric A. Delvalle. In February of 1988 he denounced Noriega's ousting of Delvalle and led a coalition of forces in the United States, in a fight to overthrow the dictatorial regime of Noriega. He continued to be recognized by the United States as the legitimate Ambassador of Panama and served until August 1989 upon termination of President Delvalle's constitutional mandate. An account of this turbulent period is documented in his book “In Defiance”. Ambassador Sosa has been in the private sector since 1963, having worked for Colgate Palmolive Company at the beginning of his career as an international marketing executive, and from 1969 to 1988 as Chairman of the Board of his own business and marketing consulting company. Between 1985 and 1987 he served as Chairman of the Board of Air Panama, the national airline, and between 1987 and 1989 as Member of the Board of Directors of the Panama Canal Commission. In 1994 Amb. Sosa, together with other prominent leaders, founded the U.S.-Panama Business Council, the business organization that took the initial step for a U.S.-Panama Free Trade Agreement. He served as its CEO until August 2014 when he became President Emeritus. In November 2014 Ambassador Sosa was appointed Consul General of Panama in Houston, Texas with responsibility over Texas, Oklahoma, New Mexico and Arkansas.

A graduate in Business Administration from the University of Oklahoma, Ambassador Sosa is married to Margaret de Sosa. The Sosas have fraternal twins, Enrique and Elisa, and reside in Houston, Texas.
