GALLAGHER, DENNIS, 74, resident of South Fla. since 1967, lost his valiant battle with cancer on October 4, 2011. Born on Long Island in 1937 to Carolyn Keeneth Gallagher and Frank Gallagher, Dennis attended Sea Cliff schools and spent 4 years with the US Coast Guard, culminating in 2 exciting years in the Greek Islands as a radio man for the Voice of America. He moved the World's Fair hydrofoil operation to Miami in 1967, operating out of the Seaquarium and DuPont Plaza, working later as a yacht captain and at other marine industry positions. Dennis was pre- deceased by his parents and his sister, Patricia Lewis and is survived by his wife of 48 years, Caroljean; son, Sean; daughters, Jocelyn Thomas (David) and Erin Zangari (Marc); grandchildren, Ryan, Cameron, Max, Major and Riley and brothers-in-law, James Stephan and Thomas Stephan. After his strong devotion to family, his next passion was choral music. Dennis sang for over 30 years in several Catholic choirs, traveling to Rome, the Vatican and St. Thomas, VI for concerts. His happy, positive and loving nature will be sorely missed by his family and a host of friends, many dating from early childhood. A Mass will be celebrated at Holy Rosary - St. Richard Catholic Church, 7500 SW 152 St., Palmetto Bay, on Saturday, Oct. 15th at 11:00 AM.
