Coleman came to Britain from
Cork in 1959 and started working in offices at Millwall Dock for the flour millers
McDougalls. He was appointed as a contracted trainer to
Romford Greyhound Stadium in 1968 and established a strong kennel of greyhounds and owners. His first big race success was Ace of Trumps who won the 1969
Scurry Gold Cup. He remained at Wembley until 1989 before taking a position at the leading track
Walthamstow. During the same year he finished runner-up in the
1989 English Greyhound Derby. Further final appearances came in
1993,
1996 and
1998 and in between he was Champion Trainer for the second time in 1995, a year that also saw him secure the
Trainers Championship for the second successive year. In 2008, Walthamstow closed and three years later in 2011, Coleman retired. He was based for most of his career at the Claverhambury Kennels in
Waltham Abbey. The one trophy that eluded him was the
English Greyhound Derby. ==Awards==
