Garry Kimble arrived on loan from Charlton Athletic with his twin brother Alan and played twice for Exeter City in September 1985. He later appeared for Cambridge United, Doncaster Rovers, Fulham, Gillingham and Peterborough United in a near 200-game Football League career. The highlight of his brief stay at St James' Park was scoring in the League Cup against Plymouth Argyle. 

Garry started his career at Charlton Athletic alongside his twin brother Alan. They each progressed through the youth ranks to make brief appearances in the Charlton first team before they both joined Exeter City on loan in August 1985. Like his brother, Garry played for the Grecians in the 2-0 home League Cup victory over Plymouth Argyle (when he scored the first goal) and the 0-2 defeat against Southend United.

Joining Cambridge United on a free transfer in August 1986, Garry made 41 league appearances (scoring twice) before moving to Doncaster Rovers for a fee of £7,500 in October 1987 where netted once in 65 league matches. A two-month stay at Fulham followed in August 1989 ahead of spells with Maidstone United and St Albans City. Returning to the Football League with Gillingham in February 1990, he added a further 48 league appearances prior to a July 1991 switch to Peterborough United where he added four goals in 30 league starts in a single-season stay. 

After leaving London Road, Garry played for Dagenham & Redbridge, Sittingbourne, Purfleet, Grays Athletic, Chelmsford City, Canvey Island, Aveley, Braintree Town, Harlow Town and Maidstone United. He subsequently managed Burnham Ramblers before becoming assistant-manager to brother Alan at Aveley in May 2010. 

Remaining in non-league management in the Essex area, Garry had later stints with Witham Town (where he won promotion twice) and Great Wakering Rovers before a return to Witham in 2023.
