Keith Kelly

Assistant Coach

Keith has been coaching for many years within the county. He started at Trident where he assisted the head coaches in moving the club forward to become a force, not only within the local area but regionally – and then nationally as the programme developed.


His input with the squad members was instrumental in the success of a generation of swimmers from Long Eaton who moved on to National honours. He was part of the coaching team at Long Eaton SC that formed from the merger of Trident & Treonte Swimming clubs in the town.


He then moved in early 2007 to Derventio and has had similar impact whilst coaching at the Derby based squad.


His vision along with his work ethic has helped to empower swimmers within the team to keep making forward strides. Keith has now worked with a total of six swimmers who have made British Swimming Programmes and teams in recent years.
