John Costello is to retire as chief executive of Dublin GAA later this year after almost three decades in the role.
Costello was appointed in 1994 and is credited with implementing structures that culminated in the most successful decade in the county’s history as they won eight All-Ireland senior football titles between 2011 and ‘20 having established a stranglehold on the Leinster Championship long before that.
In addition, Dublin hurling has enjoyed a resurgence during his tenure with the team winning League and Leinster titles in 2011 and ‘13 respectively after going decades without any success of note, albeit they have regressed somewhat in the meantime.
