Dorgan first came to prominence with the Ballincollig minor hurling team that won the Premier 2 Championship title in 2012.[1] He subsequently joined the club's senior teams in both codes and experienced his greatest success in 2014 when the Ballincollig senior football team won the County Senior Championship title.[2] Two years later he was top scorer when the Ballincollig hurlers claimed the County Intermediate Championship.[3] By this stage, Dorgan had also made an impression on the inter-county scene as a Gaelic footballer. In spite of not being included on the Cork minor team, he was an unused substitute on the Cork under-21 team that lost the 2016 All-Ireland final to Mayo. Dorgan also lined out with the Cork senior football team on a number of occasions during the 2018 National League.[citation needed]
