Julian Tagg was the fourth chair of Exeter City in the era of supporter/community ownership and served between 2014 and 2020. Associated with the club since his days as a youth player in the 1970s, the Exeter-born former college lecturer had been a youth coach, vice-chair of the supporters’ trust, chair of the community trust and club chief executive prior to his elevation to the club chair. 

When still at Ladysmith School in 1971, the 15-year-old Julian Tagg played his first match for City's reserves at Chard Town in the Western League. Later attending Exeter College, he was selected for the Devon Schools under-18 side in 1973/74 whilst continuing to occasionally play for City's various sides for another season or two. Subsequently studying to become a teacher, he attended St Luke's College shortly before it was subsumed into Exeter University and continued to appear in local football before a brief return to the ranks of Exeter City 'A' in 1983.

Going on to work as a physical education lecturer at Exeter College for over twenty years, he started gaining coaching qualifications from the age of nineteen and was still relatively young when he assisted in the management of some of Exeter City's teams. Much later, towards the end of the 1990s, he was invited to run City's first-ever under-12s by which time he was also in the business of organising educational summer camps. 

Keeping his links with Exeter City, he lent practical support to Eamonn Dolan's efforts to develop an academy and just as significantly, as the club lurched from crisis-to-crisis in the early 2000s, became an enthusiast for supporter-ownership as he duly took on the role of vice-chair when the Exeter City Supporters' Trust took control of the club in 2003. Performing a variety of roles with the supporters' trust and the City Community Trust, Julian eventually became chief executive and then chairman of the club when Edward  Chorlton resigned in 2014.

After a slightly uncertain three or four years, City's fortunes took a turn for the better on Julian's watch with top-five finishes in League Two in 2017, 2018 and 2019 together with a memorable home FA Cup tie against Liverpool along the way. Unfortunately, all three Wembley play-off finals ended in defeat although promotion was eventually achieved two years after Julian's six-year spell in the chair.

Nonetheless there were notable achievements in 2018 when Paul Tisdale, after twelve years as manager, was successfully replaced by Matt Taylor around the time the new Adam Stansfield stand - on the railway side of the ground - was opened and quickly followed by a revamped away end.

Remaining on the scene after stepping down as chairman in 2020, Julian became City's director of external affairs and club president alongside serving on the board of the English Football League. He was also awarded the British Empire Medal in 2020, for his work with the community aspects of football, and continued to advocate for the successful development of girls' and womens' football at Exeter City.
