Originating from Co. Kildare, Ireland, having moved to the UK as an 18-year-old to study Sports Coaching Science at St. Mary’s University in Twickenham close to The Stoop, Mullen retired from a playing career that saw the Irishman represent Esher, London Scottish and London Welsh at the age of 23 due to injuries.
Mullen then moved onto Loughborough University to study a Masters degree in Sports Management. He progressed through the Loughborough Students’ coaching system, taking up the lead coaching position of the University’s development team in 2014 alongside his position as Head Coach at Lichfield RFC in National League 3 before going on to become the Head Coach of the Loughborough Student’s programme in 2017.
During his time leading the Students team, Mullen coached a host of regular Premiership names, including the likes of Saracens wing Rotimi Segun, Worcester Warriors hooker Issac Miller and Wasps lock Thibaud Flament, among others.
In August 2020, he was confirmed as Harlequins Women Head Coach ahead of 2020/21 Premier15s season.
