Brill originally joined the Club as a goalkeeping coach in 2017, following an injury hit end to his time in Scotland.
Under Justin Edinburgh, however, Brill came out of retirement and became a vital member of the squad, with promotion set in The O’s sight.
In the 2018/19 season, he kept 23 clean sheets in all competitions, as Orient returned to League Two.
After sustaining an injury, Brill reprised a role in the coaching staff, before taking up the role of Goalkeeping Coach again at the start of the 2020/21 season.
Director of Football Martin Ling praised Brill’s hard work during his time at The O’s:
“I’d like to thank Dean for the four years he has committed to this football club, both as a player and a coach. He was excellent in both roles.”
Ling continued, “I was disappointed when Dean first told me because I don’t like to lose good staff, but it shows the quality of staff we are producing at Leyton Orient Football Club when clubs like Tottenham come calling.”
A message from Dean
“I wanted to say thank you to the Club; when I came in as part of the rebuild, I was lucky enough to be given my first coaching role, and a job of that magnitude was brilliant, and has set me up to where I am today,” said Brill.
“Things transpired, and I ended up playing, which gave me a fairy-tale ending to my career, having had a bad injury in Scotland. I played over 100 games for the Club and had some unbelievable times in helping the club get it back to where it needed to be.”
“The memories of promotion, that season, the group of people, the fans. It was just a special time. Losing Justin was massive, but as a Club we all rallied together, and he’ll always hold a massive place in our hearts.”
“It’s been a crazy four years, and to finish back where I started, and to get the experience to go on to try my hand at something else, which is developing young goalies, something I’m really passionate about.”
“We’ve just had Rhys [Byrne] come through on the back of a bad injury, and I’ve absolutely loved working with him. It’s so special to see these young players develop, and to pass on your experiences to help them grow.
“I’ll be forever thankful to Orient – it’s a shame we didn’t get to experience full stadiums this year, but I’ll be back to come and see everybody – and hopefully we’ll all be smiling as Orient kick on.
The Club would like to thank Dean for everything he has done for Leyton Orient and wish him success in his new role.
