Hemel Hempstead manager Dean Brennan and assistant Stuart Maynard were presented with commemorative shirts by the Tudors Supporters Club on Saturday to mark their 300th game in charge.
The pair were appointed in 2012 and have had plenty of success with Hemel, winning 147 games, drawing 66 and losing 87.
Brennan and Maynard reached the landmark earlier this month with a draw at Bath City.
In their first season, the management team guided the club to fourth in the Evo-Stik Southern League, their highest ever finish. Hemel lost in the play-off final on penalties to Gosport Borough but bounced back the following season by winning the title.
The Tudors finished a highly respectable ninth in their debut National League South season and also reached the FA Cup first round where they lost at Bury.
In 2016, Hemel finished 6th, missing out on the play-offs by three points before coming 12th last season.
Under Brennan and Maynard, Hemel have scored 635 goals, conceding 446.
