The 49-year-old managed to keep the Tigers in England's top-flight, despite losing to Manchester United on the final day of the season...
The Tigers lost 1-0 at home to Manchester United on Sunday but beat relegation from England's top flight after Newcastle United lost by the same scoreline away at Aston Villa.
"It's the biggest thing I've ever done in my footballing career," Brown told Sky Sports.
"Getting promotion was fantastic last year but staying in The Premier League is absolutely brilliant."
Asked whether he kept up-to-date with the day's other scores, he replied, "The club captain and Jimmy Bullard were both on their phones, telling me the scores, and it was nerve-racking towards the end but fully deserved."
It had been suggested, before the game, that Hull would have an easy time at the KC Stadium with United resting a host of players ahead of Wednesday's Champions League final.
However, it proved to be anything but easy for the Tigers and Brown stated that he never thought it would be.
"Going a goal behind to a wonder strike from outside the box, we played well in the first half. But it's one of those, where you go a goal down and are climbing a mountain," he explained.
"No-one can question the Manchester United quality, it's there for everyone to see."
