Gary Gilchrist, who has been running the West London pub for three decades, decided to mark the occasion with two charity fundraisers for the Lily Foundation, which funds research into Mitochondrial disease - a group of disorders caused by dysfunctional mitochondria, the organelles that generate energy for the cell.
The day-long event saw a barbeque, face painting activities, a bouncy castle, a disco a magician, and a children’s karaoke.
Gilchrist said: “Both events went really well. It was great to see old and new faces there celebrating with me on my 30th anniversary at the pub.
“It was amazing to see how generous people were when donating. I can proudly say we managed to raise a staggering £10,000.
“I’d like to thank everyone who attended and also the Brook House staff – It’ll be a day I’ll never forget.”
In the evening, guests were treated to a complimentary glass of champagne on arrival and canapes with bands playing throughout the evening, topping off with a fireworks display in the pub's award-winning beer garden.
Enterprise regional manager Gavin Cook said: “We’re delighted that Gary and everyone who attended enjoyed the charity events.
“He’s done a tremendous job since joining the Brook House. The amount of loyal customers that keep coming back speaks volumes, so we have to congratulate him on that.
“The amount of money raised really is phenomenal. It’s for a fantastic cause so thank-you to everyone who donated.”
The Brook House have been involved with the chosen charity ever since employee, Tara Brown, lost her two year-old son, Dylan, due to a heart defect in May 2012.
