The charity was established to provide help and support to those suffering with alcohol or drug addictions and a grand ball will be held at the Royal Yacht Hotel in March.
George Best, a former Manchester United and Northern Ireland footballer who is widely regarded as one of the game’s greatest players, famously battled with alcohol throughout his life.
He died in 2005 from complications following a liver transplant.
Calum, who has also had issues with alcohol in the past, will talk about his father’s struggles with drinking and the impact that alcoholism can have on families.
The organisation’s chief executive Jason Wyse said: ‘We have invited Calum Best to come along
and speak at our ball, which will be attended by corporates and individuals.
‘He will talk about having probably the most famous alcoholic parent there has been, and the struggles he faced.
‘It is nice to do something to celebrate Silkworth being here 25 years, and having touched thousands of people’s lives.’
The ball comes two years after Silkworth’s last charity event.
The Silkworth Challenge, which Mr Wyse said raised between £10,000 and£15,000 every year, was stopped because of a ‘saturated market of sporting charity events’.
Mr Wyse has plans to bring something back in the future, but wants to find something that is new and different.
He added: ‘It was a saturated market and people couldn’t commit because there were a lot of events, and we decided against it because we had to invest in the event.
‘It is a gap but we have managed to plug that gap.
‘I want to bring something back but it is about finding something different in its place, because an annual fundraiser makes a massive difference.
‘We have had donations from generous people who know what we do and have helped to fund specific projects and been a big benefit to the charity.’
