Williams, whose Swansea City side are riding high in the Championship, is keen to encourage youngsters to follow a healthier lifestyle.
He has teamed up with his former Hednesford Town team-mate Tyrell Simpson to launch the school and has chosen his home town of Tamworth as his first venue.
Williams said: “I have been doing a lot of charity work in Swansea but was keen to come back to Tamworth and do something worthwhile.
“Tyrell and I, with the support of Belgrave High School, decided to run some soccer camps over Easter.
“With it being Belgrave, it’s like I’ve come full circle,” added Williams, who played for Belgrave Bullets as a youngster.
“We want kids to have fun in the sessions.
“It’s a chance for them to play all day in a safe environment, so parents don’t have to worry about their whereabouts.
“And they may learn a few things along the way because we will be giving out brochures that talk about the importance of eating healthily.
“What we want is for kids to interact with other youngsters and enjoy themselves.
“A lot of the time now, people can get preoccupied with Facebook or Call of Duty or television.
“So this is a chance for them to meet some new friends and burn off some energy.
“And who knows? There may be some future professional players in attendance.
“If you are dedicated and determined, there’s no reason why anyone can’t achieve their goals.
“I remember playing for Hednesford at places like Chippenham Town and waiting tables at the Beefeater in Tamworth.
“Back then, I never dreamed I would one day be playing against England and battling to win promotion to the Premier League.
“But if you apply yourself to something and are serious about it, whether it’s being a footballer, doctor or anything else, there’s nothing you can’t achieve.”
Williams will launch the camp which ‘teaches character through football’ at Belgrave High School, in Birds Bush Road, on Monday.
Youngsters are invited to attend and meet the Welsh star and enjoy a kick-about from 4pm-5.30pm.
Sessions, for boys and girls aged 8-14, will then take place between 10am-2.30pm from Tuesday-Thursday next week.
There will also be small-sided games and tournaments and those who take part will receive a gift and certificate.
The three-day course costs £30 and, for more information, call 07701 007708 or email email@example.com
