Nine-time Paralympic swimming champion Chris Holmes hopes this summer's Games will herald a shift in attitude towards disability sport in Britain.
Holmes has also promised the 14th Paralympic Games would be the "greatest ever" as organisers celebrated 100 days to go until the start of the event in London.
Some 4,200 athletes from 165 countries will take part - a significant increase on the field who competed at Beijing four years ago - and the event will receive widespread coverage on Channel 4.
Holmes, who is London 2012's Paralympic integration director, thinks the Paralympics could be the first to sell out in the history and hopes the public embrace and admire the athletes' dedication to their respective sports.
"If we get this right I really believe we can enable a fundamental shift in attitude towards, and opportunities for, disabled people," Holmes said.
"That's a phenomenal prize and one worth working hard for.
"We are focused 100% on staging the greatest Paralympic Games ever. I believe that when people witness Paralympic sport, when they see those world-class performances across the Games, they will have such a positive impact.
"That will enable more sporting opportunities for young people, particularly young disabled people."
One million tickets have been snapped up since they went on sale and London 2012 today made another million available.
London 2012 chairman Lord Coe thinks the Games will be a sell-out and Holmes thinks such a scenario will be crucial to boosting the event's credibility and acceptance.
"We have had a great response from the public so far," Holmes added.
"We want to make sure that we sell out all those venues.
"There will be phenomenal support. "You have seen that with the undertaking of tickets so far.
"The athletes need those stadia to be full of support to roar them home to medal success."
To boost sales organisers announced yesterday that multi-award winning British band Coldplay will play during the closing ceremony and on the last night of competition in the Olympic Park.
Blade Runner Oscar Pistorius, who won a silver medal competing against and alongside able-bodied athletes at last year's World Championships, will be a big crowd-puller, but there are a number of stars in the British team who are leaders in their respective disciplines.
Chief among them is swimmer Ellie Simmonds, who won two golds in Beijing at the age of 13.
Holmes, who won nine Paralympic golds in the pool over four Games, thinks the Briton has an excellent chance of adding more medals to her collection this summer.
He said: "Ellie Simmonds is a tremendous prospect for later this summer.
"She was a double Olympic gold medallist at the age of 13 and that is simply stunning. She is in great shape for these Games too."
