I've had the good fortune and privilege to meet many famous people in this job.
Royals, Prime Ministers and household names from the world of entertainment, business and sport.
Its always an honour, but inevitably, as time has gone on I have become less excited and awestruck by it all.
But that will all change next Tuesday.
Julie Walters.
Need I say more?
Except, 'award-winning', 'multi- talented' and 'one of Britain’s best-loved actresses'.
Julie Walters is kindly supporting us at our charity event in London on 31st August.
The special 'Audience with Julie Walters' evening is to further raise our profile in the capital with established and potential supporters.
BBC Radio 4's Jenni Murray - a former patient, supporter and also good friend - will be there to lead the questions and chat to Julie.
With 26% of our patients coming from outside Greater Manchester and Cheshire and our research helping to save lives across the UK and beyond, its important to promote our charity on a national level.
It'll be great to have the opportunity to chat to all our special guests at the event.
And I won't worry about any 'awestruck' moments.
Julie Walters! Need I say more ?
