Southwell was the director of strategy and group board director of Berkeley Communications.
He spent six years at Berkley and has previously worked as an account director at Red Consultancy, as well as stints at Band & Brown Communications and University of Leicester.
He has worked with clients including BMW’s Alphabet brand, Disney, Epson, Freesat, Siemens Healthineers, Staples Solutions, Yodel and Zyxel.
At McCann Central, which has 70 staff in Bristol covering McCann’s full range of marcoms services, Southwell will be responsible for clients including Cathay Pacific, FlyBe, Haynes Manuals and Bottle Green, among others.
"Pat joins an incredibly strong senior management team and will supercharge our PR and social activity, making the 70-strong staff in Bristol a force to be reckoned with. We’re continuing to win work with some of the UK’s biggest brands and his creativity and knowledge of the sector can only help to strengthen that position," said Andy Reid, managing director of McCann Bristol.
McCann Central’s PR and social operation is now one of the largest regional operators, with a team of 60 across offices in Birmingham, Bristol, Milton Keynes and London, providing a range of specialist services across PR, social and influencer.
Southwell said: "Joining McCann couldn’t be a better move. It’s a global powerhouse that I’ve always admired. Being part of the team is a huge honour and I can’t wait to grow the PR and social team even further. We’ve got some fantastic clients and soon there’ll be even more."
