Having worked both for and with local advertising agencies I’ve got to know quite a lot of graphic designers and web designers in Brighton.
My pick of the bunch of graphic designers would be Harrison. Run by Chris Harrison, Harrison are experts in creating brands and visual identity. Their clients include Brighton Festival, VisitBrighton and Barclaycard.
In terms of web designers I would recommend Republique Design. Run by Simon Cooke and Richard Copping, Republique are an innovative team of web designers who are always keen to stay ahead of the competition. Their clients include Virgin Holidays and Bang & Olufsen.
