Brad Riddoch joins Ammirati Puris Lintas on Oct. 1 as executive vice-president, co-creative director, a title he will share with his new partner, Doug Robinson.

Riddoch, a copywriter, comes from Bates Canada, where he has been executive vice-president, creative director for the past two years.

Before joining Bates, he spent two and half years with MacLaren:Lintas (now MacLaren McCann) and nearly 10 years with J. Walter Thompson. His tenure at jwt was punctuated with an 18-month job at Creative Interchange.

At Bates, Riddoch is being replaced by Egon Springer, a former creative director at Saatchi & Saatchi, who has been with the Toronto agency for the past four years.

Margo Northcote, for seven years Bates’ vice-president, associate creative director, has been promoted to senior vice-president, creative director, and will be working closely with Springer.
