Brian Giesen

Head of Social & Content ANZ at Sling & Stone

Sydney, New South Wales

I love being at the forefront of digital and social media marketing. I'm currently director of social at Atomic 212 in Sydney where I'm focused on delivering integrated, data-driven social programs for clients.

Prior to this, I spent two-years gaining in-house social media experience in contract roles and 16 awesome years at Ogilvy, gaining deep, hands-on experience in digital and social media marketing both in the United States and in Australia.

In 2009, I moved to Ogilvy Australia to grow one of the first social media agencies here – going from one person to an award-winning team of 15 people who delivered successful campaigns for some of the world’s most-recognised brands.

During my time at Ogilvy in Washington, I developed and ran the agency’s first search marketing offering, created a website assessment product and was a founding member of Ogilvy’s global social media practice – helping to develop IP and training internal staff in North America.

Specialties: social media marketing and communications, content and copywriting, digital crisis management, training and workshop facilitation, influencer marketing, search engine marketing, website assessments, employee advocacy.
