Seattle-based brand design firm Hornall Anderson announced that its United Kingdom partner agency, The Core, has become Hornall Anderson U.K. and will operate as its full-service European-base.

The Core was acquired in November 2010 by Hornall Anderson’s parent company, Omnicom Group Inc. (NYSE: OMC). This was a strategic move to build on the competencies of two well-established companies. Aligning the two offices accelerated their ability to serve a growing list of international clients and their global needs.

“This merger is truly the culmination of two firms that share a common philosophy, vision and commitment to deliver breakthrough ideas; ideas that create impactful experiences,” said Jack Anderson, Hornall Anderson’s CEO. “We believe the U.K. team brings agility and nimbleness that complements our existing rapid prototyping philosophy, while also providing a European sensibility and perspective that will help us continue to deliver exceptional, globally relevant work.”

In conjunction with the announcement, Hornall Anderson has designed a new Web site that reflects the company’s direction and global presence and showcases the culture, synergy and combined thought leadership of the two offices. To check it out, go to www.hornallanderson.com.
