Richard Warren has spent his career working in and growing agencies, but most recently has worked in house at one of the UK's largest banking group, Lloyds. In 2000 Richard founded DLKW as Director of Strategy, which grew to become the the UK’s largest independent agency, before merging with Lowe in 2010. As someone who has spent time on both sides, I wanted to catch up with Richard to find out how to make the most of the agency-client relationship.
