Business Operations Director, PHD UK

Graham Cox

After 6 years cutting my teeth in Display/Programmatic/Print for large automotive brands (Ford, VW Group), an opportunity arose to make a full-time job out of my side-passion for finding efficiency and improving processes by moving into the fledgling Business Operations team at PHD. In the 3 years since, I have evolved the team from finding its feet to being an integral part of the agency which most other teams rely on to some extent.

Most shopped item: A few years ago I had the pleasure of being ranked #2 buyer of Sunbites Sweet Chilli crisps at my Sainsbury’s Local in Stockwell on my Nectar yearly review, which I was pretty proud of! I get most of my main meals via a recipe box service, so these days it’s probably something boring like milk or bread I buy most in Sainsbury’s. But having recently moved to a new house, my girlfriend gets very excited when we go to a mega Sainsbury’s that has a big Habitat section and she can buy stuff “for the house”!
