Andrew previously worked for eight years at Dairy Crest and before that at several major retailers at commercial director level.
At The Wensleydale Creamery, in Hawes, North Yorkshire, Andrew will be tasked with ensuring the company capitalises on opportunities for growth, as well as boosting consumer awareness of its products.
"Peter brings a depth of knowledge from his years working at a strategic level in a variety of retail, consumer and food sector businesses, which will help drive our development," said MD David Hartley.
Andrew added: "Working in a medium-sized business brings greater responsibility than working in a large corporation as any decisions have a more immediate effect. I am looking forward to being in a position where I can really make things happen."
