Turner has over 25 years' experience in the meat industry and has been promoted from the role of commercial director, where he was personally responsible for the company's largest accounts.
In his new position, he will lead a team to strengthen existing customer relationships and add new accounts to the company portfolio.
2 Sisters CEO Ranjit Singh said: "Dominic has been an integral part of the 2 Sisters family for over 27 years, and his new position was an obvious, natural progression. The red meat business is the perfect tenure for him, and I'm confident that his entrepreneurial drive will only serve to strengthen this important area of our business."
Turner will officially be based in Cornwall, but expects to travel around the country visiting customers.
He said: "I believe in putting our customers at the heart of everything we do. Our whole reason for existing as a business is to serve customers with excellent-quality products on time, in full, every day. In such a large, complex business with so many 'moving parts', it's often easy to forget that our mission is simple: to delight our customers."
