US food maker Ralcorp Holdings has appointed Terence Block as president and COO of its Post division.

Block will take up the position next January, following the completion of the separation of Post from Ralcorp.

Ralcorp said on Friday that Block would oversee the implementation of Post's strategic plan of growing its most important brands, improving innovation, extending its portfolio of brands into other categories and continuing to grow its presence among Hispanic consumers.

Block currently serves as president of Nestle Purina's North American pet food business. He has previously worked for Ralston Purina Company and Procter & Gamble.

"Terry's extensive operating and marketing experience will greatly benefit Post Holdings as we embark on an independent course for the company. I am confident that as COO, Terry will help drive the innovation, brand extension and growth initiatives that will be key to Post Holdings' future success," Ralcorp chairman William Stiritz, who is set to be CEO at Post, said.
