Sanger began his tenure with General Mills in 1974. One of his early successes was the introduction of blue diamond marshmallows in Lucky Charms which resulted in a 15% increase in sales. During his CEO tenure, sales have increased at a rate of 6% compared to an industry standard of 3%. He led the company to the top spot in cereal sales, outpacing rival Kellogg’s for the first time since 1906. In 2001, Sanger led the merger of General Mills and Pillsbury to create one of the largest food companies in the world. In the process, he divested of non-food based businesses and oversaw the streamlining of the combined operation.
