Mary Vermeer Andringa was born in Oskaloosa, Iowa and raised in Pella. She received a degree in Music Education from Calvin College of Grand Rapids, MI in 1971, and worked as a teacher and pre-school director in her early career. She joined the Board of Directors of her family's business, then known as Vermeer Manufacturing, in 1976, and joined the company as a market researcher in 1982. She was named President and COO in 1989, later named Co-CEO with her brother Robert Vermeer in 2003, and sole CEO in 2009.

With the family's leadership and a dedicated team, Vermeer Corporation has evolved to become the type of company upon which others model their programs and initiatives. Andringa was instrumental in launching the company's Continuous Improvement ("Lean") program in the late 1990's, driving the company and its employees to consistently achieve more with fewer resources. She also led the creation of Vermeer University, an area devoted to employee and equipment dealer development. She has led the company through the development of many other significant initiatives emphasizing safety, professional development, and efficiency.

In addition to her responsibilities at Vermeer, Andringa is also active on the Boards of Directors of other organizations and in community activities. She is a Trustee Emeritus of Central College in Pella, Director of the Herman Miller Company, incoming Chair of the National Association of Manufacturing, Past Chair of the Iowa Association of Business and Industry and Past Chair of the Governor's Task Force on Rural Health, among many others. In 2010, she was named to the President's Export Council by President Barack Obama.
