2017 40 Under 40 Yearbook: Tammy Mast, 46

Then: Executive director, GYN Cancers Alliance
Now: President and CEO, Nixa Area Chamber of Commerce

Tammy Mast still has a heart for people. In 2007, she was the executive director of GYN Cancers Alliance and from there worked at several other organizations in the service of people. Prior to her current position as president and CEO of the Nixa Area Chamber of Commerce, Mast worked for Children’s Smile Center, which provides dental care for children and pregnant women who rely on Medicaid. There, she worked with several area chambers, which opened the door to her current position.

“I love having the opportunity to help other people no matter what it might be,” Mast says. “The chamber gives me the opportunity to help the whole community.”
