The Petersens are a popular bluegrass band located in Branson, Missouri. The group was founded by Jon Petersen (a retired air force colonel and doctor) and his wife, Karen with the idea of having the family doing something together. The band's current working lineup features Karen Petersen, four of her children, and Emmett Franz, a non-family member who joined the band in 2017 to play dobro. When the band started Karen played the mandolin, and Jon Petersen played stand-up bass or piano. However, Jon Petersen rarely plays with band, anymore. He continues to work his day job as a doctor.
