Jason grew up in Minnesota City, Minnesota and moved to the La Crosse, Wisconsin area after graduating from Winona Senior High School in 1994. He married his wife, Gayle, in 2001 and they have two children, Abram and Oliver. You'll find the Lassen family in a hockey rink most weekends during the winter and down at Riverside Park during the rest of the year.

Jason originally earned his insurance licenses back in 2001. His career began in the mortgage industry and transitioned into insurance in 2010. Prior to becoming an Agent with American Family Insurance, Jason owned a wholesale mortgage bank, retail mortgage operation and a title insurance company. While the mortgage industry provided plenty of challenges that Jason enjoyed taking on, he found it to be too 'transactional'. The insurance industry provided him with a 'relational' opportunity to interact with his clients which he truly enjoys.

Jason looks forward to spending time with his wife, Gayle, and sons, Abram and Oliver. They are avid UW Badger hockey fans and enjoy playing hockey, football, baseball and soccer.

Jason won Shark Tank when he presented his agency business plan to Barbara Corcoran and Daymond John in front of an audience of 1,500+ American Family attendees.
