Meet The Team

Scott Friesen - Chief Executive Officer

Well acquainted with Medford and the surrounding area, the Friesen family has a heritage steeped in Rogue Valley culture and history. As the son of Al and Deana Friesen, Scott was born and raised in the cradle of Southern Oregon. Upon completion of the South Central Oregon Sheet Metal JATC apprenticeship, and after working 8 years at a local sheet metal shop, he and Scott Rosendahl founded Advanced Air & Metal, Inc.

In 1988, Scott married Keri and together they have raised their two children into young adults. Scott enjoys cruising his Harley on the back roads of the northwest while listening to 80’s hair metal, scuba diving in tropical places, salmon fishing on the Rogue River, and backpacking into wilderness areas with his son. Scott is an avid football fan of the Oregon Ducks. Every spring, he and his family, and a large group of friends meet at Stewart State Park for campfire stories and fishing at Lost Creek Lake.

Scott is inspired to help others; whether devoting time to his family, designing complex air systems, or taking mission trips to Central America, he is motivated to serve others.
