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.

Scott Rosendahl, Treasurer/Service Director

Scott Rosendahl was born in Southern California and relocated to Grants Pass in 1973. He enrolled in the United States Air Force in 1979, and, while stationed in the Philippines, began his technical training in heating, ventilation, and air conditioning. After 6 years of service, Scott returned to the Rogue Valley where he was employed as an HVAC service technician for more than a decade. In 1993, he married Ginny, with whom he has raised their son. In 1994, he and Scott Friesen founded Advanced Air & Metal, Inc. 

Scott is a sportsman and an outdoor enthusiast. He enjoys hiking and camping in the upper Rogue River wilderness. Scott is a patriot, fond of country music and Clive Cussler adventure novels. He has a great appreciation for the recreational opportunities that are uniquely characteristic of southern Oregon’s seasonal climate and geographic location. When he is not working, he can be found in the back country, riding his dirt bike, or fly fishing at the Oregon Coast.
