Fred Keller

Born and raised in Billings, Montana. Graduated from Billings West High in 1981, attended Eastern Montana College (MSUB). In August of 1984, I married my wife of 34 plus years and we have been blessed with 4 children. I have worked in many capacities as either the manager or owner of a business, from retail work in high school to managing a motion picture theatre and even serving as City Manager in Billings, MT, Dickinson, ND, Mankato MN, and Missoula MT. After that, I became involved in the restaurant and casino industry. From there, I owned and operated a large screen printing company until returning to Billings in 2002. That is when I began my career in the housing industry, where I pursued my love for building. I have held several different positions in the industry, including operations, construction, delivery, sales and management. My greatest joy in working in the industry comes from being able to help families realize the dream of home ownership and possessing the knowledge and skills to help them make that happen.
