The Team

Steve Dunfield 

Steve Dunfield - President

Steve began his career working in high technology in the Silicon Valley. After relocating to Oregon in 1991, he worked at Hewlett Packard in product engineering where he developed quality systems experience. He went on to business development roles at HP founding many life science business opportunities which led to him starting up biotech companies.

His passion for improving wellness through natural products and whole functional foods led him to Dr. Gary Stoner's work on black raspberries and freeze drying as a preservative free way to improve the distribution of high quality berry products. Providing convenient, year-round access to high quality black raspberries grown in Oregon by Sturm's Berry Farms enables our customers to increase consumption of this super berry.

Don Sturm - Expert Grower and Director of Farm Operations

Don Sturm is a 3rd generation berry farmer whose family has owned and run Sturm's Berry Farm for over 50 years. Don has worked to grow the best black raspberries in the world, and is constantly innovating with new ecological farming practices to produce better berries by working with nature instead of against it.

Don spent many years taking truckloads of his fresh berries all across the Northwest, and as far away as Utah and Arizona. People didn't always remember his name, but they certainly never forgot his delicious berries, and soon he became known simply as "The Berry Man," a name that now can be found on the side of his trucks.

Don's incredible knowledge of black raspberries and farming techniques helps us grow consistently amazing black raspberries each and every harvest.
