Our Story

    After working in the industry for several years, Brian Golie identified a gap in the market for a supplier that could provide consistent and high-quality raw materials for in-vitro diagnostic manufacturers. In 1989 Brian Golie started Golden West Biologicals, Inc (GWBI) to fill this gap by being a supplier dedicated to understanding and servicing the needs of the biological industry, while sourcing excellent manufacturers to acquire products that provided quality, consistency and value.

    GWBI carried on its quest for high quality and consistent products by opening its first manufacturing facility in 2004, while continuing to distribute biological products. Both divisions continued to grow, with much gratitude and appreciation to our loyal customers. In 2015 GWBI provided three solutions by transferring its manufacturing division to its subsidiary Golden West Diagnostics (GWD) and transferring its distributed products to Golden West Biosolutions (GWS) and maintaining its distribution of therapeutic Human Serum Albumin for excipient use under GWBI.
