Founders Jane and Dave "Doc" Barz

After graduation from Iowa State's Veterinary School in the spring of '74, an energetic naive Iowa farm boy brought his new bride (Jane) to practice veterinary medicine in Mitchell, South Dakota. In 1977 we moved to a Tripp, SD farm to raise our children in a rural atmosphere. Later a clinic was established in Parkston, SD with haul-in facilities and Northwest Veterinary Supply began.

Forty+ years later, I still enjoy my practice, the area, my clients and especially my grandchildren. I prefer to work with large animals in a rural family farm situation.
