Guy Miller, founder of BioMatrix, became leader in feed additives

Dr. Guy Miller

PRINCETON – Guy W. Miller, who built a small Princeton business into an international leader in the feed additive industry, passed away after a long illness.
Miller was a microbiologist who earned his PhD in anaerobic microbiology from Kansas State University in Manhattan, Kansas. He founded Princeton-based Biomatrix International.
Guy Miller said in a 2015 interview with the Princeton Union-Eagle that he started the company in 1997 in an office he set up in his bedroom when he was living in the Twin Cities.
He moved the business to Princeton in 2002, locating it in a Baldwin Township industrial park along Sherburne County Road 45 just south of Princeton city limits.
He expanded the operation by having a new building constructed in Princeton’s main industrial park in 2007 and expanded that structure by about 10,000 square feet in 2014 and another 9,600-square-foot addition in 2015.
BioMatrix manufactures additives for livestock and companion animals, with 60 percent of the additives sold for livestock. The company also makes food additives for exotic animals. Today, BioMatrix ships to about 14 countries including the Philippines, Spain, Egypt, Mexico and Canada. Some of the largest feed companies in the world are BioMatrix customers.
“Guy (Miller) understands how different ingredients affect animals to create more healthy animals so they are more resistant to germs. The idea is to flood the system with good bacteria and put in carriers that the bad bacteria will attach to so they are carried out of the animal, said Biomatrix co-owner, chief operations officer and chief financial officer Mark Thompson in a 2013 interview with the Union-Eagle.
In 2015, it was a proud moment for Miller when the business he started from scratch was honored by being a recipient of Finance & Commerce Magazine’s “Progress Minnesota” award.
