Our History

History of The Jamar Company

We Know What Counts.

We certainly have staying power — more than 100 years of it, if you’re counting. We are.

In fact, that’s one of the reasons we’ve grown from Walker Jamar Sr.’s initial $500 investment to a multimillion-dollar company.

We know what counts: helping you make every dollar of your investment count.

Interestingly enough, before making his investment, Walker found work counting hours – as a timekeeper with A.H. Krieger, a Duluth, MN, pipe-covering firm. Learning the business, honing his skills and, most importantly, counting his savings, he bought the company five years later.

In 1985, APi Group, a St. Paul-based private holding company, brought us into the fold. Acquisitions since, such as Arrowhead Refrigeration, further enhance our capabilities.

But through it all, we stayed true to our founder – making every hire, every estimate, every project, every conversation, every day – count.
