this article is somewhat dated, Harry Huff of Huff's Garden Mums and Vincent Dooley from MN have probably not been active for 10 years or more. Mums of Minnesota (
https://www.fgimn.com) carries some of Dooley's introductions. Company name is Faribault Growers.
G.H. Wild seems to carry about a half dozen mums from Mums of Minnesota, clearly the stock photos are from Faribault...

the Yoder Brothers (the largest producer of chrysanthemums in the U.S.) seem to sell most of the "florist" type chrysanthemums (not hardy). They are a wholesale company. I assume that the majority of their products are sold at the fall mum sales at your local nursery or grocery store.
As far as the National Chrysanthemum Society goes, I think "show" chrysanthemums refer to the fancy "greenhouse" mums, not to something you would grow in your garden.
