Fromagex is the Canadian company and ServiDoryl the French one. I think the US one is called ServiDoryl USA. Fromagex and ServiDoryl do each have a separate catalog, and US orders do come from Chicago if there's inventory. Good place to get hardware, but they don't have cultures or ingredients.
The US operation is not very big. It used to be just one employee last year, Anne Stevens, doing everything.
