Trendwest was created in March 1989 by Jeld-Wen Inc., a privately held window and door manufacturing company based in Klamath Falls, Oregon. WorldMark, The Club was incorporated July 18, 1989 [originally "Club Esprit"; renamed as "WorldMark, The Club" by Certificate of Restated Articles of Incorporation of Club Esprit, Dec. 11, 1992]. Trendwest began selling WorldMark vacation credits in October 1989. WorldMark was created hand-in-hand with Trendwest Resorts. Trendwest was the Developer and the Manager, and WorldMark was the owner. They were created together to support one another. As the WorldMark's Board of Directors has frequently stated, the two were inter-dependent; neither could survive without the other. And that was fine; it really was a case of "what is good for one is good for the other".
