The TriState Thoracic Society, formerly known as the Pembine conference, is a spirited annual meeting of pulmonologists and thoracic surgeons from Minnesota, Wisconsin, and Michigan. This clinical conference will again be held in scenic Door County, Wisconsin, where pleasant weather and recreational opportunities abound. In the tradition of the conference, case based presentations and discussion of practical clinical problems will be presented and discussed in an open format. This fun and light clinical conference is one of the longest continuous medical conferences in the United States. It is steeped in tradition with a spirit of enjoyment, practical learning, and camaraderie.
