Over 100 years ago the Gibson Instrument company hired teacher-agents to sell, teach, and organize mandolin orchestras across the country. The teacher-agent model is no longer used today, with instruments available from vintage dealers, independent luthiers, and Gibson. But, the role of the teacher still exists in the form of those that organize mandolin orchestras for today.
Adam Sweet is one of those organizers. He would probably have been a highly sought after candidate as a teacher-agent for Gibson if he were born during that era.
