Based at the Seneca County Airport, Tiffin Aire Inc. was founded in 1968 by Dwight and Jeanne Gnepper. It began with only three employees, two single engine aircraft, two hangars, and an office. In 1989, after many years of growth and expansion, the Gneppers retired and sold Tiffin Aire to their daughter and son-in-law, Brad and Kim Newman.
