David Kahl is the CEO and founder of Fully, a Portland-based office-furniture brand acquired by Knoll earlier this year, designing desks and chairs which, it says, encourage a more active and energetic workspace. Kahl started his professional life as an accountant. The job took him to Manhattan, where he lived through the horrors of September 11th, an experience that inspired him to focus on building positive work environments. He launched Fully in 2006, which is now a Certified B company working with top manufacturers in Europe.
