Rosamaria Caballero

Just a few years after launching, Green Irene is already the largest green consulting firm in the country -- numbering 600 people in 48 states. Stafford and Caballero chose to focus on finding quality, passionate greenies who really take eco-living seriously. Now they are taking it a step further, introducing a line of green wares, including cleaning supplies, LED light bulbs and other products geared toward green-minded businesses.
