Meet the Team


Leadership Team

Brian Toll, Founder and President

With oil and energy prices on the rise and global warming all over the news, Brian went looking for ways to reduce his energy costs and environmental impact. Frustrated with his experience at big box retail and suffering from information overload thanks to the internet, Brian left his role in Sprint Nextel’s marketing department to found ecobeco, a company whose primary mission is to end the confusion of what it means to be eco-friendly and to make it easy for consumers to implement eco-friendly solutions in their homes. Over the years, as Brian learned about the linkage between housing and human health, ecobeco has evolved its focus to deliver best-in-class housing upgrades and remodeling solutions that are both eco-friendly and healthy.  Brian, his wife and son live in Bethesda.
