Bill Bean


My interest is in business planning and coaching in the “green” space. That involves consulting and teaching to help people capture the vision for their “green” initiatives and build better business plans faster to achieve them. I have taught business workshops and done consulting for years and in 2009 structured a program to fit the university format which was offered in the winter session in a course entitled, “Building a Formalized Business Plan For Your Green Positioning”.

My academic background includes a BA and a Masters in Wood technology from UMass, Amherst in the mid 70’s. That led me to a position with International Paper Company in Manhattan in strategic planning for their Wood Products Group. Since that time I have had over 30 years in the field, in sales, sales management and consulting in the US and Canada, developing business plans and building and managing the teams to execute them.

A few years ago I did a planning and coaching engagement for a company in Florida with a “green” event center and it seemed that everyone in business who was having fun at that time was somehow associated with “green” and sustainability. That was the catalyst to me pursuing my LEED AP and NAHB CGP designations, combining them with professional certifications in Executive Coaching, Career Coaching and Retirement Career Coaching and launching a small consulting business called Green Planning & Coaching.

I would be happy to answer any questions about the course offering and feel free to visit my website to learn more about the business and my background.

John Fabel

Mr. Fabel is widely recognized both for his pioneering work in sustainable technology innovation and commercialization, and for his work as an educator in entrepreneurship and innovation. Much of his work focuses on how we ultimately develop meaningful markets for sustainable resource production and low-carbon products and manufacturing.

As an inventor and designer, he holds or is named on numerous patents ranging from structural engineering to microbial genomics. Mr. Fabel’s work is held in the collection of several museums, including the Smithsonian. He was a featured inventor in the Smithsonian’s “Invention at Play” exhibit that ran for a decade at the National Museum of American History. He was featured in author Daniel Pink’s “A Whole New Mind”, on the new wave of innovators driving change. He is also a featured inventor in the new “Invention” Merit Badge publication of the Boy Scouts of America. Mr. Fabel and his work have been widely featured in the media, including the Discovery, NPR, The New York Times, Popular Science, and so on. Mr. Fabel has designed and contributed to the development of many products. Among other awards, he is a 2-time recipient of Backpacker Magazine’s “Editor’s Choice” award for “gear of the year”. His book “Designing the Future to Honor the Past” received a merit award from the American Planning Association.

Throughout his career Mr. Fabel has bridged commercial and academic sectors. Within the academic sector, Mr. Fabel has worked extensively to develop and deliver innovative pedagogy for innovation and entrepreneurship education. Mr. Fabel taught for 4 years at Hampshire College, where he was a visiting Lemelson professor; for 3 years at the Isenberg School of Management at UMass/Amherst, where he developed and taught what is now the capstone course in technology commercialization and management; and for three years at the Marlboro College “MBA in Managing for Sustainability” where he was recruited to develop the entrepreneurship component of the program. Mr. Fabel was also part of the first IGERT grant received by the University of Massachusetts, serving as an entrepreneurial mentor to IGERT nano-materials students in Polymer Science. Mr. Fabel has extensive experience in grant making and strategic program development.

As a serial clean-tech entrepreneur, Mr. Fabel has founded several clean-tech companies and has been involved in the development and mentoring of many others. These include the ecotrek company, which pioneered the comprehensive use of recycled polymers and “cradle-to-cradle” design in outdoor products (and was an early effort to develop high-value markets for sustainable materials), and Sunethanol (now Qteros) a sustainable biofuels company he co-founded with UMass/Amherst microbiologist Dr. Susan Leschine. Recent work includes founding the bicycle and materials development company Sylvan Cycles, which makes bicycles and other products from novel high-performance bio-composite materials. Sylvan is using bicycles as an R&D platform for scalable high-performance structural materials based on low-carbon footprint manufacturing processes. These include commercial applications such as wind turbine blades and timber structures.
