David Green's philosophy of development emphasizes “deconstructing reality” to see that much of the world's problems are due to human artifice that creates economic paradigms favouring the concentration of wealth into the hands of the few. He addresses the pricing disparity that exists and works to put basic human needs like sight and hearing into the realm of affordability for the blind, visually disabled and hard-of-hearing. David has a Master’s in Public Health and Bachelor's in General Studies (Honours) from the University of Michigan. He is a MacArthur Fellow and Ashoka Fellow. David is the 2009 recipient of the Spirit of Helen Keller Award, given by the Helen Keller International for humanitarian efforts in blindness prevention, and the 2009 University of Michigan Humanitarian Service Award.
