Bob Warner
Vice President
​
“Service” has always been Bob’s path. Attaining his pilot’s license while still in high school was a major life-change, which set the course of his entire career.
For 37 years, Bob served in national and international aviation associations, attaining senior positions at the Experimental Aircraft Association, National Association of State Aviation Officials and Aircraft Owners and Pilots Association. This career provided opportunities of management responsibilities spanning the gamut of non-profit organization planning and operations, utilizing his aviation management degree from Auburn University, considerable professional education coursework and his continuous flying experiences. He has led international delegations, flown in all 50 states and six foreign countries. He has owned 7 airplanes and, with his wife, Noel, completed initial development of a residential airpark.
But in 2008, life really took a turn. That year, Bob stepped away from the career-driven life and began embracing a more purpose-driven life. Decades of accumulated “stuff” went to charities (including Casa Esther) and the dump. A discovery of true life-purpose and simpler living emerged through spiritual growth and study.
By 2010, he and Noel have traded in their flying airplanes for a journey down the Consciously Evolving Road directed by Spirit in sacred service to humanity and the planet. Their world of sacred activism expanded through their deepening spiritual practice, their awaking up to the plight of humanity and Our Common Home, and their connection with others committed to a future that works for everyone.
Bob serves as a volunteer leader in a number of organizations committed to world peace, environmental and social justice and a true American democracy.
