Gregory Stangl, CEO of Phoenix Energy, has been working in the energy and environment field since early 1999 when he led the buyout and subsequent turnaround of Energy Investors, a firm dedicated to improving air quality in Europe by replacing coal furnaces and improving facility energy efficiency.  Developments in Europe led the business into the biomass gasification arena, such that in 2007 Phoenix Energy was spun out to focus exclusively on that market in the US.  Prior to his work in the energy and environmental field, Mr. Stangl worked for several years as a venture capitalist based in Paris and Warsaw and for the UN Development Program in Central Europe.  During his venture capital career Mr. Stangl has served on the boards of several European companies.
