About Doyle Trading


Stephen Doyle/President
Steve formed Doyle Trading Consultants in 2002 to provide coal and emissions consulting services to the energy and financial sectors. From 1983 - 1997, Steve was based in New York City and active in the global coal sector as Vice President/General Manager of Ruhrkohle Trading Corporation's export division and as the President of Integrity International. In 1997, Mr. Doyle left that sector to become one of the pioneers in the nascent OTC and futures market in coal and emissions, establishing trading desks for Peabody, Vitol/Avista, Sithe, and Allegheny Energy. In 1998, he traded the world's first domestic and global coal swaps. In subsequent years, he played an essential role in bringing coal and emissions trading to the mainstream energy players. He is a past president and current member of the New York Coal Trade Association.

Sherry Orton/Emissions Analyst
Sherry graduated Magna Cum Laude from Mesa State College with a B. S. in Physics in December 2007. Her undergraduate research was in thin-film photovoltaics and solid state physics. A passion for studying the practical aspects of renewable energy made her the natural choice for DTC's 'greenhouse gas girl' when she began working for the company in the fall of 2007. Sherry now closely follows both the global and domestic emissions markets (SO2, NOX, CO2 and mercury) as well as developments in the clean coal technology arena. She is currently working towards a graduate degree in Materials Engineering.
