Retired Colonel Joe A. Isenhower was a founding member and director of IMMG; his member number was #2 (Bill Ewing was #1). Joe has been a generous supporter of the Museum and is a Life Member. He was trained as a soil scientist and served in the Soil Conservation Service after his military career. He was involved with Fred Schute in the birth of IMMG and served as an early Board president. He also designed the IMMG logo!

Robin has had an almost lifelong interest in geology. He earned a Master of Science degree in Geology from the University of Idaho in 1993. He has worked in the mining industry since that time, exclusively in gold mines, both epithermal type (near surface hot spring vein gold) and Carlin type (disseminated micron sized gold) deposits. The majority of his work has been logging core, turning exploration drill core into digital data for use in virtual computer graphics programs that model the ore bodies underground. This requires an expertise in: mineral identification, structural regimes, rock alteration types, lithology identification, and related computer knowledge.

Robin is a past president of the IMMG Board of Directors.

Troy works as a freelance writer, researcher, and editor; he began his writing life at a very young age, penning the as yet unpublished George and the Giant Castle at age six. He grew up in Southern Idaho, and after many adventures including a short stint in the US Army and a diverse education, Troy returned to Idaho, and currently resides in Boise. He has had extensive museum management experience with the Wallace Mining Museum in northern Idaho. Troy served on the IMMG Board of Directors before transferring to the Advisory Council.

ChairShirley Ewing joined the IMMG in 2004 and within a couple years was on the board and deeply immersing herself in all aspects of the museum. Her late father, Bill Ewing, was one of a small number of Founding Fathers of the IMMG, and Shirley felt she could carry on his love of Idaho mining and geology by volunteering at the museum. Shirley retired from the Boise Independent School District in 2003, having spent the last 19 years as the principal at Pierce Park and later Cynthia Mann schools. After two years as volunteer Museum Manager, Shirley has accepted the position of Chairperson of the Council and will remain active in Museum affairs as the supervisor of internships, advisor to the Operations Coordinator and a general resource for public relations and the Rock Party.
