Crater Lake Institute's Board of Directors

Ron Mastrogiuseppe received a B.S. degree in forest science from West Virginia University and an M.S. in forest ecology from Humboldt State University. Ron worked for the National Park Service at Sequoia-Kings Canyon, Crater Lake, Olympic, and Redwoods National Parks as a naturalist/interpreter. At RNP, Ron worked as a forest ecologist in the park restoration program. Following his retirement, Ron began promoting the idea of the Crater Lake Institute.

Owen Hoffman graduated from San Jose State College in biological conservation, received an M.S. in fisheries limnology from Oregon State University, and a Ph. D. in ecology from the University of Tennessee, Knoxville. Owen worked as a park ranger-naturalist at Crater Lake, Zion and Yosemite National Parks from 1966 until 1971. Since 1998 he has performed work as a volunteer at Crater Lake National Park for both the NPS and the CLI.

Rod Cranson served as an interpretive ranger at Crater Lake National Park for seven summer seasons. Rod received both his Bachelor of Science and Master degrees from Michigan State University in preparation for a career in petroleum geology. However, the opportunity to teach Earth Science in high school led to a career in education, including 27 years in the Science Department at Lansing Community College.

Larry Smith is a tireless worker for Crater Lake National Park, serving on the board of the Friends of Crater Lake, having worked as a ranger naturalist at Crater Lake National Park, and having taught 5th graders in Jacksonville, Oregon for 33 years. Larry worked two seasons at Crater lake National Park on Roads and Trails, 7 seasons as a Park Interpreter, and 14 seasons as a Park Ranger General in Park Protection and Law Enforcement.

John Salinas started his work at the park as a seasonal interpreter from 1978 to 1982. During that time he assisted Doug Larson with limnological studies of Crater Lake, something that provided an impetus for Salinas to eventually complete his master’s degree at Oregon State University. After an absence lasting two summers, he returned to the Park in 1988 and continues his intermittent role in the lake research program under contract. The ever-versatile Salinas continues to teach a field studies course for Rogue Community College in the park each year and has regularly contributed to Nature Notes from Crater Lake. His articles in the latter encompass subjects as diverse as the Old Man of the Lake, the Whitehorse Ponds, and a repeat photography project.
