David Hasemyer is a freelance journalist whose career includes an award-winning tenure at the San Diego Union-Tribune as an investigative reporter.  His work has been recognized by the Associated Press, the Society for Professional Journalists, the Society of American Business Editors and Writers and the California Newspaper Publishers Association. He has also been a finalist for the Gerald Loeb Award.

Among the articles Hasemyer researched and wrote for the Union-Tribune was a series about a 10-million ton pile of nuclear waste, a remnant of the uranium-mining boom in the 1950s and '60s that threatened the Colorado River. Those stories have been widely credited as critical to the U. S. Department of Energy's decision in 2000 to move the pile away from the river. Hasemyer graduated from San Diego State University with a Bachelor’s degree in Journalism.
