About Us

"I have had nothing but positive experiences with Ken and Pat for several complex projects for three different organizations: Cal Poly, EVC and California Space Authority. They recently completed a business plan and economic impact study for the California Space Authority's Space Center Project, a $220+ Million proposed project near Vandenberg Air Force Base. As a Board member of the CSA, I was very pleased to see the quality of their work on this difficult project, and to learn that the CSA executive team was also very pleased with their work."

Kenneth D. Riener, PhD

Ken is a Principal for Productive Impact LLC. He holds a doctorate in Finance and Masters in business from the Krannert Graduate School of Industrial Administration at Purdue University, and a Bachelor of Science in Mechanical Engineering from the University of Idaho. He is a retired Professor of Finance in the Orfalea College of Business at California Polytechnic State University, San Luis Obispo, where he has taught since 1983. During his tenure, Dr. Riener was the lead researcher in the study, "Source of Income, Generator of Human Capital, and Economic Stabilizer: The Economic Impact of Cal Poly on the City and County of San Luis Obispo, California, 2002-03." This study estimated the direct and indirect impact of Cal Poly on economic activity and job creation, demonstrating the effect of Cal Poly's presence as a stabilizing economic force. It calculated the increase in earning power of San Luis Obispo residents, due either to their Cal Poly educations, or as a result of the increase in average educational attainment of the residents of SLO County. This study was actually the culmination of a series of Economic Impact studies overseen or co-authored by Dr. Riener, dating back to 1991. He has also authored or supervised studies of the economic impact of the Mid-State Fair, of the proposed Cal Poly Research Park, and of the California State University System. Dr. Riener served on the Steering Committee for the "Study of the Economic Impact of San Luis Obispo County Non-Profit Organizations," sponsored by the United Way of San Luis Obispo County. In addition, Dr. Riener created the Entrepreneurial Finance course at Cal Poly, and has been teaching it since its inception. In April 2006, Dr. Riener mentored a team that wrote the "Petrolects" business plan, which won the Ray Scherr Business Plan Competition.
