Our Team
David Bergeron
CEO, PRESIDENT, FOUNDER
David Bergeron has worked in the refrigeration and aerospace industries for 40 years. He holds three refrigeration patents, and three spacecraft patents, and is the founder of SunDanzer, selling solar powered refrigerators world-wide, based on technology he developed while working at NASA. Mr. Bergeron has served as the lead engineer on a satellite design for reentry and recovery, the lead engineer and project manager for the Lunar habitat solar power heat pump demonstration test article development, and was the technical lead for NASA’s Advanced Technology Refrigeration project, developing, testing, and evaluating thermoelectric, Stirling, and variable speed vapor compression cycle technologies. Mr. Bergeron graduated from Texas A&M University cum laude in 1982 with a BS in Mechanical Engineering and from the University of Houston CLC in 1985 with a Masters in Finance. David and Heather, his wife of 36 years, live in Tucson AZ. They have 5 kids and 3 grandsons.
Short Story from David: When I was 13 years old we had the Arab Oil Embargo. When I was 16, and driving my first car, we had gas lines. The lines made me realize how dependent we are on oil. It eventually drove me to study alternative energy. The Encyclopedia of Energy was my favorite book. In college, I focused on renewable energy as a mechanical engineer. I became the assistant to a fellow getting his Ph.D. on a solar thermal driven jet pump air conditioner. After that I was hooked on solar and refrigeration! After a brief 18-year career in aerospace building satellites (yes it was cool), I found a path to return to my first love of renewable energy and refrigeration, and have been doing that since 1999. I started part-time and continued aerospace work to make ends meet. After four years of running SunDanzer, we broke even financially, and we celebrated! After my 5th year, I was able to stop the aerospace work and focus 100% on SunDanzer and solar powered refrigeration.
Harrison Goold
CHIEF OPERATING OFFICER
As Chief Operating Officer at SunDanzer Refrigeration, I focus on strengthening our operations to consistently deliver bulletproof products for off-grid and vaccine storage applications. With a background in mechanical engineering from the University of Nevada, Reno, I take a systems-driven approach to scaling our design, manufacturing, and supply chain capabilities. My goal is to ensure every product we ship performs reliably in the harshest environments on earth. At SunDanzer, we don’t just innovate—we build tough, efficient, field-proven refrigeration systems that last. I’m committed to upholding SunDanzer’s values as we grow, ensuring that quality, integrity, and impact remain at the core of everything we do.
Jim Airola
Co-Founder and
Vice President Medical Projects
I’m a PH.D. economist who loves teaching and dealing with real world- especially developing world- problems. I’m particularly proud to represent and promote the product that SunDanzer has brought to the market to address a fundamental weakness in the vaccine cold chain.
Ian Tansley
Director of Medical Sales
Ian Tansley is a pioneering engineer with over 35 years of experience in renewable energy and refrigeration technologies. He invented the SureChill cooling system after observing how ice preserves water temperatures in nature, leading to a breakthrough in battery-free refrigeration. With early support from the Bill and Melinda Gates Foundation, he developed a solar-powered fridge that keeps vaccines safe for weeks without electricity. Under his technical leadership, over 30,000 units were deployed in 70 countries, supporting the delivery of more than 200 million vaccine doses. His work has earned global recognition for transforming cold chain reliability in the most challenging environments.
As Director of Medical Sales at SunDanzer, Ian applies his deep engineering expertise to ensure that the SolarVax product line delivers exceptional technical performance in real-world conditions. His hands-on experience with refrigeration system design allows him to bridge the gap between frontline health needs and robust, field-ready solutions. He brings a critical eye to product reliability, component selection, and system integration—ensuring each SolarVax unit supports SunDanzer’s mission of universal immunization access. Ian’s understanding of thermal systems and energy storage uniquely positions him to communicate technical value to NGOs and global health partners. His engineering foundation strengthens every aspect of SunDanzer’s medical sales strategy, from product development to long-term impact in the field.
