KaiserAir Leadership Team
Ronald J. Guerra
Chairman of the Board
Ron joined Kaiser Industries as a co-pilot in 1961, flying a DC3 for the company executives and Kaiser family members. He quickly advanced to Chief Pilot and captained the growth of both the flight staff and the acquisition of many aircraft with global capabilities. Ron and his team not only pioneered international business jet travel (they flew the first corporate jet into Beijing, among other notable firsts), but they were much sought after for their aviation management, pilot training, safety, and maintenance skills.
Ron deftly persuaded many Fortune 100 companies to operate their aircraft under the umbrella of the Kaiser flight department. The Kaiser flight department experienced rapid growth in its aircraft acquisition and management services, positioning itself under Ron's guidance as an early and substantial player among the largest Part 91, 135, and 145 operators in the western United States.
"KaiserAir" emerged from the dissolution of the Kaiser companies in 1979. Ron exhibited his loyalty to the Kaiser legacy by incorporating the Kaiser name into his newly established aviation firm, and he brought over his entire team which formerly comprised the flight department. Over the next four decades, Ron oversaw the expansion of KaiserAir, establishing two Bay Area Fixed Base Operations at Oakland and Santa Rosa airports. In 2011, KaiserAir achieved a significant milestone by becoming the first new airline at Oakland Airport in over 50 years.
Ron's professional influence extended to serving on the Gulfstream Advisory Committee, as well as serving on the Board of Directors and various committees for the National Business Aircraft Association (NBAA). Ron’s legacy includes pioneering more than 40 aircraft modifications on Gulfstreams, Hawkers, Falcons, JetStars, LearJets, and Citations.
In 2005, Ron was honored with the NBAA's John P. "Jack" Doswell Award for his steadfast dedication and remarkable accomplishments that played a pivotal role in advancing the objectives and standards of business aviation. Ron retired from the professional cockpit with a remarkable flight history that encompassed over 21,000 hours and spanned six continents.
Ron remains at the helm of KaiserAir providing daily leadership along with a team of skilled aviation professionals, including several second-generation family members.
