Robert D. Beyer, the chairman of a private investment company, has been nominated to the Los Angeles Board of Airport Commissioners (BOAC).

In announcing the appointment Jan. 18, Mayor Antonio Villaraigosa said Beyer, the chairman of Chaparal Investments LLC, brings decades of experience in business management as well as overseeing operating, financial and real assets. Beyer would replace former commissioner Alan Rothenberg.

“His unique combination of experience in business and investment management will serve our airports well as we strive to modernize and operate them successfully, to improve services to travelers, and to remain competitive in the global market,” Villaraigosa said.

Beyer will join an Airport Commission that is currently overseeing the modernization of Los Angeles International Airport (LAX), including the Bradley West and Central Utility Plant projects, improvements to all the other terminals, and the updating of the LAX Master Plan.

During his investment career, Beyer has been responsible for the management of large, diversified and global businesses, a spokesman for the mayor said. He has held oversight positions managing more than 1,500 employees and 100 different public and private market investment strategies and has had responsibility as a portfolio manager in various investment categories.

He also serves as chair of the Board of Visitors of the UCLA Anderson School of Management, as a trustee and immediate past chair of Harvard-Westlake School and as a member of the Board of Councilors of the USC College of Letters, Arts & Sciences. Beyer is also on the board of directors of the Los Angeles World Affairs Council where he oversees management of the endowment.
