Former state treasurer John Chiang has joined the board of Apollo Medical Holdings, an integrated population health management company in Glendale.

Chiang served as California State Treasurer from 2015 until earlier this month. He began his career as a tax law specialist for the IRS.

ApolloMed also named Linda Marsh to the board. She is currently vice president for AHMC Healthcare, overseeing financial matters for seven acute care hospitals. She is also responsible for all federal, state and local government relations, as well as all risk management activities for AHMC.

"We are honored to welcome Ms. Marsh and Mr. Chiang to our board of directors,” stated Dr. Warren Hosseinion, co-chief executive of ApolloMed, in a statement. “Drawing on their years of experience in the health care industry and government relations, (they) will provide fresh insights to our company as we continue to grow.”

The appointments became effective Thursday. Shares of ApolloMed (AMEH) gained 79 cents, or 4.2 percent, Friday to close at $19.58 on the Nasdaq.
