Bill Frist joins California-based company's board

Lab testing company to roll out Walgreens services this year

Former U.S. Senator Dr. Bill Frist has been appointed to the board of directors for California-based Theranos, the company announced today.

Headquartered in Palo Alto, the lab testing company specializes in consumer health care technology and efficient blood testing. The company announced last year it was rolling out laboratory services in Walgreen's pharmacies nationwide, beginning in the Phoenix area last fall.

Frist serves on a number of other boards, including the Robert Wood Foundation, Kaiser Family Foundation and Harvard Medical School Board of Fellows. Mostly recently, he joined retinal technology company IDx's board in March.
