The Mayo Clinic Board of Trustees met Nov. 10 and re-elected its leadership.

The 31-member board met in Minneapolis for a quarterly meeting and elected Samuel Di Piazza to continue in the role as chairman for another four years. Di Piazza is the retired CEO of PricewaterhouseCoopers.

He joined the board in 2010 and became chairman in 2014.

"Samuel Di Piazza has provided strong leadership to help Mayo Clinic chart a successful course amid a rapidly changing health care environment," Mayo CEO Dr. John Noseworthy said in a media announcement. "He's helped elevate Mayo Clinic's national and global profile, while preserving our organization's strong mission, culture and values. Sam has encouraged us to think ahead, think big and turn outward to identify the best ideas to perpetuate our mission, while still staying true to our primary value."

The Mayo Clinic Board of Trustees, a 31-member group of public representatives and Mayo Clinic physicians and administrators, is the governing body of Mayo Clinic.
