Disney’s board just became bigger and more diverse: Directors voted to increase the membership to 11 with the addition of Maria Elena Lagomasino, the CEO of financial advisory firm WE Family Offices. She’ll become an independent director beginning December 1 and will stand for election at the next shareholder meeting.

Lagomasino is a familiar name in governance circles. She’s also on the boards of Coca-Cola and Avon Products. In addition she’s a board member for the Americas Society, a Trustee of the National Geographic Society and a member of the Council on Foreign Relations.

At Coke she chairs the Compensation Committee — and found herself in the middle of a controversy last year when she and others supported a surprisingly large employee stock plan. It was trimmed after several major investors including Warren Buffett objected to its terms.

Disney CEO Bob Iger calls Lagomasino “a respected leader in the finance and investment field and also has a wealth of experience with, and keen understanding of, global consumer brands.”

Before founding WE, Lagomasino was CEO of wealth management firm GenSpring Family Offices. She also was CEO of JP Morgan Private Bank. Private Asset Management recently named her one of the 50 most influential women in wealth management. In 2007 Hispanic Business magazine named her its Woman of the Year.
