“The appointment of Bob Rivers to Eastern’s board of directors recognizes his many significant contributions to our organization, particularly in the areas of community leadership and the acceleration of our innovation efforts, which have further elevated our brand and better positioned us for future growth,” Eastern Bank Chairman and CEO Richard E.
