Delta Gamma also has various levels of alumnae groups: hope groups, associations, and chapters.  All are identified by geographic area.
Alumnae chapters have an officer structure similar to that of collegiate chapters:
president, vice president: membership, vice president: programming, treasurer, corresponding secretary, recording secretary, Panhellenic delegate.  There may also be chairs for Foundation (philanthropy events), collumnae (activities with nearby collegiate chapters), and special interest groups: young alumnae, book club, dinner club, "mom and me", bunko, bridge groups etc.
