The Greater Danbury Chamber of Commerce has new leadership.  JoAnn Cueva is now acting President of the group.  Board of Directors Chairman Jim Arconti says the change was made on Friday.  Cueva is also a member of the Chamber's Women's Business Council Steering Committee.  In that capacity she has organized several events promoting women in business, including seminars on leadership.  One of the Council's signature events is called "Conversations with Extraordinary Women" which this year featured Gretchen Carlson.
