Chamber receives distinguished award.

The Board of Directors were presented with this plaque for their outstanding support of the 2014 Marine Corps Reserve Toys for Tots program.  In addition to this plaque they received a Commander’s Award for generous contributions that have enabled the Marine Corps Reserve Toys for Tots program to bring the joy of Christmas and send a message of hope to America’s less fortunate children.

We thank every business who participated and every person that donated.  The Marengo – Union area campaign was successful in providing for the community.
