MARION — The Marion Chamber of Commerce will be moving out of City Hall this spring to a historic building just a couple of blocks away.The move to the Lillis and Wilson Building, 1070 Seventh Ave., will “further the organization’s mission and create a visible presence in the historic Main Street District,” a Thursday news release said.The new office’s 2,800 square feet will provide conference rooms for meetings and programming and a business hospitality area for members to stop in for coffee, the release said.The chamber hopes to be fully moved in by June.The chamber has been in City Hall, 1225 Sixth Ave., since 2006 and before that was on 11th Street.“It’s no secret that Marion is growing,” chamber President Jill Ackerman said.
