Long-time Mid-Columbia Council of Governments Executive Director John Arens has submitted his resignation.  Arens had been in the position for the agency that runs six programs for five Mid-Columbia counties for 15 years.  He says he wants to explore other professional opportunities.  Arens said he is remaining on the job until MCCOG can find a replacement.  He was unsure how long that would take.  Prior to taking the MCCOG position, Arens was the chair of the Hood River County Commission.
