Reduce size of Banner t top of web page

On the website my view shows a half-page banner horizontally, which leaves little space to view content.

The banner shows the logo and Madison MAN Co-op at top, then a statement: BUILDING ECONOMIC AND COMMUNITY STABILITY TOGETHER IN A NETWORKED COOPERATIVE FOR DOING THE WORK WE WANT TO DO     then lots of empty space, then a horizontal menu of:

Calendar  About   Contact  Marketplace   Member Directory 

It's all good info but it would be helpful to take up less space so one can view the content better.
