I think the problem is that your header image file is in the wrong place. When I look at the url for the image - it looks like it's in the images folder. ... yourhealth.com/wp-content/themes/atahualpa/images/grapekubrickheader2.jpg That is, I think you replaced that little weird green flower logo (the default logo) with your grapes header image. And that pushed everything else out to the right.
I think what you've done is gone to
Atahualpa Theme Options / Header Area / Style and Edit Header Area
and then in the Show Logo Image area, replaced the default logo.png file with your grapekubrickheader2.jpg file
Perhaps try reverting back to the default logo.png image in that section.
Then upload your header image to the correct place, in the header folder located here:
Also, I read somewhere that header images should be 1300 x 160 max and yours is 901 x 237. Maybe try to reduce the height?
