Reply To: Reducing Space Between Header Graphic and Content

In your style.css file, look for .site-inner around line 601 –

.site-inner {
	background-color: #fff;
	clear: both;
	margin-top: 170px;
	position: relative;
	z-index: 9;
	-word-wrap: break-word;
}

You can lower the margin-top and it will decrease the space.

Let me know if that helps.
