You probably need to edit – “.header-image #title-area, .header-image #title, .header-image #title a” which is around line 250…..the reason I’m pointing to this is because the height is 100px. Maybe reducing or removing it will help.
Also the #head-wrap (line 189) has a bottom margin of 20px. If you change both of those it will bring the slider right up with the header.
