If its the area thats above and below the 'Contact Details' text (as shown in pink in the attached screenshot), then its to do with a ratehr large lineheight set.
On line 333 of the css file p7HMY-01.css you have
.p7HMY .hmy-content p:first-child {
margin-top: 0px;
font-family: Verdana, Geneva, sans-serif;
line-height: 20;
}
If you remove the line-height line then you will lose all that white space.
Hope that helps and is about what you're treying to do
