jachilles on "Move sidebar up to the top"

I am new to WP and i am trying to adjust the sidebar and move it up the top of the page where the is extra white space.

On this page i want to move the blue sign up now button to the top of the right column where the extra whitespace is and it would be inline with the about header.

http://crossfitkitsilano.com/about/ and a couple other pages all with the same custom sidebar.

I am able to do it in Firebug by shrinking the header to 650px and a - margin on the button.

Still learning the WP editor and a bit stuck.

Really appreciate the help for a new user to this.

Thanks
