Tab Section title area scroll

Hi There, We are facing some usability issues with the tab section.

For example, We have appx 9 tabs in the tab section. however, users see only 5 items in the title area at a time. http://thirtycapital.wpengine.com/portfolio/ (hosted on WPengine)

is there a way, we can have them in either 2 rows so that users see all tab titles on the screen or have a arrow that denotes there are more tabs? Currently, only when you click the last (rightmost) tab, you will realize that there are more tabs.
