Welcome to the Q&A Forum

Having too many links is the least of your worries on these pages. Looking at the view source there's a lot of code (508 lines of it) clogging up the bots path to any content, let alone the links. Your menu structure is over complex from a code point of view, the pages are rendered in tables, there's a lot of on page JavaScript that could be minified and/or accessed thru a separate file,  I don't see an tag here's the link to one of your stylesheets Your example About Us page scores a very low 57/100 on Google's page speed tester - that alone could be a reason the pages aren't being indexed well. Looks like programmers we're driving the bus when the site was built.
