Add Shipping State to Contact Form?

On our Contact Form, we have the Account Name. How do I add the Account's Shipping State to the Contact detail page and the view list?

We have a sales person who needs to know what state the Contact is located to make calls at an appropriate time.

I know about the Reports where you can put both Account and Contact information on the same page, but in her case, it requires opening a second window - to view the Contact detail page, and it is not convenient for her.
