There are two ways to do this. Click on the contact name in your search results it will pull up a screen view for that contact. Once on the screen view, click on the “Go To Company Name” button in the upper right-hand corner of the screen view. This will bring you to the company profile screen view. On this page click the “Contacts” option, this will allow you to build a search for contacts at that specific company.
The second way to do this is from the "Key Companies" tab. You can go directly to a company profile if that company is listed in your search results Key Companies, by clicking on the desired company name.
