Using a Contacts list field to filter a CMS-based repeater

Question:
I want to have a CMS-based repeater that only shows the records related to the user. So I want to access a custom field in the Contacts table (MentorID) to filter the CMS table driving the repeater to only show the relevant records. How do I refer to / access the MentorID for current user in Contacts and use to filter on current page?
