WP MS 3.0.1 Profile question, can I call the Contact Info and how?

Within each site I have a admin specified within my MS 3.0.1 installation with their full profile filled out (First Name, Last Name, Nickname etc.).

I would like to have this information display within the header for some of the themes and automatically insert their Nickname for example for each individual WPMS site.

How do I do this?
