Extracting custon values from the aspnet_profile table and placing them in a dropdownlist

Hello Forum
I've recently used the CreateUserWizard to add firstname, middlename and lastname to my aspnet_Profile table.   I was wondering how I would go about placing these values in a dropdownlist (ddlEmployees) so that I may wind up with a list displaying these values  concatenated, eg. Mary Anne Brant, Joseph Ezra Shultz etc.  That's the firstname, middlename and lastname from the profiles table. 
Thank you
