The magic of WordPress templates:
Just name your template file correctly, and WP does the rest!
Here is the code for displaying a single staff member. Name this page single-lt_staff.php.
To list staff members by their department, use this code for archive-lt_staff.php instead.
Because your client will be unhappy if they lose all their staff bios when they change to a new theme!
