Content available only to specified users

Hello everyone,

I am trying to make certain content visible to staff members only. This is what I have so far:

<?php if ($current_user->ID == 1){ ?>
<!--this is what I want only certain users to see-->
<?php } ?>

This works great if I want this information visible only to the admin. However, we have more than one staff member. Is there a way I can enter multiple user IDs? Or is there perhaps an ever better way to manipulate the code?

Thanks.
