left nav dashboard only for admin users

how do I turn off the left admin dashboard for everyone except administrator users (i.e. ME)

I want my clients to have the custom admin bar, which is working well, but not have the "usual" things down the left side. even when I click hide on a bunch of it in the Branding, they still see

Dashboard

I want to place direct links on the admin bar and not have left side nav ... is this possible?

thanks!
