View connections in template

Hi Guys,
Is it possible to list the connections on another template (not a single or archive page)? For example I have a Contact page and in this page I want to list Staff that work in an office.
My connection is

p2p_register_connection_type(array(
			'name' => 'staff_to_office',
			'from' => 'staff',
			'to' => 'office'
		));

In mysql what I’d like to achieve will look like this
SELECT * FROM staff WHERE office_id = 123

I would like to pull out all the information in this manner using WP_Query (on the same page)
