contact accordian list web part

I have a custom list that is showing contacts. I have the following fields in the list

Room Name: Scooby

Phone Number 000-000-0000

Location: New York City

On my page I want to show it as

New York City

    Scooby: 000-000-0000

Philly

    Snoopy: 000-000-0000

and so on, but I want to show it in an accoridian web part and have collasped on load. Is there a way to do this reading a custom list and show as i have above?
