Client Doesn't Know Google+ Brand Page Manager Login - How to Recover

[WebTalent]

Hello - I'm working with a client who has a complete Google+ Brand profile setup for their business, but cannot locate the google+ login associated with the management duties of that page. Is there a way to track down or at least to see who the page owner is and their associated email address?

I believe you can just claim the listing with another account anyways. You'll just need to re-verify the address with the postcard PIN.
