Google Adding Wrong Location to Title Tag on Multi-Branch Business Homepage

[Doylejg3]

We're a business with 5 separate locations across 5 cities in Upstate NY.  While doing some visual ad previews in the adwords interface I noticed that Google is altering my title tag and adding the word "Rochester" to the end of it, cutting short my designated title tag.

Rochester is the location of our headquarters so not a big deal for 1/5th of our customers.  But to my dismay, the same thing is happening when searching from the geo locations of my other branches.  So when searching for my business in Buffalo (we have a physical address in Buffalo), the title tag in the results still says our company name and "Rochester".

This of course is likely leading to confusion and actively harming our organic CTR in our branch locations.  This is happening in all of the remaining 4 branch locations.  I'm at a loss, I tried lengthening the title tag but it still gets cut off.

The term Rochester appears (as do the other branch locations) in my meta description for the homepage as well as in the text of the page itself.  I haven't gone so far as to remove that yet and hopefully don't have to.

Does anyone have any ideas?  Thank you in advance!

So, since I first posed this question i've tried adding schema structured data illustrating that the page is associated with 5 distinct locations.  Been over a week and the problem persists.
