Disappointing experience
I was disappointed with Cornerstone Insurance Services. They took over a week to get back to me with auto insurance quotes and the rates weren't even competitive.

Couldn't be happier
Switched all my insurance to Cornerstone Insurance Services last year. Better coverage, lower premiums, and they handle all the paperwork. Couldn't be happier with the service.
