Would not recommend
Had a bad experience with Cornerstone Insurance Advisors. When I needed to file a claim, they were hard to reach and unhelpful. Ended up switching to a different broker.

Multi-policy savings
Combined our home, auto, and cottage insurance through Cornerstone Insurance Advisors. The multi-policy discount was substantial and managing everything through one broker is so convenient.

Reliable broker
Been with Cornerstone Insurance Advisors for a couple of years now. They handle our home and auto insurance well. Sometimes hard to reach during busy periods.
