Our vision is to be the trusted partner solving complex benefit challenges.


Let us help you simplify your life.

Cornerstone’s business model was born two generations ago on handshake agreements and that’s how we do business today—by keeping our word. Our mission and company culture is based on integrity and excellence. At Cornerstone we do what we say we are going to do and then some. As a family-run business, we believe our brokers deserve not only excellence, but accountability, honesty, and empathy along with it. In this business, we pride ourselves on our determination to treat others with respect and deliver results exceeding our brokers’ expectations as our core philosophy.

—Jennifer Agnello, President
