Kelly P.

We have been with thorntonpowell for many years even when it was on 95th St in Oak Lawn. Insurance can be risky but with the proactive folks at thorntonpowell we do not worry about being over priced or any other issue. We cannot say enough about how we trust T and P. It is one of the few businesses that my wife and I completely trust. In this economy, that is rare. The employees of this company truly look out for its customers!
