Superior Service

“During the purchase of a new house, I took the opportunity to shop my insurance, as my current provider’s quote was over the top. I looked at several of the major, well-advertised carriers besides getting a quote from Texas General. Texas General not only beat the others significantly in price, but the policy was with a well-known, nationwide carrier and they made the switch quick and easy. I have been with them for two years now and have no complaints.”
