HOW WE DID IT: This list is produced in partnership with Crescendo Business Services, an independent research firm. Crescendo mailed ballots to and called 17,000 area residents who had recently purchased homes. Recipients were asked to nominate only insurance agent professionals whom they know through personal experience and to evaluate them in two categories: overall satisfaction and whether they would recommend them to a friend. Crescendo scored and screened each nominee based on these evaluations. Each agent is qualified against the Texas Department of Insurance to make sure their licenses were up to date and there had been no disciplinary action. The resulting list represents 1.3 percent of insurance agents in the area. Finally, we turned the list over to our sales team. They cannot add or subtract from the list, but they can sell ads to the winners.
