We were attracted to Concerned Business Services LLC years ago by an ad that stated: "Public Safety Employees--- We will review your returns for the last three years and amend them, if necessary". That statement is correct. They reviewed our filed tax returns for those past three years and adjusted them to our great benefit. We are very happy then and still are with the service that we still receive. B & T Bagley, retired Firefighter/Captain, Palm Desert, CA
