C. A. O. is actually the initials of Cano A. Ozgener, the founder of the cigar co. Tim Ozgener is the president of the company based out of Nashville, TN. If you are ever going to Nashville set up a tour of the place it is really neat to see and they are very nice people. I had a great visit in January and got to try a special blend while I was there. Make sure you try a Camaroon from CAO. I like the Toro (5 1/2 x 55) Nice smoke..
