  • Gregory Allen Willis

    I endorse this lawyer. Robert has been challenging the breath test in Florida for many years. His attacks on the breath test have been successful. He has helped countless clients that wouldn’t have had any chance of winning if they had hired any other attorney. I highly recommend Robert for DUI defense.
