One who has earned both an MD (Medical Doctor), as well as a Ph.D (Doctor of Philosophy). Double doctors are a rare breed, and you should always listen to them, because they know what they're doing.
Pleasure to meet you. Name’s Antonio Lucciali, medical doctor, and I have a Ph.D in physics. They call me the Double Doctor!
