Basically it's my initials and name. AMD = Doc + Hamm. The last name is borrowed from my spouse. He's the real Hamm (pun intended). I used to be called Doc as far back as I can remember, for several reasons. Again my initials, my inate ability to fix things, build things, my study of medicine, sports trainer, my love of philosophy and more. I seemed to have gained a reputation for creating, fixing, repairing and being good at various things.
