All that I did was go to the AMA site and choose the 'Find a Physician' button and entered his name James Thompson, Dallas, TX and it brought up his page which only had the same address as the FBSC. I'm just going to send my letter there.
Of course, we do not know for a fact if Dr. Thompson will have further input on the bill. He testified as 1 of 6 from the medical/le field during the initial hearings before the House.
