Having trouble with machine, but we seem to be able to reply OK. Gordon would agree with George Lussier--one surgery at a time. Gordon's was done at the Oregon Medical School, Portland, Oregon, by Dr. kim Burchiel. he definitely stated one at a time and also, before the second surgery for his left side tremors, that there might be some speech problems and there were. Dr. Burcheil was a student of Dr. Laitenen, the Swedish neuro-surgeon. Everyone does not agree with Dr. Iacona, obviously. Good luck to you and we really don't wish to upset you. Thea and Gordon Seese
