DS in NB
I haven't heard of any bariatirc surgeon in your province doing the DS, but I'm not in your area so there could be someone I don't know about. The DS surgeons in Canada who are best known are Dr. Gagner in Montreal, and Dr. Marceau's group in, I believe, Laval, Quebec. There is also a Dr. Hong in Ontario (I forget which city, but not Toronto) who does the DS.
