When I first saw Dr. Nguyenduc he was very nice and listened to my concerns, did a great job with the procedure and follow up.  A few months later I went back with upper GI concerns and all he did was criticize my eating habits and told me to quit drinking.  Number one as I tried to tell him is that I dont drink and number 2:  I eat a clean diet, all organic, veggies, white meat and no dairy.  He would not listen.  Was very disappointed at this visit.
