Dr Teng (Las Vegas, NV) is great.
Now I don't have bariatric surgery experience with him. However, he was the surgeon that performed my cholecystectomy in August 2010. He does great, phenomenal work! And I'm not sure this is a big factor to anyone but he is the Chief of Surgery (since 2001) as well as the Medical Director of Bariatrics (since 2006) at his hospital.
I read that sometimes (if not all the time) there are tests run on your gallbladder for stones or something? I'm not sure what this all mean because I'm relatively new. But I think having the same surgeon do both my gallbladder removal and my VSG gives me a continuity of care that nobody else could provide. It may sounds nuts but I want total comfort as I get major surgery done. And as far as I'm concerned, he is the BEST in Las Vegas. No offense to other surgeons but I just feel more at peace with him and his surgical team.
