I used Dr Silva who is associated with Columbia University Medical Center, (he also works out of Bergen County, NJ.) He is excellent. I had no problems with surgery and he will explain everything. I have also met his associate Dr Beth Schrope who visited me in the hospital, who is also excellent (I have met people that she has done surgery on as well in my support group). Their website is www.obesitymd.org and they have alot of videos and info. (even if you decide not to use them, check out the website). Good luck.(I have United Healthcare and they were covered. By the way, Dr Oz works out of the Columbia University Medical Center, which includes NY Presbyterian Hospital and Columbia University Medical Center)
