GWU hospital for surgery?

has anyone been to dr. Paul Lin at the george washington univ hospital? i had a consultation with him about 2 years ago.  Or any of the doctors at the johns hopkins hospital? 

or can anyone give me a name of a really good doctor for RNY?!?! i am confident that next year my surgery will happen! i want to know my options for good doctors. 
Also, i would really love to meet someone in real life who has had the surgery. i live near columbia MD. 

 i am having rny @ GW- with dr. Brody-I can say is it is a gastric bypass center of excellence- only a small % of centers  are rated this hight.  I have only been up there about 2 times. they seems sharp.

no lost patients etc.-- I asked! 

 thanks for that! i really want to have it done at gwu. i want a place that has a very low mortalitly/morbidity rate.  what is dr.brody like? dr. lin was very straight forward and business like, not a bad thing but not a warm personality.

chech with DR> AFRAM he great and the director of gwu beside maner is the best so is his staff
