I had my AN removed 2 years ago at John Hopkins. I found it to be an excellent hospital. The staff there is professional, very helpful, courteous and attentive. Look up Drs. Raefael Tamargo and Lloyd Minor, they are quite experienced and come highly recommended. The hospital has all kinds of services, from transportation to housing if needed. I am into my 3rd. year of followup and everything so far is looking good. good luck!
