"Dr. Castellanos not only specializes in this field because his heart is in it, but he is a perfectionist with his surgical technique. This isn't just my opinion, but the opinion of the hospital staff and xray technician who commented that he always does a \"pretty pouch\". He is confident that obesity is an addiction and treats it as such. Doesn't sugar coat anything, but is also sensitive and patient. Can't say enough good things. Only problem now is he is becoming so popular that he may be difficult to schedule with without a wait."
