Dr Feiner took the time to go over my complicated plan of care. He downloaded my insulin pump and even talked about my insulin pump how it was being programmed. Dr Feiner had samples of other insulin pumps and literature to give out. He is a very fine doctor that is very attentive to the concerns of his patients and I would highly recommend him.
