Dr Bassim is wonderful. I came to the CC for a third opinion because I thought I was out of treatment options and was getting no where with the ENTs in Buffalo, NY. Dr Bassim gave me hope, treatment options and knew exactly what I was explaining, which was different than any other ENT doctor I've had care for me. He is an extremely knowledgeable and thoughtful doctor. I am so thankful to have found him at the CC and he has taken over as the primary specialist provider for my care.
