"Dr. Volak is the best ! He is every understanding and listens to all your concerns.He answered all of my questions in great detail. He was not rushed but rather took time to make sure I was at ease about my upcoming procedures. Some visits are very serious and can be quite frightening. It’s great to have a doctor as caring as doctor Volak in your corner. I highly recommend and his team."
