Dr. Kozberg was exceptional. We traveled from Florida to see her because of her reputation and knowledge in CAA-RI. Being in the medical field myself, I was so impressed with Dr. Kozberg's professionalism and care. She was more than gracious with her time, listened to all our concerns and explained everything with an empathetic heart.
