I'm a 30+ adult and decided to go to Dr. Graber for orthodontic treatment. While I was quite impressed with his credentials (President, World Federation of Orthodontists, Faculty at Northwestern etc.) , his biggest asset is his friendly nature. He's quite cheerful and a good listener.
Dr. Graber has now moved to his clinic in Vernon Hills and no longer works at Kenilworth). Though it is a pain for patients who wanted to see him .. it's good as well. Previously the patient would get bounced around between two orthodontists and it didn't feel right.
Dr. Graber's facility and staff are very nice. But they do charge a premium. When I was shopping around for ortho, his prices were 10% more than the second highest quoted price. I still went for him based on his credentials and friendliness. Let's see how my teeth turn out finally .. will let you know!
