    Dr. Hesselgesser in my opinion is a doctor who does not treat his patients with the utmost care and proper diagnosis.He misdiagnosed me and 6 suffering weeks occurred. I have had over $6000.00 worth of dental work done due to his negligence. He misdiagnoses me and i was never told about the potential of tooth loss after radiation. On seeing bloody photos of my face from the radiation, he said, "Don't bring me those vampire pictures!" Dismissing my pain and anguish.

    I wish I could give Dr. Hesselgesser ten stars! He listens to the concerns of his patients and their families, takes the time to assess the situation, gives excellent advice and care. His expertise has completely transformed my mother's outlook and I cannot convey my gratitude enough. He and his team are top notch!
