Dr Posner and his team saved my husbands life. When we were told my husband had cancer we were in shock and disbelief. Dr Posner explained everything to us and his treatment plan was top notch. I would advise anyone who has been diagnosed with head and neck cancer to see Dr Posner.

The doctor spent time with my husband and even came into the examining room during his appointment with the surgeon in order to provide further input on his case. We are very grateful Dr. Posner.

My husband was treated by Dr. Posner in 2005 and was truly a kind and caring man. He tried and did everything he could.Although I lost my husband in 2007 I had him 2 years longer than expected due to Dr. Posners care.We drove 4 hours a day so he could be treated by him.
