Dr Posner was kind and patent. She listened and research my previous tests, she spoke to me about my previous tests and her concerns. She had suggestions. I have had issues with previous Dr's (specialists) that tell me to live with it, its too small to fix, and have left me feeling so defeated, and helpless. Dr. Posner is the only Dr that has really gave me hope. I will forever be thankful and I assure you I will refer her to ALL of my friends!
