I felt heard and Dr Ham always gives it to me straight even when I may not want to hear it and I see it is difficult for him. Messages are always returned In a timely manner. He is compassionate and well educated /informative about any issue I discuss. As a nurse myself, he not only meets my expectations but surpasses them.
