What else would you like to say about your experience?
I can’t praise Dr. Koester enough. I told him and I meant it that he is an answer to my prayers. So many times doctors and other healthcare professionals treat us older patients with little or no understanding of our health needs or concerns. Dr. Koester listened. He was not patronizing or dismissive. He answered all my questions and made sure I understood. I never felt rushed. I am so glad my Primary referred me to Dr. Koester.

Dr. Koester seems very knowledgeable and caring. He does have a lot of energy and seems to want to jump in a lot when I spoke. I feel I get good care with him but I’m adjusting to his personality which is much different from my previous doctor who retired. Was very calm and attentive in comparison.
