Outstanding doctor

September 05, 2018

Dr Kristo is a very concerned, compassionate doctor. He reviewed and examined all my health issues. He was not in a hurry but took time to listen to my issues and documented it all. This is a quality in a doctor that one does not find lately. Dr Kristo is a great doctor and I would recommend anyone to him. He truly is one in a million.
