“It was a new health care experience for me when I joined Cornerstone Primary Care. At my comprehensive first meeting with Dr Bernens, who reviewed my health records, coordinated my care with specialists and then reviewed their reports with me and made valued suggestions and follow ups. In addition, Dr Bernens called me at home to explain some of the more significant test results. It is a pleasure for me to recommend Dr. Bernens and Cornerstone Primary Care to patients who are looking for an outstanding primary care.”
