Does anyone use Oak Street Health for their health care provider?

4. Spouse and I both have original Medicare

and fortunately where we live, most doctors, those in large clinics as well as individual practitioners, accept original Medicare. Ours has been our physician for many years, so we are fortunate in that sense. It is a shame that no one is answering your request for a call back. If nothing else, you could drive over to the office itself and mention that you have been waiting for a phone call, and after so many days you decided to come in person to get an answer to your question.
