Dear Mr. Malone,
Thank you for visiting the MadisonCounty MedicalClinic on Monday. I hope that you were satisfied with the level of service and care that you receiveD、As you requested in our recent phone conversation, I have included a scanned copy of the medical certificate, signed byDr.Edwards, as an attachment to this email.
Should the electronic copy of this document be unacceptable to your employer, I will post the original document to them directly. Please let me know if this is necessary. Please note that, in the future, I recommend that you request a copy of your certificate when you see the doctor. This is much simpler and more convenient for everybody.
Regards,
Grace Sylvester
Secretary — MadisonCounty MedicalClinic
