Reviewed on Mar 29, 2019

Both my husband and I can not say enough good things about the Cleveland Clinic. Having a central place for the patient to get all their test results, lab reports, electronic images, and doctor's notes would be a good improvement - especially for those of us that have traveled hundreds of miles from our normal medical providers/facilities. Just a thought, not a complaint. I did manage to gather up most of my records.

Rhe doctor carefully explained his reasoning to me and then I understood better.
