    My high esteem for UCSF has increased even higher. I had a supurbly qualified physician who, not only gave me reasoned and sound judgements, but corrected an error made by my local hospital. I am so comforted by my zoom visit that will help me make a more reasoned decision about future health care. Many thanks for your quality standards!
