What People Say About Dr. William Zigrang, MD
Dr. Zigrang is both my Endocrinologist and my PCP. He only acts as a PCP if ones insurance company agrees which appears to be more rare than standard. I make appointments for an annual physical exam in addition to my quarterly diabetic office visits. For awhile his office has been totally electronic as part of the Sutter Health My Health Online App & website. I have usually used the built-in email function to make appointments and request prescription refills. I see my lab results online.

×Post a ResponseAre you Dr. William Zigrang, MD?
In all the years I went to Dr. Zigrang, I had one physical. All the other times all he did was write in long hand the results of tests that I had-I also had the results so it was a waste of a copay and my time. In addition, he would only refill prescriptions if I made an appointment. His pleasant personaliy could not make up for his ineffectualness.
