in Cotati, CA |
Dr. MacDonald is terrific doctor. I have a rare autoimmune liver disease and have progressed abnormally very quickly. He's up on the latest research and treatments and keep great communications open between my care team and me. I confident that if/when the time comes to get a liver transplant, I will be in the best hands possible to arrange MELD score evaluation and process. I would recommend Dr. MacDonald to anyone needing a gastroenterologist.
