Dr Iberri is an excellent communicator. I get my questions answered thoughtfully and thoroughly. He also has excellent support from his office staff.
Dr. Iberri is excellent! Very engaging and shows great concern for his patients. We are very glad he is our oncologist!
Once again, I am so grateful Dr. Iberri is my oncologist. I think he is taking very good care of me. He is very positive, cheerful, great sense of humor. He puts my husband and me at ease. He's obviously very smart!! Multiple myeloma is a complicated disease. I watch quite a few webinars trying to learn about the disease, and frankly I sometimes feel I am just becoming overwhelmed and more confused. I ask Dr. Iberri questions about things I've heard in these webinars, and he very patiently listens to me, and then explains "the whys and the wherefores" about his treatment decisions for me. He often sites studies that have been done on whatever my "topic du jour" is. I suppose all Stanford doctors are up-to-date on the research in their fields, but who knows, maybe not! I'm very appreciative that he seems to be knowledgeable about what's going on "out there" with respect to this disease. Again, maybe this is a "given" and stupid to say, but I'm a lay person entrusting my care to Dr. Iberri, so any hints of his extended studying of the disease is good news to me! It's of great relief to feel your doctor is very good and deciding the best for you.

Dr. Iberri showed us my recent PET scan & compared it to the original from Sept. 2015. Both his explanations & seeing the actual scans was very informative & helpful.

Dr. Iberri and his "gang" are SUPERB.
I like the doctors, he is so friendly and accommodating. I really understand his explanation about my problem.
