HealthTap.com has recognized me as the #1 physician in the U.S. for the topics of "Perfusion Scan" and "Health Statistics." I am also #1 in the Seattle, Washington area (this extends up to Bellingham) for the topics of "Diabetes", "Diabetes Risks" and "Heart Diseases."
These rankings are arrived at in part by participation on their website answering patient questions. This is a quick way to ask physicians and other medical professionals quick and basic questions on health care topics.
