Dianne Carmichael is the president of Best Doctors Canada, a medical advocacy service that offers second opinions to over 5 million Canadians through employee benefit plans. Best Doctors helps patients get the best care from the public healthcare system by gathering medical records, reviewing them, and consulting global medical experts to catch misdiagnoses or recommend alternative treatment options. In 2009, Best Doctors correctly diagnosed Ms. Carmichael's mother with a cyst rather than the surgery that was recommended, allowing for a less invasive procedure. Ms. Carmichael believes partnerships between public and private healthcare can help make universal coverage sustainable by reducing errors and utilizing business innovations.
