“The U.S. has one of the most intimidating and complex healthcare systems possible, without a consistent, proven, and quality outcome. Patients deserve an advocate who will not only help them navigate the system steering them to the best possible outcome but who will also play a role in changing the way healthcare is delivered in this country.”
