"This app is the best tool I have to help me understand and navigate my health benefits and healthcare needs all in one place. The concierge care team is friendly and supportive when I call in and their help really saves me time scheduling appointments. It used to take me 3 phone calls to find out where I can get the most cost-effective diagnostics, one to the provider, one to the insurance company and one to the doctor's it's just one."
