Sequence research about how people experience the doctor's visit led to a significant finding: one of the worst aspects of the healthcare experience is all the waiting. So we asked ourselves, if that's the problem, how can we eliminate waiting altogether? There is waiting for an appointment time, waiting for providers when they're behind schedule, waiting to learn the cost of the service (and paying for it). Our answer? On Call, a concept service that puts the consumer back in charge of her time.
