What drew you to naviHealth? As a childhood cancer survivor, I spent a lot of time in hospitals. I received the highest levels of coordination across care facilities, leaving me with the impression that this was standard operating procedure. Instead, as I’ve grown older and dealt with aging parents, I’ve learned that we are far from treating our elderly like we do our children (or even pets!). I wanted to be in a place that can help make healthcare a seamless experience for any population.

Who is your role model in innovation? It’s a toss-up between Steve Jobs and Coco Chanel, who created the two essentials – the iPhone and the little black dress!
