Guardant Health (https://www.guardanthealth.com/) is the world’s leader in “blood biopsies”: blood tests that track tumor genomics and identify treatment options. As CUEO I was responsible for ensuring that Guardant's products are engaging for all of our customers – not only our physicians, but also our patients, their families, advocates, and anyone whose life is touched by cancer. I also oversaw our marketing department, working to advance our brand as the world’s leader in liquid biopsies, identifying new products for the product portfolio, and supporting sales in their efforts to reach the oncology community.
