Why are you passionate about CSC?

When I was in college I learned about CSC and the work that was done. What struck me was that advanced scientific technologies were being used to directly impact patient care in a primary care setting. As someone who has an interest in genetics, it also struck me that genetic information was being generated and used in a very practical way. When I started working at CSC, it became even more evident to me that the lab and clinical staff worked hand in hand to try and reduce or eliminate the barriers (cost, lab turnaround time, distance, etc.) that prevent patients from receiving high quality, personalized care. It is an honor for me to support and be a part of those efforts.
