I’ve been a patient of Dr. Hays since 2008 when he came to CPMC. In 2012, he moved to UCSF, and became Heart and Lung Transplant Director there. I followed him to UCSF, and was able to become a patient of the program and received my transplant in 2014. The cumulative team itself is amazing, but I have to thanks Dr. Hays for advocating my case forward there. He believed in me, and therefore gave everyone else confidence to proceed in evaluating, listing and transplanting me. If you want an intelligent, diligent and caring doctor, he is your guy. He is younger, so a bit more approachable and flexible and welcome to new and innovative treatments, or to at least consider them without just throwing them out. He attends seminars and conferences regularly to stay up to date, as well as puts on educational conferences of his own in the area. He is patient with my questions and requests for more explanation, but most important, he listens to me. He has been my favorite and most faithful doctor in my lifetime of receiving care for my complicated pulmonary disease history. I truly recommend Dr. Steve Hays for anyone seeking out a pulmonary/transplant specialist, the bonus being you have the entire Heart & Lung Transplant & Pulmonary teams at UCSF in addition to his medical expertise and manner.
