    Dr Stephen Hays is wonderful. This was a 2nd opinion and I feel like he really carefully reviewed all of the reports and findings as well as listened to my recount of symptoms and treatment so far.

    Dr. Steve Hays is beyond superb. I count him as one of the absolute top lung transplant pulmonologists in the country. And I have seen many others so my opinion is based on true patient experience. I am a very complex triple-organ patient with a complicated auto-immune disease. There is not one aspect of my overall health that Dr. Hays hasn't addressed researched advised on appropriate MD referrals etc. Clinically professionally and personally he is a gem.

    Dr. Hays is tremendous doctor. He so caring and thoughtful of my situation. He tries his best to take into consideration of the distance I live from San Francisco. I consider myself very lucky to have Dr. Hays as my doctor.

    I have literally had hundreds of Doctors in my lifetime and Dr. Hays (as well as most of the Doctors at UCSF) are definitely at the top of my list of greatest Doctors!

    My condition is still in question but treatment is proceeding. The most immediate concern was establishing oxygen here at my new home and that has been troublesome. Dr. Hays did check in with assigned Nurse and while she told him there was a "glitch" I wish he had asked for specifics to inform me. I finally spoke to nurse and realize I had given her a wrong number she didn't have time to call me. I could have easily resolved it and prescription could have been filled if I knew that.

    Dr Stephen Hays is simply the best physician I've ever had. Smart compassionate and gives me an honest assessment of my condition. He literally saved my life pre transplant by getting me focused on my condition ( I was in denial) and post transplant is on top of every item that pertains to my condition.
