    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.
