Dr. Hay is simply the best. I have been his patient for 10+ years and could not imagine receiving better care. He is everything one would wish for in a physician. All of the adjectives that apply the the greatest doctors in the universe apply to Dr. Hay. He is indeed a blessing to those of us fortunate enough to have been in his care!

If you are lucky enough to see the Mighty Dr. Hay, then consider it a blessing. The man saved my life and has been extraordinary in his ongoing care. If ever there was a Doctor that symbolized perfection; it would be Dr. Hay. When I think of the expertise of Mayo Clinic, I think of Dr.Ian D. Hay and the angels that work for him. He is the best Doctor.(Period) He cares, he has patience, he is the expert, and he gets things done. You can't ask for anything more, but you will get it from the Mighty Hay.
