Dr. Ryan is of the old school, very knowledeable, kind and patient. He wears a business suit, is wonderful at explaining things and giving precise instructions. He is direct and forthcoming and gets right down to tye facts and tells you what you need to do. I believe he is the best endocrinologust I have ever been to, his office is busy, he does your bloodwork there in his lab, your A1c is tested with just a finger-stick. I think he is the greatest, he I s not there to be your pal, b ut is the best, most knowledgeable doctor I have ever been to for my diabetes!
