Dr. Dieterich and his NP Allison are so professional and compassionate. They took the time to explain the fibroscan in a manner that related to my specific situation. They put me completely at ease and answered all my questions. They each came to the waiting room to provide me wlith results of the procedure. . Thank you.

Dr. Dieterich is EXCEPTIONAL!!!! I went to see him because of some concerns about elevated liver enzymes. He looked at the whole picture, not just numbers on blood tests or me physically. He asked me at what times I was taking certain medications. I mean, his approach is different and top-notch. I would definitely recommend him!
