    Please note that this is my Multiple Myeloma specialist, not my PCP or my local Oncologist. This was a two year post bone marrow transplant check. Dr. Maziarz is the doctor I've seen at OHSU pre, during, and post transplant, however only annually now.

    Dr. Maziarz has seen me through my stem cell transplant with a positive attitude, extreme knowledge and it has been successful. I couldn't have asked for better.

    We have been at this for years. I am also a retired bio-based researcher; the conversations are as simple or complex as the situation warrants.

    This was my first visit with this doctor. He was friendly and kind and had good experience to discuss available options. He also spoke in simple language so that we could understand. We are looking forward to working with him.
