She actually pulled up the liver photo on her computer and explained, in non medical terms, what my liver was having a problem with! This was SO very reassuring to me. Also, on my first visit with her, she asked to see my daughter because it is genetic- passed from mother to daughter- how impressive is that?❣️❣️❣️

Dr. Bartnik is a true professional. My advice is, don’t do anything that would make her want to leave your employ.

Dr Bartnik has been excellent in helping manage my care. Really like how she communicates and I have a strong feeling that she's looking out in my best interest and presenting and discussing next step options. My wife who is a doctorate level CNS also really likes these meetings and between the three of us we always leave on the same page. Her team and especially Kylie Dennis have been excellent and they both visited me at some of my hospitalizations.
