    She was the must rude doctor I have ever had. When she did finally join the call she was sitting back in her chair away from the computer so it was hard to hear you. Her body language and tone of voice was unwelcoming. Very closed off. Annoyed and make me feel stupid for asking questions. She didn't introduce her self. She joined the call and just looked at me waiting for me to say something. So I said hi and so did she. Then the silence began again. We just looked at each other. I was very confused and waiting for her to start the conversation. And said said " do you have any questions " I was dumbfounded and confused and asked if she read my chart and she said yes. Then more silence and staring. It was a complete waste of my time and awful bedside manors

    Pre-surgery meeting with anesthesiologist. She was outstanding. Listened well, helpful and a kind unhurriied energy (even though I'm sure her schedule was full)

    Dr. Chern demonstrates a rare combination of brilliance and empathy. She explains complex medical issues with remarkable clarity and takes the time to understand our concerns. She has a calming presence and a genuine ability to alleviate our anxieties. She helped us feel seen and heard. Meeting with her is always a positive experience.

    The doctor recapped the exam but I was hoping to see that summary in the after visit summary. For example did she have an estimate on size of tumor. She tried to answer all of our questions but she did not want to over step questions I should get from my oncologist and I understand that.

    This provider seems to have a personality issue. I don't think she really tried to be callous, but it came across that way. She seemed most interested in trying to force her point of view and not take mine into consideration. I am also a physician, and therefore I would've expected more respect from my opinion then she was willing to share.
