I didn't get a warm feeling from Andrea and she seemed very hurried. But the worst piece is there was no follow-up after my apt.
Never felt rushed; very professional demeanor in interacting with an anxious patient (me)
Dr. Kossler is amazing in all ways
I drove all the way from San Francisco to Stanford for a second opinion and to hopefully have some of my questions answered. Instead I felt like I was wasting the doctors time and inconveniencing her. Didn't ask if I had any questions or let me talk much, instead she seemed very rushed, talked very fast and quickly looked over my CT Scan and didn't look at anything that the nurse did before her. She was in and out of the room in 2 minutes. I felt like I just wasted my time and I didn't get any questions answered.
Tech provided competent info and assistances during test.
Dr. Kossler is amazing.

Not the most friendliest doctor, e.g. she did not say hi when she came into the surgery suite or even when she started working on me, however I can tell she is truly knowledgeable and an expert in her field and I have complete confidence in her as a doctor.
Dr Kossler spent a long time with me explaining the possibilities for my diagnosis, and she even brought in another expert in the clinic to help get a second opinion.
