Marshal Lieberfarb's Reviews

It would've been nice if the doctor reviewed my previous MRI where the tumor was existing two years prior to this event. It seemed like you pretty much rushing to get the cyber knife on me. Once I had a complaining with another neurologist I guess he pointed out to me I was a little setback. Thanks all outside of that I think it was great.


I am having a bit of a problem with follow through. It is almost a week since my visit and the MRI was not scheduled and the order has not been sent to my urologist so that hormone therapy can begin.


Emphasize that not all side effects happen to every patient.


Can't think of anything. It was all very professional coupled with empathy.
