    1. 1 *Wayne Keiser.
    This last visit has me questioning whether this is the proper oncologist for me.
    EXCELLENT doctor, except for the waiting time in the examining room.
    *Dr. Keiser is an excellent doctor.
    Things felt different in the office this time (I have been going in for follow-up visits post ovarian cancer and previous felt VERY comfortable); this time felt Dr. seemed to feel rushed & not able to take the time that was needed, almost like overly aware of the clock, as if someone was secretly watching him, which is too bad. He is a WONDERFUL physician. The other staff members seemed pressed as well. (Not a change for the better in my estimation.)
