I would have preferred to have spoken to my Doctor rather than a PA. Don't get me wrong, she was very nice but this is a trying time for someone diagnosed with cancer, you want your Doctor.


Review follow up care plan better


When the appointment is at 0745 at the staff's assistance do not make the patient wait 10 minutes. Have smaller wheel chairs available.


Everyone was very professional...Can't think of any thing that could have been better!
