Excellent professional care.
Providence Health & Services Patient

It is very difficult to schedule appointments with this provider. I often have an appointment to schedule in 3 months. The calendar does not go that far out. At first the scheduler said he would call me back.. He didn't. When I called back another scheduler told me it was my responsibility to make that app't. Then I had to wait another month to get an app't. Please clone Dr. Zemsky and add more ablation schedulers and more regular schedulers as your system isn't working. But Dr. Zemsky is worth the hassle and frustration.
