Revised review: I posted the original review (and the picture of the inept front desk staff) from the waiting room. The woman who performed my echocardiogram (Wendy) immediately apologized and promised to address my issue. That made me feel better.
I had kind of forgotten how much I liked Dr. Loli until I saw him after the test. He promised me that the issue would be handled. I believe him. My point was and is that patients are people. Some of us can sit in a waiting room all day, some of us can't. Front desk staff clearly knew the technician was running behind, but no one told the patient. If I had that information up front, I would have been far less irritated.
The original review: The office staff are totally inept. If the testing person is running 30 minutes behind, why not tell the patient instead of letting him fume about the wasted time spent in the waiting room? The response of the front desk staff? "I wasn't the one to check you in." You can be assured I will find a new cardiologist immediately. (That last sentence is no longer true.)
