Yes, Dr. Z was very, or Zei, I'm not sure how to pronounce his name, was very thorough, very understanding, seemed extremely knowledgeable. I'm not sure what else to say. He was patient and listened. I had my daughter with me, answered questions that she had, and etc. Your question about, you know, how likely would you be to refer this doctor, he's a specialist, so I'm not even a regular cardiologist. I guess he's a special cardiologist. So, you know, someone needed his services, yes, but I'd be unlikely to know anyone who would necessarily need his services, but I certainly would if I did. That's all I really have to say.
