    The Dr is great, the staff was very nice EXCEPT FOR DIANE the receptionist. She has a nasty disposition. She didn’t even say hello to me when I entered and barked out orders of the materials she wanted from me. She’s a miserable robot and when artificial intelligence replaces her the world will be a better place because the AI is sure to have more humanity than her .

    Dr. Hatz is always professional and thorough and I’m glad he was recommended to me after Dr. Bagan passed. Even his bedside manner is loosening up a bit with some humor. Would recommend him to any of my friends looking for a good GP.
