I really like Dr. Klein and find him to be extremely knowledgeable with a wonderful bedside manner. However, the administrative staff needs improvement. In early July, my husband left a voicemail message wanting to make an initial patient appointment, and they never called him back. They claimed they did call back, but I think they called the wrong number. They described hearing a voicemail greeting that would never have been from my husband. Then recently they sent me a bill for two visits for which I had already made the copayments. When I called to question this, they said they hadn't yet applied my payments to my account. This was for visits in June and July! And, the person I spoke to didn't even apologize for sending an incorrect bill. They need to clean up their administrative procedures, which are unprofessional and sloppy.
