617-326-3157 our main office several times a day requesting to speak with various personnel in Clinical Operations. When asked the nature of the call, the callers refuse to provide any information such as the company they are calling from, name of the person calling, return call number or the reason for the call and basically ask to leave a voicemail. Fortunately, the people that they have repeatedly call for, NEVER answer their office line unless it is business related and they recognize the phone number. Good luck getting a return call.
