Why not call Jonathan now?

In therapy, the relationship starts at the very first contact, so I always prefer to speak initially on the phone rather than email; however, if you would like to register your interest by email, I am happy to call you back at your convenience. Please advise if your voicemail is private and whether I can leave messages.

Both of my telephone numbers have voicemail systems that only I can access so any messages will be private and confidential. If I call you back and someone else answers, I will maintain your confidentiality and not disclose why I am calling.
