Location & Phone
For routine matters, the preferred methods of communication are phone calls or Signal which is an encrypted messenger app that may be used on your phone or computer. Email and standard texting are not secure and should not be used for sending private health information.
Messages and phone calls are typically checked Monday through Friday at 11:00 and 4:00.
