If a patient is using voice mail, cell phone or email to communicate with the office staff or therapist, please be aware that we cannot guarantee the timeliness of receipt of the patient's communication. Please do not leave emergency or crisis messages on voice mail or email. Ensure that the therapist will receive your message by calling the office during regular business hours. If you call the emergency cell phone number after office hours, a therapist will try to return your call as soon as possible, but in the even that you do not receive a call back quickly, you are directed to the nearest emergency room.

Also be aware that all email communications are printed and retained in a patient's chart and in the record of the internet service provider. Cell phone and email contacts are not as secure or as confidential as communications made during appointments or calls through land telephone lines. To ensure confidential communication, wait to talk directly to the therapist.
