Keystone Mental Health Services


We are happy to announce that our Keystone Team is re-entering our building as a space to deliver mental health care.  Contact through telecommunication methods can continue for some clients, as is appropriate.

Our top priority is the well-being and safety of our staff and clients.  As a result, we have prepared our space to be sanitized and to safeguard our health.  Also, we have implemented new in-office practices for serving clients.

When your appointment is scheduled, you will be asked about you and your child’s health symptoms, based on CDC identified symptoms related to COVID-19.  At arrival, you and your child’s temperature will be taken.  We have our space set up to enable and require social distancing, wearing masks, and frequent hand washing/sanitizing.  Scheduled clients will receive more details from our Intake Coordinator and their assigned clinician.

We welcome the return of clients to our offices, and look forward to continuing the provision of critical mental health care to the community!
