Trauma Support

CPS Trauma Support

Below is a list of psychologists and social workers who participate on our trauma team and may be especially good matches for survivors of traumatic experiences of all kinds, including sexual or other physical violence, harassment, or discrimination. Keep in mind that if your situation is urgent and a particular counselor with whom you would like to work is not immediately available it is generally not wise delaying in seeking assistance.  Rather it is best to initiate treatment with a counselor who is more immediately available; you are always welcome to transfer to a different counselor at a later date.

SVR survivor advocates and prevention coordinators as well as other Columbia Health professionals can facilitate access to a member of the CPS trauma team; you need only ask.
