In this time of unrest we feel it is important to say that we as professionals and Pennsylvania citizens believe that equality is designed to be and should be a part of our community and our nation. And clearly, there has not been racial equality in how our nation operates despite our current laws. 

We stand with the protesters in asserting the need for change in police accountability via legal and administrative means. This will serve as a model for our citizens who have embraced prejudice knowing there will be little to no consequences.

We as healers can only be effective if there is true safety for the black community. We urge you to help us create the safety that is essential for healing by standing with those who are breaking through our nation's denial via active protest.
