Meet our Team

Reaching HOPE is dedicated to providing services by the most highly trained staff. We value the advanced doctoral training that psychologists receive, which is the highest degree available in psychology.  Therefore, Reaching HOPE is staffed only by Licensed Psychologists and Psychologists-in-Training who specialize in treating complex trauma. That means that all of our staff hold a doctorate degree, or are pursuing a doctorate degree (and already hold a master's degree). Here is our team:
