Tressa D Stiles PsyD | Kaiser Permanente

I mainly practice from a cognitive behavioral therapy/dialectical behavioral therapy framework, because I believe this offers the client a variety of life changing skills. My training and work experiences range from juvenile detention centers and jails to an inpatient hospital and community based mental health center.
