Teresa I. Costa, PsyD

I am a clinical psychologist residing and practicing in the state of Oregon and licensed by the Oregon Board of Psychologist Examiners. I earned my doctorate in clinical psychology from the California School of Professional Psychology at Alliant International University. My first career was in the area of special education after earning my Master’s in Early Childhood Special Education from the Uni​versity of Oregon and my Child Development Bachelor’s Degree from Humboldt State University. For many years I have specialized with children and their families but have recently changed my scope of practice to primarily adults and with a focus on treating those with trauma in their pasts. I recently became certified by the International Association of Trauma Professionals as a Certified Clinical Trauma Professional. My volunteer work with SERV-OR has deployed me to Umpqua Community College in Roseburg, Oregon after their mass shooting event in 2016. My husband and I are both Veterans so helping the local Veteran population is also a passion. In November of 2015 I received specialized training in Cognitive Processing Therapy (CPT) from the Veterans Administration. CPT is a proven treatment for Post Traumatic Stress Disorder.
