Pia Quimson-Guevarra, DO
I am a board-certified psychiatrist; a medical doctor who specializes in mental health. I graduated from medical school in 2013 from Western University of Health Sciences in California. I completed my psychiatry residency training at Oregon Health and Science University (OHSU) and pursued additional training in Forensic Psychiatry. My interests include community and forensic psychiatry.
​
At Quimson Behavioral Health, I provide clinical services in a supportive environment to promote emotional wellness and growth. I provide more than just a "medication check" appointment. I employ a balanced approach which includes medications, education and talk therapy.
​
I specialize in helping those with anxiety and depression to get to a better place. I also help others explore the impact of society, culture, and relationships on their mental health. I am a BIPOC/AAPI/Asian provider and identify as Filipina-American.
​
My philosophy is to provide a supportive environment to encourage self-care. I help you explore your thought patterns as it relates to your feelings and actions. At times, this may be difficult, but processing and accepting these emotions will move you forward toward healing and growth. Types of therapy I employ include Cognitive Behavioral Therapy (CBT), Acceptance and Commitment Therapy (ACT), Compassion-Focused, and Psychodynamic/Psychoanalytic.
Cayley Mesterheide, PA-C
As a certified Physician Associate (PA-C) specializing in psychiatry, I have experience with evaluating, diagnosing and treating a wide variety of psychiatric disorders and enjoy working with patients of all ages and backgrounds.
My passion for psychiatry began before I started PA school while working as a nursing assistant in the psychiatric unit of a hospital. While working at the hospital, I achieved my Bachelor of Science in BioHealth Sciences degree at Oregon State University. I then went on to pursue my Master’s in PA Studies at Lipscomb University in Nashville, Tennessee.
My approach to treating mental health is holistic and includes a focus on medication management while incorporating supportive therapy and lifestyle modifications. I strive to connect with each and every patient and make it my goal to ensure that they feel heard and understood. Helping patients to find the right therapeutic regimen that allows them to function best in life brings me fulfillment in my career. I look forward to meeting and collaborating with you to help you achieve your mental health goals.
