Ida Moadab, Ph.D.
Ida (she/her) has provided mental health services in Eugene for over ten years. She earned her Ph.D. in Clinical Psychology at the University of Oregon, and completed her predoctoral internship at the VA Puget Sound Health Care System at American Lake and her postdoctoral residency at Stanford School of Medicine. She is also a graduate of the Behavior Therapy Training Institute (BTTI) run by the International OCD Foundation, which provides specialized training in OCD by experts in the field. Throughout her training and continuing education, she has emphasized evidence-based approaches, which include Mindfulness-Based Cognitive Therapy, Acceptance and Commitment Therapy, and Exposure/Exposure and Response Prevention. She hopes to help clients develop a kind, self-compassionate way to manage life’s difficulties, and learn to identify and fill their own needs. Her goal as a therapist is to help people grow into their authentic selves through development of self-awareness and strategies that help them overcome difficulties to live fuller, more meaningful lives.
She works primarily with adults across the lifespan, and works with clients with anxiety (including Specific Phobia, Social Anxiety, Generalized Anxiety, Panic Disorder), Obsessive Compulsive and Related Disorders (including OCD, Skin-Picking, and Hair Pulling), and trauma-related disorders, including trauma related to chronic experiences of racism and discrimination. As an Iranian-American, she is dedicated to helping people of color, who can have negative experiences in therapy if they feel their therapist is not validating their experiences of explicit discrimination and implicit microaggressions.
In addition, she completes and supervises psychological evaluations, assessing for ADHD, learning disabilities, and differential diagnosis, among other issues.
When she is not working, Ida enjoys spending time with her two young children and partner, listening to music, making elaborate and poorly decorated cakes, and being outdoors.

Multicultural Facilitator | Licensed Psychologist
Ron Miyaguchi, Ph.D.
Supervisees: Tyree Dingle, PhD
Ron (he/him) received his B.A from the University of Hawaii and his M.A. and Ph.D. in Clinical Psychology from Miami University in Ohio. He has worked at university counseling centers in Ohio, Maryland and Oregon. The primary models that inform his therapeutic approach are Cognitive-Behavioral Therapy, Acceptance and Commitment Therapy, and Interpersonal Therapy.
People often come to therapy because we do things that we know are not in our best interests, like letting our anxieties talk us out of doing things that are scary but necessary. Yet even when we know this, we still get caught up in our old, frustrating patterns. Ron’s therapy approach is to begin by exploring the non-logical beliefs (think of them as assumptions, expectations and perceptions) that we have about ourselves and the world around us. Usually this entails looking at a person’s cultural, familial, and personal histories in non-blaming, non-shaming ways. The most important part of the therapy experience, however, is in helping clients take the steps that are necessary to disprove these beliefs and to learn new, more empowering ones. Often this means supporting clients as they gently push themselves into situations that challenge their old, limiting ways of seeing themselves and their world.
Ron works with clients teenaged and older, with a focus on anxiety, obsessive-compulsive disorder, depression, emotional intimacy, and identity issues. He has a strong interest in cultural competence and cultural humility and recognizes the impact of the sociocultural context on a person’s functioning and well-being. He also offers workshops that help individuals and organizations become more culturally attentive, aware, and inclusive.
When not working, Ron’s self-care includes knitting, baking, and cycling, and running around kicking a ball in a manner that almost resembles soccer.

Her style is active, meaning that she balances listening and empathic support with gentle challenges, exercises, and ideas for maintaining therapeutic growth outside of your therapy sessions.
Chaunce specializes in treating Anxiety Disorders (e.g., Specific Phobia, Social Anxiety, Generalized Anxiety, Panic Disorder) and Obsessive-Compulsive and Related Disorders (e.g., OCD, Skin-Picking, and Hair Pulling) in adults.

Clinical Social Work Associate
Austin Kaiser, LCSW
Austin (he/him) is a cognitive-behavioral therapist specializing in the treatment of anxiety and anxiety-related disorders, depression, and self-image problems. He earned his Master of Social Work degree at Pacific University. Before joining ECAS, he worked with adult clients between the ages of 18 and 80 at both the Center for Community Counseling in Eugene and the Counseling Center at Lane Community College.
Austin believes that most of our emotional problems derive from our beliefs about ourselves, other people, and the world. These beliefs are developed over the course of a lifetime and determine how we respond to adversities, daily stressors, and other challenges. We often act on these beliefs (particularly those related to our acceptability and worth) without being aware of them, but they can be brought to the surface,
evaluated, and changed through the therapeutic process.
In his work with clients, Austin emphasizes the importance of discomfort tolerance, unconditional self-acceptance, and living in accordance with one’s values. He sees therapy as a collaborative process in which clients take an empowered and active role. He enjoys working with adult clients of any age, in a manner that is inclusive and culturally informed. He holds primary and advanced certifications in Rational Emotive Behavior Therapy (REBT) from the Albert Ellis Institute, and a Level 1 certification in TEAM (Testing-Empathy-Assessment-Methods) CBT from the Feeling Good Institute. He has also completed the Beck Institute’s four-course clinical sequence in CBT.

Licensed Psychologist
Jason Feinberg, Ph.D.
Jason (he/him) earned his PhD in Clinical Psychology from George Mason University, completed his predoctoral internship at the Pacific Psychology & Comprehensive Health Clinic, and his postdoctoral fellowship at Portland Psychotherapy. Jason specializes in treating individuals with anxiety and obsessive-compulsive-related disorders. In his therapeutic approach, Jason uses evidence-based treatments such as Acceptance and Commitment Therapy and Cognitive Behavioral Therapy. In particular, he has extensive training and experience implementing Exposure Therapy (i.e., Exposure and Response Prevention), which is the gold standard intervention for anxiety and obsessive-compulsive-related disorders.
Most of the people Jason works with struggle with anxiety and fear in some shape or form. As a result, their lives have unintentionally become more focused on avoiding certain situations, thoughts or feelings and less focused on connecting with their loved ones, values, and life goals. To name a few examples, he has worked with folks living in fear of: encountering different social situations, discarding items that hold sentimental value, and touching surfaces that they consider “contaminated” in some way. As a therapist, he finds it incredibly rewarding to help people develop effective strategies that help them feel less limited by anxiety and fear, and thus do more of what gives their lives meaning.
While he primarily specializes in treating anxiety and obsessive-compulsive-related disorders, Jason also helps people navigate issues such as depression, trauma, shame, and life transitions. As a queer therapist, he has a particular interest in, and has significant experience, serving other LGBTQIA+ and queer folks. In addition, with all of his clients he explicitly invites discussions regarding how our cultural backgrounds, lived experiences of oppression and privilege, and current socio-political events influence our lives and how we show up in the therapy room.
When not working, Jason enjoys playing tennis and pickleball, learning new board games, and spending time outdoors with his dog Pixie.
