Matthew Duff

Matthew Duff earned his Doctorate of Psychology in clinical psychology from Biola University in 2025. He completed his doctoral internship at the university counseling center of Montana State University, where he worked with primarily young adult students representing diverse cultural identities. As a postdoctoral fellow at Dayspring Behavioral Health, he splits his time between assessment and therapy, primarily serving adolescents and adults of all ages.

Matthew is extensively trained in psychodynamic therapy. For Matthew, that means that the relationships people have with one another are a key part of the highs and lows people encounter in life, and that exploring clients’ experience of relationships past and present—family relationships, romantic relationships, and friendships alike—often illuminates ways forward through difficulties. Matthew also encourages concrete, solution-focused problem-solving with clients, and he has a high regard for the gentle power of an empathetic, understanding connection between people. As a therapist, Matthew practices a synthesis of these approaches to meet clients where they are and engage them in their own healing process and personal growth.

In therapy, Matthew works collaboratively with clients to navigate depression, anxiety, trauma, loneliness, and the stressors that relationship, school, work, and life can bring. Matthew believes that a strong therapeutic rapport—that is, a therapist–client relationship that is warm, positive, and trusting—is foundational in therapy. Matthew values building such a relationship with clients and using it to explore the relational, cultural, physical, mental, and socio-emotional factors that can help facilitate clients’ success.

When giving psychological assessments, Matthew is passionate about relationally connecting with clients and using assessment results to help people better understand themselves and connect with resources relevant to their needs.

An Issaquah native, Matthew enjoys running, hiking, and taking any excuse to play outdoors in the beauty of the Pacific Northwest. He currently lives in Puyallup with his wife, who shares his passions for psychology, people, and Christian spiritual formation. He loves writing and language—he once bought a dictionary for fun—and in his spare time enjoys board games, science fiction, cozy murder mysteries, and quality time with friends.
