Dusty Baker received his B.S. in Psychology from Drake University in 2008, and his Ph.D. in Counseling Psychology from Iowa State University in 2016.
He works from a humanistic and emotion-focused perspective, and views self-critical beliefs as the core to most concerns that bring people to therapy. Dr. Baker believes approaching their concerns from a non-judgmental perspective with self-compassion allows the client to feel safe in the exploration and incorporation of new perspectives that helps foster personal growth in the client's life. Honoring the client’s unique multicultural identity is also emphasized to better understand how self-critical beliefs developed and how those beliefs can be challenged with respect to each client’s personal and cultural values.
Dr. Baker works with a wide variety of concerns and has special interests in psychological assessment, ADHD, trauma, and vocational concerns. He also enjoys clinical supervision, teaching, and is a firm believer in the power of humor.
