Justin Wyckoff, Ph.D., Staff Psychologist

Psychology, BA, Oklahoma State University
Community Counseling, MEd, University of Oklahoma
Counseling Psychology, PhD, University of Oklahoma

Providing counseling services has been the focus of both my training and career as a psychologist. And though I have worked in a variety of settings including, I have found the experience of supporting clients through university counseling centers to be the most rewarding and exciting. At the UCC, I work with clients who present with a diverse range of concerns including mood disorders, anxiety disorders, navigating life transitions and relationships changes, identity, and trauma. Regardless of the reasons bringing clients to counseling, I seek to provide an empathic, collaborative therapy experience emphasizing the development of a deep understanding of client identities with a commitment to facilitating personally meaningful change, growth, and knowledge of self.

I also have an interest in supporting the development of psychology trainees at all levels through supervision and didactic trainings. My approach to supervision is largely influenced by the Integrated Developmental Model of Delworth, Stoltenberg, and McNeill. As a supervisor, I endeavor to build a supportive and understanding supervisory relationship that includes honest, developmentally appropriate feedback grounded an understanding of each trainee’s personal strengths and areas for development and their personal training goals. I would describe my own theoretical orientation as rooted in cognitive perspectives though integrative in nature using aspects of CBT, ACT, MI, DBT, and IPT. However, I enjoy discussing clinical conceptualizations and approaches to intervention from a variety of perspectives and aim to support trainees in developing their own perspectives and orientations.
