Dr. Mohammadioun enjoys getting to work with individuals who are navigating significant chapters in their life whether it be transitioning into a new career, college/graduate schooling, relationships, or taking on new roles. He focuses on understanding what matters to his patients by collaboratively identifying their values, what goals align with their values, and learning new methods of relating to difficult thoughts/emotions that may act as barriers to taking committed action toward what is important in someone’s life.

Dr. Mohammadioun started his career in psychology at the University of Colorado in Boulder, majoring in psychology. This is also where he began working with Boulder Mental Health Services as a volunteer youth advocate. From there, his academic journey brought him to Berkeley, California where he completed his doctorate in clinical psychology at the Wright Institute. Dr. Mohammadioun recently concluded his pre-doctoral internship at Arizona State University where he provided psychotherapy and crisis intervention to students.

While completing his doctoral degree, he worked as a counselor at local schools and community clinics where he provided both onsite and in-home treatment to children with cognitive and/or physical special needs. He has a wealth of professional experience providing individual and group therapy to adolescents as well as adults. Dr. Mohammadioun strives to incorporate humor into his work while encouraging a sense of willingness to approach life’s challenges.

Dr. Mohammadioun is an Atlanta native who has lived in Colorado, California, and Arizona.
