Dr. Jonathon Shasteen, PhD, MS is a psychology postdoctoral resident who works with children, adolescents, and adults to build habits and skills that improve brain health and quality of life. Dr. Shasteen empowers others by helping them foster a strong foundation of daily behaviors such as exercise, social interaction, and sleep hygiene, while also identifying solutions to specific life challenges unique to every individual.
Dr. Shasteen found his life purpose after taking an introduction to psychology course as an 18-year-old college student. He was not only fascinated by how the complex human experience is nurtured in a 3-lb brain, but also amazed by how much his life improved when applying a greater understanding of behaviors, thoughts, and emotions. Every day since, Dr. Shasteen is inspired by helping others use this knowledge to create the human experience they want for themselves and the people they love.
Dr. Shasteen holds a PhD in School Psychology from Oklahoma State University. He completed his doctoral internship at Trevor G. Browne High School in the Phoenix Union High School District. Additionally, Dr. Shasteen holds a Master of Science in Psychological Sciences from The University of Texas at Dallas, as well as a Bachelor of Science in Psychology and in Child Learning and Development from the same university.
Dr. Shasteen has provided a variety of psychological services in a variety of settings, including primary schools, secondary schools, universities, private practice clinics, and crisis centers. He has extensive experience performing disability evaluations, neuropsychological testing, individual and group therapy, and consultation with parents, teachers, and other stakeholders.
Additionally, Dr. Shasteen has contributed to the field through academic research and instruction. Beginning in 2011, he led university studies to increase social understanding and social functioning in adults with autism and schizophrenia. His research projects since have focused on the prevention and treatment of depression and anxiety in youth, and how this can be implemented in widely-accessible settings (e.g., schools). Dr. Shasteen’s academic contributions also include teaching university courses on child/adolescent development, among other topics.
