About Dr. Kat Green
Dr. Green’s work is grounded in the belief that children and families deserve access to treatments supported by strong research. Families often contact her after a child or teen has continued to struggle despite previous support, or when parents need a clearer understanding of how to respond to anxiety, compulsions, attention difficulties, or challenging behavior.
Her approach is active, collaborative, and focused on practical change. Sessions may involve the child or teen directly, parents, or both. The format depends on the person’s age, the concern being treated, and the role family responses may play in maintaining difficulties or supporting improvement.
In addition to clinical care, Dr. Green shares psychological education through Back in Charge resources, community presentations, professional consultation, and the training of future psychologists.
Clinical Specialties
Dr. Green specializes in assessment and treatment for OCD, anxiety, ADHD, and behavioral concerns in children and adolescents. Her anxiety work may include specific phobias, separation anxiety, selective mutism, avoidance, excessive reassurance seeking, and fears that interfere with school, friendships, family life, or age-appropriate independence.
For children with ADHD or disruptive behavior, care may focus on routines, reinforcement, communication, emotional regulation, following directions, and reducing patterns of conflict. Parent participation can be central because children practice new skills most consistently when the adults around them understand how to respond.
Clinical fit depends on age, symptoms, functioning, treatment history, and the level of care required. An initial consultation helps determine if Dr. Green’s services match the child or family’s needs.
Children, Teens, Young Adults, And Families
Psychological care changes across developmental stages. Younger children often need substantial parent involvement and support across home and school. Teens may participate more independently while parents remain involved in ways that support treatment goals. Young adults may focus on managing symptoms as responsibilities, relationships, education, and work become more demanding.
Dr. Green selects the treatment format after considering development, family circumstances, and the concern being addressed. She may work with an individual, meet with parents, involve family members in selected sessions, or coordinate recommendations for other settings when appropriate and authorized.
Education And Clinical Training
Dr. Green graduated summa cum laude from Brigham Young University with a Bachelor of Science in Psychology. She later earned her Ph.D. in Clinical Psychology from BYU, with an emphasis on child and adolescent psychology.
She completed an APA-accredited doctoral internship at Cypress-Fairbanks Independent School District. This was followed by a two-year postdoctoral fellowship at Texas Children’s Hospital and Baylor College of Medicine, where her specialized training included childhood anxiety, OCD, ADHD, and disruptive behavior disorders.
This combination of doctoral education, supervised practice, internship, and postdoctoral specialization prepared Dr. Green to provide both psychological treatment and formal assessment for children and young people.
Board Certification In Clinical Child And Adolescent Psychology
Dr. Green has held ABPP board certification in Clinical Child & Adolescent Psychology since 2019. The American Board of Professional Psychology currently lists her as a board-certified specialist in this area.
ABPP board certification is distinct from state licensure. It reflects additional specialty review beyond the requirements for practicing as a licensed psychologist. Dr. Green’s certification identifies her specialty specifically as psychological care for children and adolescents; it should not be described as a general board certification held by every psychologist at Back in Charge.
Her current board-certification status can be verified through the American Board of Professional Psychology directory.
Academic And Professional Experience
Dr. Green has served as an Assistant Clinical Professor of Psychology at Brigham Young University and later accepted a similar faculty position at Southern Utah University. Her academic work has included training future psychologists and helping connect research-supported practices with real clinical situations.
Her professional activities also include consultation with other providers, mental health education, community presentations, and membership in APA Division 53, the Society of Clinical Child and Adolescent Psychology.
