About Joshua G. Kellison, PhD

Joshua G. Kellison, Ph.D. is a pediatric psychologist who joined Phoenix Children's Hospital in 2015 after completing a postdoctoral residency in Health Service Psychology with specialty training in program development and healthcare for lesbian, gay, bisexual, and transgender (LGBT) populations at the Honolulu VA. Prior to his experience with Veterans, he completed his doctoral internship residency in clinical psychology at the University of Washington/Seattle Children's Hospital. Dr. Kellison received his B.A. in Psychology and Critical Gender Studies from the University of California at San Diego. He completed his doctoral degree in 2014 with an emphasis in children and families in clinical psychology at Arizona State University.

Dr. Kellison has worked as a therapist within a variety of settings, and this has allowed him to also gain the requisite skills to work with children, adolescents, and adults with behavioral, mood, and developmental challenges. Kellison has special interests in LGBT populations, parent education, social skills, impulse control, anger management, and coping skills acquisition. He also strives to support children, adolescents, and families through transitional periods such as divorce, medical illness, and recent mental health diagnoses.

Kellison provides individual and family therapy to children and adolescents (ages 4-17) in an outpatient hospital setting, often with medical issues (e.g., cerebral palsy, diabetes, developmental delays), and co-occurring emotional/behavioral difficulties. He co-founded the Dialectical Behavioral Therapy (DBT) program where he provides individual therapy and co-facilitates a group for adolescents (ages 12-17) and their parent/s (Multifamily Group Therapy) with behavioral and emotional concerns (e.g., self-harm, suicidal ideation/behaviors). Services include behavioral health, counseling, parenting skills, self-care, substance abuse risk reduction, trauma focused, suicide risk reduction, and health education.

Beyond individual therapy, his work with LGBT populations includes the development of a LGBTQI support group (ages 12-16), conducting cross-sex hormone/puberty suppression readiness evaluations, and providing education to staff and the community on LGBTQ health and standards of affirmative care. His goal for PCH is to achieve Leadership Status in LGBT Health Equality from the Human Rights Campaign.
