Integrative Psychology Group, LLC

An innovative, multi-specialty psychology practice

Dr. Gina Mattei, Assessment Supervisor


I am Dr. Gina Mattei, a Licensed Clinical Psychologist at Integrative Psychology Group and an Assessment Team Supervisor. 

My specialty is child/adolescent clinical psychology. I have 8+ years of experience working with children and their families in both outpatient and school settings. I focus on providing comprehensive psychological assessments that help clarify diagnosis, identify strengths and areas for growth, and create personalized treatment plans. I am a strong believer in the family system as a primary support for the mental health of children and teenagers; as such, my treatment focus is providing parent training, family therapy, and behavioral interventions to address difficult symptoms. I treat anxiety, OCD, depression and other mood disorders, post-traumatic stress/adjustment concerns and have a lot of experience working with neurodiverse individuals (e.g., those with autism spectrum disorder, ADHD, intellectual disabilities, learning disorders, and language processing difficulties).
