Gina Mattei, PhD

Licensed Clinical Psychologist 

My favorite part of being a psychologist is helping kids, teens, parents, and young adults understand themselves better through comprehensive testing evaluations. I believe that accurate identification of symptoms, diagnoses, and treatment options is something all people deserve and have dedicated my career to providing high-quality neurodevelopmental, psychoeducational, and behavioral/emotional health assessment services. I have been an evaluator and therapist working with people aged 3 to 25 and their families since 2014. My treatment approach uses developmentally informed and whole-family interventions that are research-informed, personalized, and practical.
