Dr. Katherine Corteselli is a Staff Psychologist at the Center for Effective Therapy. She earned her B.A. in Applied Psychology and Human Development from Boston College and received her Ph.D. in Clinical Psychology from Harvard University. She completed her pre- and postdoctoral fellowships at the Baker Center for Children and Families, where she gained specialized training in evidence-based interventions for youth and families.

Dr. Corteselli has extensive experience working with children, adolescents, and families, treating a range of mental health challenges. She is trained in several evidence-based models, including Cognitive Behavioral Therapy (CBT), the Modular Approach to Treatment for Children with Anxiety, Depression, Trauma, or Conduct Problems (MATCH-ADTC), Parent-Child Interaction Therapy (PCIT), Trauma-Focused Cognitive Behavioral Therapy (TF-CBT), and Exposure and Response Prevention (ERP). Beyond direct clinical work, she collaborates with multidisciplinary teams to support families in navigating complex systems of care, including school consultation. She brings humor, curiosity, and a strengths-based approach to treatment, empowering young people and their families to take an active role in therapy, develop insight, and build lasting coping and problem-solving skills.

Committed to expanding access to high-quality mental health care, Dr. Corteselli is actively involved in training, consultation, and implementation support for community mental health agencies as part of The Baker Center's Quality Care Initiative. Her research focuses on increasing access to empirically supported and contextually adapted mental health interventions for historically underserved communities.
