About Heather Gallagher, Ph.D.

Dr. Gallagher received her Bachelor of Arts in Psychology from Smith College and her masters and doctoral degrees in clinical psychology from the University of Southern Mississippi. She completed an APA approved predoctoral internship at Children's National Medical Center in Washington, DC, followed by a postdoctoral fellowship in pediatric psychology at The Cleveland Clinic in Cleveland, OH. During the course of her training, Dr. Gallagher has worked with children and adolescents in both inpatient and outpatient clinical settings. She has also worked extensively in pediatric medical settings with children suffering from a broad range of medical conditions.

Dr. Gallagher joined the Counseling Center in 2001 and is licensed to practice in the state of New Hampshire. She specializes in therapy with children and their families. She currently works primarily with children under 12 years of age. Dr. Gallagher particularly enjoys working with children suffering from anxiety, as well as those with ADHD and Autism Spectrum Disorders. She also enjoys working with children adjusting to acute and chronic medical conditions.

Dr. Gallagher specializes in cognitive behavioral therapy, but takes the developmental level of the child into account in planning appropriate interventions. She frequently utilizes play with young children to help increase their comfort level. Dr. Gallagher most often works with both children and their parents, and strongly believes in coaching parents to utilize cognitive and behavioral techniques with their children outside of the therapy session. She routinely works with parents around managing childhood behavioral issues, and also consults regularly with teachers and guidance counselors to enhance a child's functioning in school.
