Our Team

Dr. Holly Clausen, Ph.D., L.P.

Dr. Holly Clausen is a pediatric neuropsychologist who began seeing patients in the St. Cloud area in 1996. She initially worked at St. Cloud Hospital and continues a professional association with the hospital. Dr. Clausen quickly gained a reputation for providing extremely thorough, thoughtful evaluations of children and adolescents, as well as being able to provide results to families, schools and professionals in a comprehensible and practical manner. Licensed by the state of Minnesota, Dr. Clausen has been in private practice since 2001 and in January 2010 opened a new clinic, Developmental Diagnostics, LLC. The new clinic has an exclusively pediatric population, although some young adults with developmental disorders are evaluated as well. Dr. Clausen has bachelor’s degrees in psychology and music from Jamestown College in Jamestown, North Dakota. She completed her master’s and doctoral degrees in a dual degree program specializing in clinical and developmental psychology at the University of Illinois at Chicago. During her graduate training, Dr. Clausen did research and specialized training in the development of brain functioning. She also completed specialized clinical practica placements in pediatric and adult neuropsychology. She completed an internship and served as a postdoctoral fellow at the University of Minnesota Division of Pediatric Neurology.

Dr. Clausen provides thorough, neuropsychological and neurodevelopmental assessments of children of all ages from infancy through early adulthood. She also provides assessment services to adults with developmental disabilities such as Down’s Syndrome or other genetic or developmental disorders. Children who can benefit from this type of assessment include those with traumatic brain injury, seizure disorders, genetic disorders, chronic medical conditions, developmental delays, attention, learning and behavior problems, as well as children who present complex psychological, medical and behavioral profiles. Assessment of the impact of psychological, emotional and social issues upon a child’s functioning is also an important component of the neuropsychological evaluations completed by Dr. Clausen.

Dr. Clausen has considerable experience in teaching and public speaking. Seminars she has presented include Mild Traumatic Brain Injury in Children, Neurodevelopment Disorders (including Tourette’s Syndrome, Obsessive Compulsive Disorder and Attention Deficit Hyperactivity Disorder), Fetal Alcohol Syndrome, Seizure Disorders in Children, and various topics on ADHD and managing difficult behavioral or emotional problems. She has provided professional supervision for psychology interns as part of an accredited internship program, and has also served as a private supervisor. Dr. Clausen also taught Introductory Psychology and Developmental Psychology to undergraduates as an Adjunct Professor at the College of St. Benedict in St. Joseph.

Recently, Dr. Clausen developed a conflict resolution program for grade school classrooms designed to help groups of children (who were experiencing interpersonal problems and bullying issues) learn how to manage and resolve conflict in ways that are productive and assertive. Dr. Clausen worked directly with children in the classroom to help resolve long-standing communication and interpersonal conflicts. Dr. Clausen has also completed training in mindfulness techniques and has added this component to her practice through teaching mindfulness strategies to parents and children as a way to decrease stress and anxiety levels.

As the Psychometrist for Developmental Diagnostics, Sam is responsible for the administering and scoring of psychological and neuropsychological tests given to children coming to us for evaluation.

Making a connection and maintaining a good relationship with the children is a necessary skill Sam brings to the office, ensuring that each child is as comfortable and relaxed as possible.
