Dr. Kmack utilizes Cognitive Behavioral Therapy (CBT) and incorporates techniques from other evidence-based treatments to help her clients foster insight and develop adaptive strategies. She tailors her approach to highlight the strengths and meet the needs of each individual client. In addition to her work at Wavelengths, Dr. Kmack is a school psychologist, and enjoys helping clients and families navigate the special education system.
