Della S. Lusk, Ph.D.

With over 25 years of clinical experience, Dr. Della S. Lusk is a Licensed Psychologist dedicated to helping clients navigate life’s complex challenges, overcome obstacles, and achieve their personal and professional goals. Dr. Lusk provides a warm, compassionate, and evidence-based therapeutic environment where individuals, couples, and families feel genuinely supported and empowered to thrive. Dr. Lusk’s therapy practice spans across the entire lifespan, offering specialized care for children, adolescents, college students, and adults. She places a strong emphasis on helping young people navigate the critical transition into independence and "adulting"—from managing academic pressure and career decisions to building self-confidence, emotional resilience, and healthy boundaries. In addition to individual psychotherapy, Dr. Lusk works closely with couples and families to improve communication, resolve long-standing conflict, and restore emotional connection within the home. Beyond psychotherapy, Dr. Lusk possesses deep expertise in comprehensive psychological and neuropsychological evaluations. She specializes in testing for ADHD, Autism Spectrum Disorders, and Learning Disabilities, providing clear diagnostic clarity and actionable recommendations. Her evaluations frequently assist students and professionals in securing necessary academic and testing accommodations (such as 504 plans, IEPs, and standardized testing modifications for college and graduate programs) as well as workplace supports. As a recognized qualified expert witness in the State of Arizona, Dr. Lusk also conducts thorough evaluations for forensic, educational, employment, and complex clinical diagnostic purposes.
