Dr. Cassandra McDonnell, Ph.D., Licensed Clinical Psychologist

Cassie McDonnellI am a licensed clinical psychologist, and provide counseling and psychological assessment services to school-aged children, adolescents, and adults. I am originally from the Northern Virginia area, and received my Bachelor of Science in psychology from The College of William and Mary. I then went on to obtain Master and Doctoral degrees at University of Missouri St. Louis with specializations in Behavioral Medicine and Child Psychology. I completed my post-doctoral training at University of Virginia, and have been practicing within Loudoun County ever since. I have provided psychological services in residential, inpatient, community clinics, schools, and integrated primary care settings. I first learned about Youth for Tomorrow through my work with local teenagers and their families, and was excited to join the organization in July 2018, adding outpatient psychological assessment to their wide range of behavioral services.

Clinically, I work with a wide variety of presenting issues and concerns. My specific areas of specialization include anxiety disorders, posttraumatic stress, grief and loss, and behavioral medicine concerns (such as chronic pain, insomnia, and behavioral adjustment to chronic/major medical conditions). I have additional specialization and certification in working with children and adolescents with sexual reactivity and/or sexually abusive behaviors. In counseling, I utilize an integrative cognitive-behavioral approach that incorporates acceptance, mindfulness, and values work. I am passionate about working collaboratively with individuals and families to apply evidence based treatment concepts within the context of uniquely personal patient needs and goals.
