Kristen Mangum, PhD.

Dr. Kristin Mangum is a licensed psychologist with 15 years of clinical experience treating individuals, couples, and families in inpatient and outpatient clinical settings. She earned her doctorate in clinical psychology from the University of Missouri St.Louis and then completed specialized post-doctoral training in the treatment of eating disorders at the Center for Eating Disorders (CED) at Sheppard Enoch Pratt hospital in Maryland. She has served as staff psychologist in outpatient practices, provided telehealth therapy services for an online medical group, and functioned as Director of Psychology at an outpatient eating disorder treatment center. She has extensive training and experience in the treatment of eating disorders and body image issues, as well as anxiety, depression, self-esteem, stress management, and problems in interpersonal functioning. Dr. Mangum approaches therapy with compassion and optimism. She strongly believes that everyone has the ability to change, and that change occurs through a balance of compassionate acceptance and action.  Her treatment philosophy is “individuals are stuck- not broken,” and she believes counseling is about helping individuals become “unstuck” — from unhelpful ways of thinking, unhelpful patterns of behavior, and unhelpful ways of approaching problems. She does this through an integration of therapeutic approaches — Acceptance and Commitment Therapy (ACT), Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), mindfulness, and interpersonal based approaches. Ultimately, the approach chosen depends upon the individual and their unique treatment needs.
