Abstract Perfectionism can result in negative consequences for those who set unattainable goals and repeatedly strive to achieve high standards. Relying on inflexible behaviors and building one's self‐worth around success can become problematic and affect performance, interpersonal relationships, and cause mental distress. In the current case illustration, perfectionism's negative implications are depicted through a client named Sara, a stressed‐out junior physician who just graduated from medical school. Struggling with issues related to self‐worth, depression, worry, independence, and interpersonal difficulties, Sara underwent cognitive behavior therapy during 15 sessions. The case illustration shows how an individualized conceptualization of perfectionism can be made and what is important to target in treatment, such as preventing the need for repeated checking, conducting surveys to refute dysfunctional beliefs, and introducing activities that are unrelated to accomplishments. Current research on the efficacy of treating perfectionism is also summarized and interventions particularly relevant for clinical practice are presented.
