Presenter: Dr. Lisa Hosack, Assistant Dean, Professor of Social Work, Grove City College

Description: Anxiety goes hand-in-hand with leadership. And at low levels, it’s a productive companion, leading to conscientiousness and focus. Yet often, leaders experience a level of anxiety — tethered to perfectionistic self-expectations — that paralyzes versus motivates. This workshop will explore the origins of maladaptive perfectionism and practical ways to cultivate the peace of Christ within.
