Since 1991, Catholic Leadership Institute has been equipping and emboldening leaders in the Catholic Church, continually evaluating needs, providing resources with a discipline to offer solutions, speaking with the heart of the Church, and setting the stage for meaningful, intentional conversation. This Case Study library seeks to share and explore the principles, challenges, and successes that led to successful leadership initiatives in the Church, shedding light on inspiring individuals, parishes, and dioceses so that others might learn and repeat successes in the Church today.
