The goal of the Senior Leadership Team (SLT) is to establish and implement the vision of the parish. It is a group made up of the pastor and associate pastor, operations director and selected members of the parish staff and dedicated leaders in parish ministries whom the pastor has invited. Our goal is to organize the administration of the parish in a new way, so as to effectively minister to the people of the parish in the environment of a newly–united parish and fewer priests. We intend to develop leadership within the parish so as to place less administrative demands on the priests and enable them to do the primary job of shepherding for which they were ordained. Precisely because there are challenges and obstacles in the process of transition, the goal of the SLT is to implement a vision that seeks to recognize those difficulties and build the new reality that can use those challenges as a means of growth and transformation, just as the cross is the point of transformation from death into new life.

The purpose of the SLT is to set a vision for the parish and ensure that this “big–picture” vision is made reality by breaking it into details and leading the parish in the process of implementing that vision. Currently, our major goals are to help unify our parish while respecting the traditions that our parishioners have from their previous parishes and to improve regular communication to the entire parish. This team is distinct from the Parish Pastoral Council in that, while the pastoral council seeks to get feedback from our parish and advise the pastor and staff, the SLT is a decision–making body that looks forward and, from the advice of the parish council, seeks to implement a vision with the pastor. The mission, composition, and authority of the SLT can be changed by the pastor depending on the needs of the pastor or the parish.
