The mission of The Vadis Project is to equip the Catholic Church in America with practical strategies that will help her fulfill the Great Commission (Mt 28:19-20) and revitalize the Church.


Since the late 1960s Christianity has declined significantly in the United States and Catholicism is no exception to this trend. It is well known now that members continue to leave and most parishes are struggling. The number of priests has declined from 52,154 to 37,181 and over 2500 parishes have closed. If we do not respond to this crisis then the Church in the U.S. will continue it's steady decline. 


Despite these disheartening numbers the Lord continues to work and bless His Church in many ways. In particular, specific dioceses and parishes continue to grow and flourish in the face of many challenges. At The Vadis Project we are studying the people, programs, parishes, and dioceses that are the most fruitful. Then we are sharing the strategies and practices that are the best with the whole Church so that Catholicism is every U.S. community can have a better chance to thrive.


Our research allows us to provide parishes and dioceses with the best information, which in turns allows them to make the best decisions. We work with the Church and help develop orthodox and innovative solutions to the problems she is facing. The work being done at The Vadis Project is equipping the Church with research-based solutions to the greatest challenges encountered today.

David Demboski is the founder of The Vadis Project and he operates it with his wife, Stephanie, out of Pittsburgh, Pennsylvania. Feeling called by God to help revitalize the Catholic Church in the U.S. in a radical way, they started this organization as a means to equip dioceses and parishes with vital information and resources needed to reignite the flame of Christ's love in their members. 

David holds a B.A. in Theology and Philosophy from Benedictine College and an M.A.  in Sacred Scripture from the Augustine Institute. He is in the final stages of his PhD work at Duquesne University.
