How It All Got Started

Father Mike Boyle“In 1978 when I was a priest at St Vincent’s Parish in Phoenix, AZ, our parish secretary kept all her information on index cards—hundreds and hundreds of index cards. I knew there had to be a better way to track the information critical to the unique needs of the Catholic Church. I assembled a small team with knowledge of parochial administration, church office procedures, church administration, and computer programming. My goal was to create a system that allowed us to spend less time recording information and more time using that information to minister to our parishioners. Other parishes agreed, and so we grew.”

— Father Mike

Continuing Our Legacy of Innovation

Over 40 years later, Parish Data System is still listening to our church partners and we are still making it our mission to find a better way to help them serve their parish and parishioners. With PDS and Realm we have two solutions that will allow you to spend more time ministering. In many ways, it feels like we’re just getting started.


’70s – Good times. Dy-no-mite!

ACST - 1970 DecadeParish Data System™ (PDS) was founded in 1978 by Father Michael Boyle, Roseanne Trombley, and Joseph Gordon to meet the real-world needs of the Church.



’80s — Were like, totally rad.

1980'sThese were our DOS days. PDS expanded rapidly from just the original PDS Census/Contribution program. PDS Journal, PDS Facility Scheduler, PDS Ledger/Payables, and PDS Foccus programs were released.



’90s — Aced it. Alrightyyyy then.

ACST - 1990 DecadePDS continued to expand its product lineup introducing PDS Religious Education, PDS School Management, PDS Grade Book, and PDS Payroll. We also began the transition from DOS to Windows when PDS Census/Contributions Version 17 was released for both MS-DOS and Windows. Our first diocese product was released, called PDS Link.



’00s — We all survived Y2K.

ACST - 2000 DecadeWhat a decade for innovation! Starting in 2000, PDS Church Office, PDS Formation Office, and PDS School Office were released for Windows and could share the same database between them. In 2004, ACS Technologies® purchased Parish Data System keeping it as a separate brand and continuing its development. For example, we introduced a couple new diocesan solutions: PDS DioOffice and PDS DioView. We also made the move from installed software to our PDS OnDemand solution.



’10s — Because YOLO.

ACST - 2010 DecadeRealm® was born! And after a few years in development, we began marketing Realm to Catholic parishes and dioceses. (It’s our fully web-based parish management option.) Plus, we added a couple new product initiatives for Catholic dioceses: Realm Network and Realm Office. Of course, we also continued to enhance our core PDS solution with the release of PDS Version 9.



’20s — Just gettin’ started…

Timeline 2020We couldn’t be more excited about where things are headed. We’ve entered this new decade with a few recent acquisitions, and we are rapidly working on integrating everything into our single-system approach. Specifically, we are really excited about two new solutions. MissionInsite™ gives churches tremendous information and insight into their communities, and MinistrySmart™ teaches parish staff how to make the most of their ministry. In July 2020, we released PDS Version 10 which provides parishes with better accessibility, performance, and security in PDS.  Of course, we continue to do our bi-weekly updates to Realm as well.
