Heritage Alliance – a regional effort to identify groups and promote their cooperation in the name of historic knowledge and preservation
 Special thanks are extended to:
- Washington County History & Landmarks Foundation for compiling the information herein contained, and Sandy Mansmann who edited the guide.
- Beaver County Historical Research & Landmarks Foundation, and especially Brenda Applegate, for inspiration and gracious assistance with this project.
- Washington County Tourism Promotion Agency for the generous funding to bring this guide book to publication.
- Washington County Planning Commission for providing the pertinent map for our region.
- The organizations that have participated and shared their information.
We have attempted to include well-known and lesser-known heritage organizations in Washington and Greene counties, as well as some others who are significantly linked to our region or that requested to be included. Unfortunately, despite our effort to contact groups, some had not responded by the publishing deadline.
We hope that this information can be expanded in future communications.
