The Hollyleaf
In 2004 we relocated our offices to a 250 year old historic building located in Wrightstown, Pa. 

The building, named "The Hollyleaf" due in part to the large holly trees on the property as well as a bed and breakfast after the same name.  We have rehabbed the existing structure with improvements to help extend its life to the foreseeable future.  We consider ourselves caretakers of this historic building rather than the owner.
