- Lynn and Ron Penner-Ash were the driving forces behind the design of Penner-Ash Winery. They had a very specific vision of the winery's location, siting and usability.
O'Brien worked very closely with the Penner-Ashes and Waterleaf Architecture to make sure that every aspect of the project satisfied the desires of the Owners while meeting and surpassing
design and construction standards. The end result was a perfectly situated hilltop winery.
