Dave De Graffenreid Second VP

My wife Donna and I saw our first GMC Coach across the street from one of our gardening accounts. The owners were friendly and gave us a tour. They also invited us to stop by a local Pacific Cruisers Rally in Huntington Beach to see other coaches. Boy, did we meet the experts! We bought our Palm Beach a few weeks later Mesa Arizona. That was January 1992
My passion has always been growing plants. During and after my education to become an industrial arts teacher I supported my self landscaping and gardening. Donna joined me in the business that allowed us to travel in the winters. We drove the Palm Beach to many palm beaches throughout Mexico.
