Here is their main website page:

Summary:
"Wimberley is a father-son partnership dedicated to the design and manufacture of professional photography equipment. We make tripod heads for large telephoto lenses, macro accessories, Modular Flash Brackets, Arca-Swiss style quick-release clamps & plates, and more..."
I am relatively new to this information, so I will do my best as to what I am allowed to disclose: the Wimberly Professional Service membership is offered to photographers that fit certain criteria for Wimberley. I don't believe they advertise benefit, since (AFAIK) they invite the photographers into their program. You are given additional benefits over the standard ones for regular customers, plus many more things. For example, they allow you to test out new/used equipment for longer periods, etc. at no charge. That is only a small part of the Professional Service membership. They tend to supply equipment for photographers that tend to do more nature/outdoor related photography, but it is not exclusive to that group. The quality of their products (in my experience so far) is excellent, no question.
Hope that helps?

Marc
