We have our culture quite well defined by our Four C's - Create, Communicate, Care and Curiosity

From the definitions in Organizational Culture (Part II): Meta Process I reckon you've created a warm nurturing Clan culture (Collaborate) ... so using your fuller definition (which I really like BTW):

we Create, we Communicate, we Care about our Clients and Colleagues and we do everything with Curiosity

I make that Eight C's! Sorry, couldn't resist. :)
