“MoFo” … Seriously?

In the 1970s, when teletype was used to send overseas cables, the firm purposely chose “mofo” as our teletype address. The nickname stuck, and we later decided to use it as our web address. In many ways, the MoFo nickname is an affectionate reminder that while we are very serious about our clients’ work, we don’t take ourselves too seriously.
