Few people know the communications sector better than Bill Berkman, co-managing partner at Associated Partners, LP. He has helped to pioneer some of its technology, for one—he is credited on more than 20 patents. But it is Bill’s investing that truly sets him apart. He offers a steady hand in a sector characterized by rapid technological change and volatility, and has realized tremendous value during his 25-year career by concentrating on a portfolio of longer-term investments in the industry, including cable, wireless, and communications infrastructure such as fiber and towers. Working with his brother David across two public companies and various private partnerships, they have turned multi-million dollar stakes in a variety of communications businesses into multi-billion dollar scale for his family and their investors.
