SE2 is bidding farewell, at least formally, to co-founder Eric Sondermann, who plans to focus on his other varied interests including “further civic leadership, more writing and commentary, some high-level consulting, perhaps even something entrepreneurial, as well as time on his bicycle.” Sondermann will continue to collaborate with SE2 “on current and future projects, ensuring continuity for existing clients.”
The firm says that remaining co-founders Eric Anderson and Susan Morrisey will share SE2 ownership and split leadership responsibilities.
