Benjamin E. Allen has been promoted to chief executive officer of Parnassus Investments, effective today. In this new role, Mr. Allen is responsible for the overall direction of the firm’s investment and business operations. He has been president since January 2017.

Mr. Allen joined Parnassus in 2005 as a senior research analyst after serving in the firm’s internship program. He demonstrated outstanding leadership capability and has assumed positions with increasing responsibilities over the past 13 years. He was promoted to director of research in 2008 and portfolio manager of the Parnassus Core Equity Fund—the firm’s largest fund—in 2012. He has also managed the firm’s client relationship, sales and marketing functions for nearly a decade.

Mr. Allen said, "I'm honored to carry forward the tradition and culture of Parnassus Investments, and will do my best to deliver Principles and Performance® to our investors. [Founder] Jerry Dodson has been an important mentor for me, and I’m pleased that he will continue his diligent work for our firm and its investors in his new role. I look forward to continuing to develop our research-oriented culture and our service to our investors as CEO and portfolio manager of the Parnassus Core Equity Fund."

Mr. Dodson added, "I'm pleased that Ben will lead our firm and carry forward the rich heritage of Parnassus. When I decided to test my belief that we could deliver strong investment returns and not compromise our values over 30 years ago, I never dreamed that Parnassus would become the largest ESG mutual fund company in America. Ben has helped me steer Parnassus for a long time, and I trust him. The firm is in excellent hands with Ben as we begin our next chapter of delivering Principles and Performance to our investors."
