Tony Ryan, chief administrative officer at Fidelity Investments, has left the firm.
Mr. Ryan, who left “in recent weeks,” will be replaced by various executives at the firm, company spokesman Vincent Loporchio said. He had reported to Ronald O'Hanley, who took over as president of asset management in May.

Separately, Jack Callahan, executive vice president of sales for Fidelity Workplace Investing, is retiring at the end of the month after 19 years at the firm, said Mr. Loporchio..
Steve Patterson, head of relationship management in workplace investing, will replace Mr. Callahan.
