A Westport resident is among three recently appointed members of the Fairfield University Board of Trustees.

Andrew J. McMahon, senior executive vice president for AXA Equitable Life Insurance Co. and president of its financial protection and wealth management business, was named a trustee in October.

He and the two other new trustees are alumni of the school.

The other new trustees are Katherine N. Lapp, the executive vice president of Harvard University, and Sheila K. Davidson, executive vice president in charge of law and corporate administration for New York Life.

McMahon also is a member of AXA Equitable Life's executive operating committee. He joined AXA Equitable in March 2005 as senior vice president to launch the company's Strategic Initiatives Group. Later that year, he was promoted to executive vice president and was named chief operating officer of AXA Advisors. McMahon was named chairman of AXA Advisors in 2007.

Before joining AXA Equitable, he was a principal at McKinsey & Co., and served as a life insurance practice leader in North America. Prior to McKinsey, McMahon spent several years in management positions with various business divisions of General Electric.

McMahon, of New York City, earned a bachelor of science degree in computer science from Fairfield University in 1989 and a master's degree in business administration from Columbia Business School in 1995.

Lapp, who lives in Cambridge, Mass., joined Harvard's Office of the President and Provost as executive vice president in October 2009. As executive vice president, she is the chief administrative officer for the university and a member of the president's senior management team.

Prior to her appointment at Harvard, Lapp served as executive vice president for business operations for the University of California. She also was executive director and chief executive officer for the New York Metropolitan Transportation Authority for five years until 2006, where she was responsible for the operations, finances and long-term business strategies. Before joining the MTA, Lapp worked in the legal field, serving as New York State director of criminal justice and commissioner of the Criminal Justice Services Department from 1997-2001; as New York City's criminal justice coordinator from 1994-97; and as chief of staff and special counsel to the New York City deputy mayor for public safety from 1990-93.

Born in Cedarhurst, N.Y., Lapp received a bachelor of arts degree in history from Fairfield University in 1978 and a law degree from Hofstra University in 1981.

Davidson joined New York Life 19 years ago after several years with the National Association of Securities Dealers. Following a number of positions within the Office of the General Counsel, she was appointed the company's general counsel in 2000. She now is the executive vice president in charge of law and corporate administration. She is also a member of the company's executive management committee.

Davidson graduated cum laude from Fairfield University in 1983 with a bachelor of arts degree in political science. She earned her law degree from George Washington University in 1986.
