Andrew Hanlon has been appointed sales director for Springfield-based MassMutual’s retirement services sales and client management organization.

Hanlon, who is based in Boston, recently served as a key account manager in MassMutual’s distribution support organization. Before joining MassMutual in 2006, Hanlon spent 10 years with Putnam Investments where he held positions in operations, implementation and sales.

"Our retirement services business is experiencing exceptional growth," said Hugh O’Toole, senior vice president of sales and client management for MassMutual’s retirement services division. "The addition of [Hanlon] to our already robust team is evidence of MassMutual’s serious commitment to serving advisors and third-party administrators with a strong focus on retirement plans with under $5 million in assets."
