Human Resources: MassMutual Names Ian Sheridan and Eric Wietsma Corporate Vice Presidents

SPRINGFIELD, Mass., Sept. 7 /PRNewswire/ -- MassMutual Financial Group has
promoted two key members of its Retirement Services Division's management team
to corporate vice president: Ian Sheridan and Eric Weitsma.

Ian Sheridan, chief marketing officer for MassMutual's Retirement Services
Division, joined MassMutual as vice president of marketing in 2003. His
visionary approach to retirement plan participant education began with the
creation and implementation of MassMutual's e4(SM) Electronic Enhanced
Enrollment Experience. The patent-pending e4 technology is the industry's
first-ever wireless participant education and enrollment system and was named
the "#1 Wireless Innovation" for 2006 by InformationWeek magazine. Since its
inception, e4 has consistently achieved participant action rates averaging 90%
and participant savings rates 3% above the industry average. As a leading
advocate of applying principles of behavioral finance for the development of
more effective education materials, Sheridan and his organization have
successfully leveraged MassMutual's CRM analytics technology to design
targeted, behavior-based education campaigns that have resulted in double
digit increases in participant savings activity.

As chief marketing officer for Retirement Services, Sheridan has direct
oversight of the value proposition, product innovation, and development of all
IRA, defined contribution, defined benefit and investment products. Prior to
joining MassMutual, Sheridan served as head of marketing and business
development for ADP Retirement Services.

As corporate vice president of Investment Services, Eric Wietsma heads up
the investments organization of MassMutual's Retirement Services Division
encompassing strategy, research, investment product development, investment
reporting, and treasury operations. Wietsma formed MassMutual's Investment
Consulting Team to provide additional investment support to clients,
prospects, and distribution channel relationships. His team recently
implemented MassMutual's Smart Architecture(SM) Investment Program, an
aggressive expansion to more than 140 investment options and more than 60 firm
relationships. Wietsma and his organization were key contributors to the
development of a new third-party investment certification program and
MassMutual's Fiduciary Warranty, both of which will be rolled out in the
fourth quarter. The Fiduciary Warranty will help provide retirement advisors
with assurance that an additional level of screening supports their evaluation
of overall investment lineups, and offers increased confidence to advisors and
plan sponsors alike.

Prior to joining MassMutual in December 2005, Wietsma managed the public
retirement plan business at The Hartford. He is a member of the American
Academy of Actuaries and holds his Series 6 and 26 FINRA licenses.

"The retirement industry continues to evolve rapidly and providers like
MassMutual must anticipate and respond to the needs of retirement plan
advisors, sponsors and participants just as rapidly," said Fred Castellani,
executive vice president of MassMutual's Retirement Services Division. "Our
customers have benefited from the vision and commitment demonstrated by both
of these exceptional leaders," he adds.
