SIGMA Actuarial appoints Guttman as consultant

SIGMA Actuarial Consulting Group appoints Jeff Guttman as an actuarial consultant, based in the Nashville metropolitan area on a hybrid basis.

Guttman joins from HUB International, where he spent nearly seven years as director of client analytics. He has also served as president and CEO of risk management consultancy JiGSAW Risk Specialists since October 2018, a role he continues to hold.

He brings close to three decades of risk and insurance consulting experience to the position. Before HUB International, Guttman spent more than 12 years as a senior risk consultant at Willis Towers Watson, working on risk quantification and risk optimisation tools across property and casualty, professional liability, management liability and enterprise risks.

Earlier in his career, he spent nearly nine years as a senior risk analyst at Marsh in San Francisco and New York, with a focus on mass tort, integrated risk and alternative risk transfer.

SIGMA says Guttman has built deep expertise in integrating data analytics and risk management consulting, working with clients to turn complex data into risk strategies. He has known Al Rhodes of SIGMA for 38 years, going back to their time at Corroon & Black.

SIGMA describes itself as an actuarial firm whose services support brokers, risk managers, CFOs, auditors, captive managers, regulators, public entities, self-insured groups and insurance carriers.
