Prior to starting Colva Insurance Services, Rajiv worked in the Risk Finance Department of Chartis helping to manage and evaluate the risks of a $4 billion dollar alternative asset portfolio of life insurance policies with $18 billion in death benefit. While there he developed Chartis’ Reverse Engineering capabilities designed to save policyowners millions of dollars in unnecessary premium payments on life insurance policies while maximizing their expected death benefit proceeds. He also provided valuable analysis that helped shape Chartis’ view of mortality on these policies. Prior to working at Chartis, he worked in the Pricing and Mortality Departments of New York Life where he helped with the pricing, design, system illustration, and profitability analysis of New York Life’s Universal Life and Variable Universal Life products as well as conducting analysis and review of New York Life’s mortality experience.

Rajiv holds a B.S. from Stanford University. Prior to beginning his corporate actuarial career, he was a teacher in high-needs schools in New York City. He started Colva as a means to educate policyowners about both the risks and benefits of investing in life insurance and help them get the most value out of their policy. His outside interests include basketball, poetry, and serving on the leadership committee of Glassless Minds, a pending 501c3 non-profit that fosters constructive emotional outlets and personal expression forums for troubled teenagers and young adults through a variety of creative arts.
