Justworks Expands Risk & Insurance Programs With Two New Senior Leaders to Build on Continued Growth

Genesis Dunn to lead Risk Programs as Vice President and Gus Koumbaros joins Justworks as Vice President of Health Insurance Underwriting

NEW YORK — February 3, 2021 - Justworks, the nation’s fastest-growing HR technology company, will expand its Risk and Insurance programs with the creation of two new Vice President roles. Genesis Dunn, previously Director of Workers’ Compensation, will assume the role of Vice President of Risk Programs and Gus Koumbaros, who joins Justworks from United Healthcare, will serve as Vice President of Health Insurance Underwriting.

The move aims to unlock and focus existing expertise within the organization, as well as to lay a foundation for further specialized hiring on both teams in the coming months. Together, Dunn and Koumbaros will expand Justworks’ health insurance and non-medical risk programs to accommodate the company’s continued growth, with a focus on data and automation. Investing to further expand these specialized teams comes at a time when Justworks’ increasingly flexible insurance offerings have allowed the company to gain a foothold in new verticals and markets across the country.

“In order to capitalize on the growth opportunity ahead of us and deliver next-generation products to our customers, I am excited to strengthen our team with these two capable leaders,” said David Feinberg, Vice President of Insurance and Risk Programs at Justworks. “Genesis and Gus will play a key role in further developing our carrier and other partner relationships, improving our overall workflow, and delivering a benefits experience that our customers love."

In her new role as Vice President, Dunn will concentrate on revenue and risk-bearing lines of the business by overseeing Justworks non-medical risk programs, including workers’ compensation and state unemployment insurance. Dunn joined Justworks in 2017 as the Director of Workers’ Compensation. In this role she also focused on building relationships with Justworks newest insurance carriers at the time, United Healthcare and Kaiser Permanente. Dunn brings over a decade of experience, prior to joining Justworks, during which she held workers’ compensation and underwriting positions at Preferred Employers Group and Everest Insurance.

As Vice President of Health Insurance Underwriting, Koumbaros will lead Justworks’ underwriting team and manage the new business and renewal aspects of insurance. Koumbaros joins with over three decades of experience within the healthcare industry. He started his career at Aetna and later moved to Oxford Health where he held a leadership role focused on underwriting small and large group employer-sponsored health insurance. Most recently, he worked for UnitedHealthcare as VP of Underwriting for the Central Region, managing $12+ billion of premium for the region.
