(Pinnacle), a leading property and casualty actuarial consulting firm, today announced Principal Roosevelt Mosley will become the firm’s new managing principal effective April 9. Outgoing Managing Principal Joe Herbers will return to his role as firm principal.

“Over the last two decades, Pinnacle has grown into the leading independent property and casualty actuarial consulting firm in the U.S.,” Mosley said. “Our position in the industry has been largely due to the successful execution of our established business strategy. Collaborating with the firm’s principals, Joe has done an exceptional job of driving that strategy and helping to build Pinnacle’s widening reputation for quality, accuracy and innovation.”

The managing principal plays an important and highly collaborative role at Pinnacle and works with Pinnacle’s principals to set strategy and determine organizational goals. The managing principal also coordinates the implementation of policies and procedures, monitors day-to-day business operations and supports oversight of the firm’s functional areas. The role is also essential to communicating to all key stakeholders, including clients, on all important matters.

“The word growth does not appear in Pinnacle’s strategic plan, as set by the firm’s principals,” Herbers said. “Instead, our plan is focused on our commitment to our clients, empathetic customer service and outstanding communications. Those pillars have played a key role in Pinnacle’s success and are values to which Roosevelt has dedicated his career. He is particularly well-qualified for this role and will excel in growing and developing Pinnacle’s prominence and eminence in the property and casualty industry.”

Mosley has over 30 years of experience in the insurance industry and has worked for Pinnacle since 1999. He has been a principal at Pinnacle since 2006 and has led several of the firm’s functions including IT and strategic partnerships. Mosley’s practice is focused on predictive analytics and he is very widely known and respected for his leadership in the property and casualty industry.

He has been heavily involved in the profession and has volunteered with a number of important professional organizations. He is currently the immediate past president of the Casualty Actuarial Society (CAS) and served as president of the organization from 2022 to 2023. He has also volunteered with many industry organizations over the years, including the CAS, the American Academy of Actuaries, the Actuarial Foundation and the International Association of Black Actuaries (IABA).

Herbers has served as Pinnacle’s managing principal for almost 16 years. He is one of the firm’s founding principals and has worked to advance the actuarial profession. He is a sought-after speaker and is the author of numerous thought leadership pieces on actuarial matters. In addition to his long track record of serving hundreds of clients, he has dedicated himself to developing Pinnacle’s culture, and its scores of talented professionals.

He will continue to work at Pinnacle as a principal and consulting actuary, focusing on employee development and management of a designated functional department, or key management area (KMA).

“On behalf of all the firm’s principals, I thank Joe for his many years of service as Pinnacle’s managing principal. I am looking forward to continuing his legacy as managing principal,” Mosley added.
