Mike Szot will be primarily responsible for serving clients and ensuring effective production. During his 30-year career in the insurance brokerage industry, Szot has developed creative risk solutions including the design and implementation of the first major homebuilder rolling wrap-up program, which is still in existence today. Szot is a current leadership board member of the University of California Lusk Center–Real Estate, a board member of The Beavers and an active member in the residential Business Industry Association.

George Dale will provide strategic direction and oversee Aon’s residential services across the U.S., London and Bermuda.
