Sidney DiDomenico is a strategic leader in public-sector risk pooling and employee benefits innovation, with more than three decades of experience across the insurance spectrum. Her career spans property and casualty administration, self-funded program development, and large-scale pooled purchasing strategy — culminating in leadership at one of the nation’s largest Joint Powers Authorities.

Sidney’s work is grounded in a clear belief: public agencies deserve sophisticated, data-driven employee benefits solutions that are fiscally sound, transparent, and built for long-term sustainability.

At PRISM, Sidney plays a key role in shaping the next generation of public-sector health pooling — guiding strategic initiatives, reserve and funding alignment, program expansion, and vendor innovation. Known for her collaborative and purpose-driven leadership style, Sidney builds high-trust relationships grounded in transparency, shared knowledge, and open communication. She views risk pools not simply as insurance mechanisms, but as strategic platforms for stability, growth, and public-sector resilience.
