Rosenberg & Parker Expands Leadership with New Partners

On July 9, 2025, Rosenberg & Parker, the largest independent surety-only brokerage in the globe, announced the addition of three high-profile partners as part of its ongoing growth strategy. The new partners include Jack Rosenberg, President of the firm; Harry G. Rosenberg, Leader of the Financial Sponsors Practice; and James DiSciullo, Director of Advisory Productions and Leader of the Energy Practice. This strategic move solidifies the firm's independence within a rapidly evolving market.

A Vision for Growth

Matt Rosenberg, CEO, expressed his excitement about the new appointments, stating, "We are incredibly proud to have Jack, Harry, and James join us in partnership." The firm has experienced remarkable growth since they started their journeys with Rosenberg & Parker. Matt noted that the collective vision each partner shares for the future of the company is a powerful motivator as they navigate forthcoming opportunities.

Profiles of the New Partners

Jack Rosenberg began his career at Susquehanna International Group and became a Producer at Rosenberg & Parker in 2018. During his tenure, he oversaw the expansion of the sales team, contributing to a more than threefold increase in revenue, earning him the title of President in 2025.

Harry G. Rosenberg joined the firm in 2021 after five successful years at The Blackstone Group, where he was instrumental in managing capital markets for private equity in the energy sector. He has rapidly climbed the ranks, becoming the Vice President, Financial Sponsors Practice Leader, and has significantly contributed to writing some of the firm’s largest bonds in its history.

James DiSciullo, coming from Exelon, became a part of Rosenberg & Parker in 2019. He took on the leadership role for the Energy Practice in 2022, where he oversaw tremendous growth in renewable and traditional energy sectors. In 2025, he became the Director of Advisory Production, focusing on continued success and growth across the advisory division.

Firm's Commitment to Clients

Chad Rosenberg, Sr. Partner, is excited to collaborate with the new partners, emphasizing their unique backgrounds and experiences which contribute to the dynamic leadership team at Rosenberg & Parker. He said, "All of our partners bring unique perspectives, and it has been incredible to work with them and leverage their expertise."

Jack added to this by reflecting on the impressive growth the firm has achieved, stating, "We have grown from around twenty employees to seventy-five today in just seven years. This trajectory has been exciting, but it's essential to remain mindful of our identity while expanding. We have a strong core team dedicated to upholding our firm's reputation and ensuring we provide outstanding service to our clients."

A Legacy of Expertise

Founded in 1944, Rosenberg & Parker's focus has consistently been on surety. This dedication to specialty knowledge in the broker space sets them apart in an industry often bogged down by less specialized practices. The firm prides itself on its four founding pillars: Expertise, Innovation, Integrity, and Service, guiding its operations throughout its more than 80 years in business.

In addition to the elevation of new partners, the firm continues to explore avenues of expansion and enhancement in service delivery, ensuring it meets the growing demands of the market and its diverse clientele. With three new leaders at the helm, Rosenberg & Parker is poised to continue its trajectory as a premier independent surety-only brokerage, ready to take on the challenges and opportunities that lie ahead.
