- MYCPE ONE Insights Team

RSM US LLP, a leading provider of audit, tax, and consulting services for the middle market, has announced key changes to its executive leadership team (ELT) as part of a strategic succession planning initiative aimed at supporting the firm’s continued transformation into a digital-first, globally integrated organization.

The leadership restructuring includes the appointment of six new members to the ELT, each selected for their deep institutional knowledge and alignment with the firm’s long-term vision. The newly named leaders are expected to bring fresh perspectives to an already robust executive bench and support the firm’s evolution to meet the dynamic needs of clients and markets.

Key Executive Appointments

Sam Mascareno has been appointed Chief Operating Officer, succeeding Bill Gorman. Mascareno’s elevation marks a pivotal transition in operational leadership as the firm focuses on scalability and global growth.
Brandon Rucker will take over as Enterprise Assurance Leader, following Joel Shamon. Rucker’s role will be central in shaping the assurance strategy amid evolving regulatory and technological landscapes.
Stuart (Stu) Taub will assume the newly created position of Enterprise Markets and Industry Leader. This role is designed to strengthen RSM’s market presence and industry specialization.
Ericka Foster, currently serving as First Deputy General Counsel, will join the ELT, bringing legal expertise to the highest levels of strategic decision-making.
Rod Reimann, the firm’s Enterprise Sales Leader, will also join the ELT, enhancing the firm’s focus on client engagement and revenue growth initiatives.
Maria Severino, who leads both enterprise tax growth and Canadian tax operations, will bring her cross-border and industry-specific experience to the executive table.

Strategic Intent Behind the Appointments

According to Brian Becker, Managing Partner and CEO of RSM US LLP, these appointments are a deliberate step toward reinforcing the firm’s commitment to its core middle market focus while accelerating digital integration and global alignment.

“These leadership appointments position us to drive even greater impact for our clients, colleagues, and firm,” Becker stated. “Each leader brings a unique perspective and deep understanding of our business, culture, and the marketplace that reflects our longstanding commitment to the middle market as we continue to evolve to meet changing client needs and embrace our digitally connected future.”

With FY24 net revenue reaching $4 billion, the firm’s refreshed executive structure underscores its strategic priorities: operational excellence, client-centric innovation, and global collaboration. This leadership realignment also signals the firm's readiness to navigate complexity and drive sustainable growth across industries and borders.
