Segal Marco’s Dual-Leadership Bet on Stability and Growth

NEW YORK, NY – June 09, 2026

In the world of investment consulting, where market volatility and short-term pressures often dominate the narrative, announcements of leadership changes are common. Yet, the recent move by Segal Marco Advisors to appoint Seth Almaliah and John Marco as Co-Presidents, effective July 1, 2026, is a development worth examining more closely. This is not a routine changing of the guard; it is a quiet but powerful signal about how enduring firms build resilience and prepare for the future. By embracing a dual-leadership model, the firm is making a strategic bet on a structure designed to navigate an increasingly intricate global landscape while doubling down on its core principles.

The transition, which follows the retirement of esteemed outgoing President Sue Crotty, is being presented as a natural step in the firm’s long-term succession planning. However, beneath this smooth narrative lies a deliberate architectural choice. In an industry grappling with consolidation, fee pressures, and technological disruption, Segal Marco is signaling that the path forward requires not just a single, visionary leader, but a partnership built on complementary strengths.

A Deliberate Design for Complexity

The press release speaks of addressing the “increased complexity of the investment consulting landscape.” This is not corporate jargon; it is a direct acknowledgment of the powerful forces reshaping the industry. Today's institutional clients demand more than just manager selection. They require sophisticated guidance on everything from navigating volatile geopolitical climates and shifting regulatory frameworks to integrating advanced risk analytics and meeting ambitious ESG mandates. The sheer breadth and depth of expertise required have stretched the traditional leadership model to its limits.

Segal Marco’s response is to divide and conquer, creating a structure that mirrors the multifaceted nature of the challenges it faces. The co-presidency model allows for a level of specialized focus that is difficult for a single executive to maintain. While one leader can concentrate on the internal engine of the firm—the research, the risk management, the service delivery—the other can focus on the external landscape—market strategy, client engagement, and intellectual capital. This dual-pronged approach is designed to enhance both operational excellence and strategic agility, ensuring that no critical area is neglected in the pursuit of the other. It is a recognition that in the 21st-century economy, resilience is often a team sport.

The Power of Complementary Leadership

The choice of Seth Almaliah and John Marco is a masterclass in strategic team building. Their careers, while both impressive, represent two different but equally vital pathways to leadership, and their new roles are tailored to leverage these distinct backgrounds.

Seth Almaliah embodies the principle of permanence. With 27 years at the firm, his career trajectory from analyst to Co-President is a powerful testament to the organization's commitment to cultivating internal talent. Having most recently served as Head of Client Service, he possesses an intimate understanding of the firm's operational core. As Co-President, he will take charge of the primary practice areas, including the critical functions of investment manager research, risk management, and performance measurement. He represents the steady hand on the tiller, ensuring the firm’s service delivery remains best-in-class. “Our success is rooted in our ability to prioritize our clients’ long-term goals over short-term gains,” Almaliah stated, underscoring his focus on the foundational elements of client trust.

John Marco, in contrast, represents strategic growth and adaptation. He joined the firm in 2017 through the acquisition of his Marco Consulting Group, a move that significantly expanded the firm’s capabilities and reach. With 21 years of experience and a recent role as Head of Client Growth and Engagement, his expertise lies in market dynamics and strategic positioning. His new mandate as Co-President will focus on market leadership, intellectual capital, marketing, and business development. He is tasked with looking outward, expanding the firm’s presence and ensuring its voice is a leading one in the industry. “As a privately held firm, our focus and decisions are made in the best interests of our clients and our people,” Marco commented, highlighting the firm's structural advantage in a market often driven by quarterly returns.

Together, they form a leadership dyad: Almaliah ensures the engine runs flawlessly, while Marco charts the course and scans the horizon. This is not a structure of redundancy, but one of reinforcement.

Succession as a Strategy for Permanence

This leadership evolution is deeply rooted in the DNA of the parent company, Segal. As a privately held and independent firm, it has long prioritized long-term stability over the kind of private equity-fueled churn that has reshaped many of its competitors. The recent appointment of 35-year company veteran John DeMairo as President and CEO of the parent company, to whom Almaliah and Marco will report, further cements this philosophy. The entire succession process, from DeMairo at the top to the co-presidents at Segal Marco, has been an internal affair, meticulously planned and executed to ensure continuity.

The close collaboration between the incoming co-presidents and the retiring Sue Crotty is another hallmark of this thoughtful approach. It ensures a seamless transfer of institutional knowledge and client relationships, mitigating the disruption that so often accompanies leadership changes. This strategy stands in stark contrast to the abrupt, often reactive, leadership shifts seen elsewhere. It reflects a belief that permanence is not about resisting change, but about managing it with foresight and intention.

By splitting the presidency, Segal Marco is not just filling a vacancy; it is redesigning the role for a new era. It is an acknowledgment that the modern investment landscape is too complex, the demands too varied, for a singular approach. This dual-leadership structure is a strategic investment in the firm's capacity to deliver consistent value, navigate headwinds with strength, and solidify its reputation as a winner in an unpredictable global landscape.
