Meet the executive search leaders redefining who leads America’s most powerful companies.
For decades, they worked in the background. While shareholders debated earnings and boards wrestled with strategy, a small, elite cadre of executive search consultants were doing something quietly consequential: helping decide who would actually lead. Their influence was significant, even if their names rarely appeared in the headlines.
That profile is changing. As the cost of poor leadership decisions has grown more visible and more consequential, the professionals guiding those decisions have become more central to how organizations think about the future. A single misaligned CEO hire can set a company back by years. Boards are held to higher standards on composition and succession planning than ever before. And the definition of effective leadership has shifted considerably in a short period, shaped by remote work, shareholder activism, ESG expectations, and rapid technological change.
The best executive search professionals today are no longer simply matching candidates to roles. They advise boards on structure and composition, counsel chief executives through transitions, and help organizations think more clearly about the kind of leadership they actually need. It is substantive, ongoing advisory work, and it matters.
Within the leading executive search firms, it is individual practitioners who build the reputations and relationships that clients rely on over time. These are the advisors boards turn to first, not just when a seat is open, but when they are thinking through governance, succession, and long-term leadership strategy. The following 13 professionals are among the most respected in the field today.
Jim Citrin, Consultant, CEO & Board Practice Spencer Stuart
Few names in executive search carry more weight than Jim Citrin’s. With more than 25 years at legacy search firm Spencer Stuart, he has led more than 750 CEO and senior executive searches, a volume that few in the industry can match. Yet it is not the quantity but the depth of his work that sets Citrin apart. He leads the firm’s North American CEO Practice and co-leads its Board Practice, operating at the intersection of succession strategy and governance in ways that have made him one of the most trusted advisors to corporate America’s most powerful boards.
Before joining Spencer Stuart, Citrin held roles at McKinsey, Goldman Sachs, and Morgan Stanley, a financial background that informs his analytical approach to leadership assessment. He also served two decades on Spencer Stuart’s own Board of Directors, giving him a firsthand understanding of board dynamics that he brings to every client engagement. His Vassar and Harvard Business School education grounded an intellectual curiosity that found expression in eight books on leadership and career development, including Leading at a Distance and You Need a Leader, Now What? Works that have shaped how a generation of executives thinks about organizational leadership.
Citrin has been repeatedly honored in the National Association of Corporate Directors’ Directorship 100, and his commentary on executive succession and career management appears regularly in The Wall Street Journal, Harvard Business Review, and The New York Times. He is a trustee of Vassar College and Wesleyan University, and serves on the board of the International Tennis Hall of Fame.
Rebecca C. Thornton, Consultant, Board Advisory Practice, North America Spencer Stuart
With more than 25 years advising boards, CEOs, and aspiring directors, Rebecca Thornton has built one of the most respected board governance practices in the country.
As co-leader of the North American Board Advisory Practice at Spencer Stuart, she brings a combination of institutional knowledge and cross-sector experience, having counseled clients through CEO transitions, governance reform, and shareholder engagement challenges across industries ranging from financial services to technology.
Thornton’s seven-year tenure leading JPMorgan’s Director Advisory Services division, which served more than 1,500 corporate clients, gave her an unusually thorough view of the demand side of board recruiting. That experience carried back to Spencer Stuart has made her one of the more informed voices on board composition. She has championed diversity on corporate boards and helped elevate governance practices for companies navigating complex transitions.
A graduate of Colby College and an NACD Directorship 100 honoree, Thornton’s insights have appeared in The New York Times and Bloomberg. She co-chairs the governance committee at New Canaan Country School and has contributed to leadership podcasts including Making Sense, where she speaks to broader audiences on the evolving nature of board responsibilities.
Jason Baumgarten, Consultant, Global Board and CEO Practice Spencer Stuart
Jason Baumgarten brings the precision of a McKinsey consultant and the product instincts of a former Microsoft program manager to his work at Spencer Stuart. As Head of the firm’s Global Board and CEO Practice, he has personally guided more than 250 CEO and board transitions, a track record that has established him as one of the more analytically rigorous succession strategists in the business.
Operating out of Seattle, Baumgarten has natural fluency with enterprise technology and consumer internet clients, though his practice spans from Fortune 200 conglomerates to high-growth private equity-backed firms. He is known for designing governance frameworks that don’t simply fill a vacancy but align CEO profile with long-term strategic intent, a distinction that clients in complex transformation situations have found particularly valuable.
Baumgarten holds an MBA from Stanford and a BA in Economics from Vassar. He chairs the board of IslandWood, an environmental education nonprofit, and has become a recognized voice on sustainability and socially responsible leadership at the executive level. His commentary on board governance and CEO leadership trends appears regularly in Harvard Business Review, The Wall Street Journal, and Forbes.
Jane Edison Stevenson, Vice Chair, Board & CEO Services Korn Ferry
Jane Edison Stevenson is among the most influential figures in global CEO succession. As Vice Chair of Board and CEO Services at Korn Ferry, she coordinates a worldwide network of more than 100 partners focused on CEO succession and board effectiveness, a capability she built over many years at the firm. BusinessWeek named her among its “100 Most Influential Search Consultants in the World.”
What distinguishes Stevenson is her long-standing commitment to broadening who gets to lead. Her collaboration with the Rockefeller Foundation’s “100×25” initiative, which sought to place 100 women in Fortune 500 CEO roles by 2025, reflects a career-long view that diversity in leadership is a performance advantage. She is the co-author of Breaking Away: How Great Leaders Create Innovation that Drives Sustainable Growth, a recipient of the Maurice Holland Award, and a sought-after keynote speaker at forums including the Detroit Economic Club.
Stevenson also sponsors the Power of ALL initiative, which works to strengthen diverse representation in leadership pipelines, and has been repeatedly recognized in the NACD Directorship 100 for her influence on boardroom practice.
Tierney Remick, Vice Chairman & Co-Leader, Board and CEO Services Korn Ferry
Tierney Remick has spent more than two decades in executive search building trusted relationships with boards and chief executives across industries. As Vice Chairman and Co-Leader of the global Board and CEO Services practice at Korn Ferry, she advises organizations on succession planning, governance best practices, and aligning leadership capability with long-term organizational purpose.
Her career has included global leadership of the consumer markets practice and membership on the firm’s global operating committee, roles that have given her broad exposure to organizational life from strategy through leadership transition. A Princeton graduate, Remick is a director of Make-A-Wish America and serves on the Women’s Leadership Board at Harvard Kennedy School’s Women and Public Policy Program.
She is a frequent contributor to CNBC, The Wall Street Journal, and Fortune, where her insights on inclusive board practices and sustainable enterprise leadership have earned her a steady national following.
Bonnie W. Gwin, Vice Chair & Co-Managing Partner, Global CEO & Board Practice Heidrick & Struggles
Bonnie Gwin has spent more than two decades at Heidrick & Struggles and is among the most recognized executives in the search industry. As Vice Chair and Co-Managing Partner of the Global CEO and Board of Directors Practice, she has advised some of the world’s largest companies on CEO succession, board effectiveness, and leadership diversity, drawing on both the commercial experience of her 13 years at IBM and the governance depth accumulated over a long career in executive search.
Gwin has been honored with the Association of Executive Search and Leadership Consultants Award of Excellence and has been repeatedly named to the NACD Directorship 100. The firm also recognized her with its John E. Struggles Award for embodying integrity and partnership. A Georgetown graduate, she serves on the boards of the Cleveland Clinic and Georgetown University, and previously chaired Make-A-Wish America.
Her philanthropic commitments reflect the same values she brings to her professional work: a belief that effective leadership, in business and civil society alike, is built on integrity, inclusion, and a genuine sense of responsibility.
Margot McShane, Co-Lead, Global Board and CEO Advisory Practice Russell Reynolds Associates
Margot McShane’s work sits at the intersection of leadership assessment, governance strategy, and succession planning. At Russell Reynolds Associates, she co-leads the Global Board and CEO Advisory Practice, working with Fortune 500 companies, private equity firms, and nonprofits to evaluate C-suite capabilities, prepare high-potential executives for the CEO role, and align board structures with long-term strategic goals.
Known for an analytical and pragmatic approach, McShane combines a clear-eyed view of what effective leadership looks like with a commitment to transparent governance. Her work has shaped how a number of major organizations think about leadership readiness, and her advocacy for diversity of thought in executive decision-making has informed the firm’s approach to succession planning.
A frequent contributor to industry panels and leadership forums, McShane is a recognized voice in the ongoing discussion about how boards and executives need to adapt to rising stakeholder expectations. Her advisory work and public engagement have made her a respected figure in corporate governance circles.
Jack “Rusty” O’Kelley III, Co-Leader, Global Board & CEO Advisory Practice Russell Reynolds Associates
Rusty O’Kelley brings an unusually broad foundation to his work in governance advisory: the legal training of a Yale-educated corporate attorney, the strategic consulting background of a Katzenbach Partners veteran, and the governance experience of a career advising complex organizations.
As Co-Leader of the Global Board and CEO Advisory Practice at Russell Reynolds Associates, he works with public companies, large family businesses, and major institutions on CEO succession, board performance, and resilience against shareholder activism.
His annual publication Global Trends in Corporate Governance, produced continuously since 2016, has become a useful reference for directors and institutional investors tracking shifts in boardroom practice. His research on shareholder activism reflects a proactive approach to governance that has been well received by boards facing more assertive institutional shareholders.
O’Kelley graduated summa cum laude in accounting from Hampton University before earning his J.D. at Yale Law School. He serves on the board of Lincoln Center Theater and advises the Yale Law School Center for the Study of Corporate Law.
Ash Wendt, President & Founding Partner Cowen Partners Executive Search
Ash Wendt represents a different but increasingly relevant model in executive search: the focused, founder-led search firm built on specialization, speed, and close client relationships. As President and Founding Partner of Cowen Partners Executive Search, Wendt has developed one of the country’s most recognized search firms, known for efficient, data-driven placements across all C-suite functions.
Before co-founding Cowen Partners, Wendt demonstrated strong business development instincts at Clearwire, where he led one of the top-performing national channels. That experience shaped his view that effective executive search requires genuine commercial understanding alongside talent assessment, not just an eye for credentials but an understanding of how leaders actually drive business results.
Wendt contributes thought leadership through the Entrepreneur Leadership Network, writing on evolving leadership models including the co-CEO framework and its practical implications for organizational structure. His firm works across technology, healthcare, financial services, and consumer sectors, and he approaches executive search as a strategic function rather than a transactional one.
Charles “Chuck” Gray, Co-Head, North American Board & CEO Practice Egon Zehnder
Chuck Gray came to executive search with the credentials of a financier, having held roles at Bain, Credit Suisse First Boston, Liberty Mutual, and J.P. Morgan. As Co-Head of the North American Board and CEO Practice at Egon Zehnder, he advises public company boards and private equity firms on CEO succession and performance evaluation across financial services, technology, consumer, industrial, and healthcare sectors.
Gray is known for integrating governance insight with leadership analytics, a combination that reflects his dual background in strategic finance and executive assessment. His work helps boards not only identify capable leaders but build the frameworks needed to sustain leadership quality over time. He also co-led the North America Diversity Practice, a role that reflects a personal commitment to broadening representation in boardrooms.
A Morehouse College undergraduate and Wharton MBA, Gray brings both analytical rigor and a people-centered perspective to his advisory work. His approach to succession planning, treating leadership pipelines as strategic assets rather than contingency measures, has informed how a number of boards approach that responsibility.
Pamela Warren, Co-Lead, North America CEO & Board Practice Egon Zehnder
Pamela Warren is a key contributor to Egon Zehnder’s board and CEO advisory work across North America. As Co-Lead of the CEO and Board Practice, she advises directors and chief executives on leadership transitions, succession readiness, board composition, and governance best practices, combining analytical discipline with a genuine focus on the human side of leadership evaluation.
Warren’s work is shaped by a forward-looking view of the demands now placed on boards: increased scrutiny around ESG oversight, accelerating digital transformation, and growing expectations from a wider range of stakeholders. Her ability to help organizations align strategic priorities with leadership capability has made her a valued partner to boards working through complexity.
Through her advisory work, Warren contributes meaningfully to how modern boardroom practice is evolving and to the development of leadership talent across the continent.
Lisa Blais, Co-Lead, US Board & CEO Practice Egon Zehnder
Lisa Blais brings something relatively rare to executive search: more than two decades of direct operational experience before entering the advisory side of the industry.
Before joining Egon Zehnder in 2008, she served as President of ITT’s Flow Control Division and held senior leadership roles across global manufacturing and technology-focused sectors. That background gives her a grounded, practical perspective on what effective industrial and operational leadership actually requires.
At Egon Zehnder, Blais rose to co-lead the US Board and CEO Practice, manage the Boston office, and serve on the firm’s global Board of Directors. She co-founded the firm’s US Diversity Council and Corporate Governance Exchange, initiatives that have supported more inclusive practices in executive search.
An MIT engineer and Harvard Business School graduate, Blais is an active mentor to women executives and a member of the NACD New England Chapter. Her work reflects a commitment to helping organizations build stronger leadership foundations, not just fill immediate vacancies.
Shawn Oglesbee, Managing Partner & Leader, Board Services Practice ON Partners
Shawn Oglesbee built a strong record at CTPartners, becoming the youngest Managing Partner in the firm’s three-decade history, before co-founding ON Partners in 2006. The goal was to offer a more focused, relationship-driven alternative to larger multinational search firms. Nearly two decades on, ON Partners is recognized as one of the leading retained executive search firms in the United States and has appeared on the Inc. 5000 list for sustained growth.
At ON Partners, Oglesbee leads the Board Services practice, advising public companies, private equity-backed firms, and venture-funded organizations on board and CEO recruitment. With more than 40 director appointments to his credit and a practice centered on governance alignment and succession planning, he has become a respected figure in board advisory work, particularly for companies that may be underserved by the largest global firms.
His approach centers on long-term relationships, transparency, and genuine partnership with boards and chief executives. His collaboration with former search industry veteran Stephen Mader to expand the firm’s board advisory capabilities reflects a consistent commitment to improving the quality of counsel provided to clients.
The Strategic Talent Advisor
What connects these 13 individuals, across different firms, geographies, and areas of focus, is a shared understanding that executive search has changed in meaningful ways. The work is no longer primarily about filling vacancies. It has become an ongoing advisory relationship between search professional and board, one built on trust, grounded in governance knowledge, and oriented toward long-term organizational health.
Boards that engage with advisors of this caliber as true partners, not just when a seat opens but as part of how they think about leadership and succession more broadly, tend to be better prepared for the transitions that inevitably come.
The professionals featured here have built careers on exactly that premise. Their work shapes some of the most significant leadership decisions in American business, and their influence on how organizations think about talent and governance continues to grow.
