Mark David Lerner (born September 1953) is an American businessman who serves as the managing principal owner of Major League Baseball's Washington Nationals and the managing owner of Lerner Enterprises, one of the largest privately held real estate companies in the Washington, D.C., metropolitan area. The eldest son of real estate magnate Ted Lerner, who founded the family business and led the ownership group that purchased the Nationals in 2006, Mark Lerner assumed the role of managing principal owner of the franchise in 2018 when his father, then 92 years old, stepped back from day-to-day control. Under his ownership, the Nationals won the 2019 World Series, the first championship in the franchise's Washington-era history. Beyond baseball, Lerner has been involved in the management and expansion of Lerner Enterprises' extensive portfolio of commercial and residential properties across the mid-Atlantic region. A graduate of George Washington University, he has maintained ties to his alma mater and the broader Washington, D.C., community through business and philanthropic activity. His tenure as principal owner of the Nationals has drawn both praise, particularly surrounding the 2019 championship, and scrutiny regarding organizational direction in subsequent years.

Early Life

Mark David Lerner was born in September 1953 in the Washington, D.C., area. He is the eldest son of Ted Lerner and Annette Lerner. Ted Lerner, a child of immigrants who grew up in Washington, built Lerner Enterprises into one of the largest privately held real estate organizations in the United States, with holdings spanning commercial office buildings, shopping centers, hotels, and residential communities throughout the Washington metropolitan area and beyond.

Mark grew up immersed in the family real estate business. The Lerner family was a prominent fixture in Washington-area business and civic life, and the family's real estate empire provided the foundation upon which Mark Lerner would later build his career. He has siblings who have also been involved in Lerner Enterprises and the Nationals ownership group, making the franchise a family-operated enterprise.

Education

Mark Lerner attended George Washington University in Washington, D.C., where he earned a Bachelor of Business Administration (B.B.A.) degree. His connection to the university has remained strong throughout his career. In 2025, George Washington University announced that Lerner, along with fellow alumnus Mark Shenkman and D.C. Delegate Eleanor Holmes Norton, would receive honorary degrees at the university's Commencement ceremony on the National Mall, recognizing his contributions to business and the Washington community.

Career

Lerner Enterprises

Mark Lerner has served as the managing owner of Lerner Enterprises, the family-founded real estate firm that his father, Ted Lerner, established and built into a major force in the mid-Atlantic real estate market. The company's portfolio encompasses commercial office properties, retail shopping centers, hotels, and residential developments, concentrated primarily in the Washington, D.C., metropolitan area but extending to other markets as well.

Under the broader Lerner Enterprises umbrella, the family has managed a diverse array of holdings. In November 2025, for example, Lerner Enterprises sold the ground lease to a multifamily property in suburban Miami-Dade County, Florida, at a significant discount, reflecting the company's active management of its national real estate portfolio.

Mark Lerner's role at the company placed him in a leadership position overseeing one of the region's most significant private real estate enterprises, and it was the family's substantial financial resources derived from real estate that underpinned the eventual acquisition of the Washington Nationals.

Acquisition of the Washington Nationals

In 2006, Major League Baseball approved the sale of the Washington Nationals franchise to an ownership group led by Ted Lerner. The Lerner family's bid was selected from a competitive field of prospective buyers to purchase the team, which had relocated from Montreal (where it had been the Expos) to Washington, D.C., in 2005 and had been operated by MLB itself during the transition period.

The ownership group was a family affair. Ted Lerner served as the managing principal owner, with Mark Lerner and other family members taking active roles in the franchise's operations and governance. From the outset, the Lerners' ownership was distinguished by its family-controlled structure, with multiple members of the Lerner family occupying positions of authority within the organization. Mark Lerner took a prominent role in the business operations of the club and served as a key figure in the ownership hierarchy beneath his father.

Managing Principal Owner

On June 14, 2018, the Washington Nationals announced that Mark Lerner had been named the managing principal owner of the franchise, succeeding his father Ted Lerner, who was then 92 years old. The transition had been anticipated for some time, as the elder Lerner had been gradually reducing his involvement in daily operations. Mark Lerner's elevation to the top ownership role formalized his position as the day-to-day decision-maker for the franchise.

The timing of the transition placed Lerner at the helm of the organization during a period of both triumph and significant upheaval. The Nationals had been built into a perennial contender during the 2010s under general manager Mike Rizzo and a succession of managers, with a roster that at various points featured players such as Bryce Harper, Max Scherzer, Stephen Strasburg, and Ryan Zimmerman.

2019 World Series Championship

The crowning achievement of Lerner's tenure as managing principal owner came in 2019, when the Washington Nationals won the World Series, defeating the Houston Astros in seven games. It was the first World Series title in the franchise's history as the Washington Nationals and the first for a Washington-based baseball team since the original Washington Senators won in 1924. The championship represented the culmination of years of investment in player development and free-agent acquisitions under the Lerner ownership group.

The 2019 Nationals were managed by Dave Martinez and led on the field by players including Juan Soto, Anthony Rendon, Stephen Strasburg, and Max Scherzer. The team overcame a 19–31 start to the season to reach the postseason as a Wild Card entry, then proceeded to win the Wild Card Game, the National League Division Series, the National League Championship Series, and the World Series in a historic run.

Post-Championship Period and Organizational Scrutiny

Following the 2019 World Series victory, the Nationals entered a period of decline. Key players departed through free agency, including Anthony Rendon, who signed with the Los Angeles Angels after the 2019 season. The team traded Max Scherzer and other veterans during the 2021 season, signaling a rebuild, and subsequently traded Juan Soto in 2022. The Nationals posted losing records in consecutive seasons, and questions arose about the organization's direction under Lerner's leadership.

In September 2025, a report in The Washington Post examined the state of the franchise under the Lerner family's ownership, describing the organization as appearing "directionless" at a critical juncture in its history. The report suggested that multiple members of the ownership group had influence over baseball decisions, leading to what some within the sport characterized as an inefficient structure with "too many hands on the wheel." MLB Trade Rumors reported on the same findings, noting that the Nationals' ownership had been criticized as "inefficient" and "directionless."

In July 2025, the Nationals dismissed general manager Mike Rizzo and manager Dave Martinez, both of whom had been with the organization for many years and had been central figures in the 2019 championship run. The firings were characterized by some commentators as long-overdue moves during a stalled rebuilding effort.

Subsequently, the Nationals hired Paul Toboni as their new head of baseball operations. In October 2025, The Washington Post reported on the Lerner family's commitment to the new leadership, noting that the success of the rebuilding effort would depend on whether ownership was willing to provide Toboni with the resources and autonomy needed to reshape the organization.

Personal Life

Mark Lerner is married to Judy Lenkin Lerner. The couple has been involved in philanthropic activities in the Washington, D.C., area.

Lerner is the son of Ted Lerner and Annette Lerner, and has been part of a close-knit family that has worked together across both the real estate and baseball enterprises. The Lerner family's involvement in the Washington Nationals has been characterized by the participation of multiple family members in ownership and operational roles.

Health

In August 2017, it was reported that Mark Lerner was recovering from cancer treatment. The Washington Business Journal reported on Lerner's recovery during this period. As part of his cancer treatment, Lerner had a leg amputated. MLB.com reported that Lerner was free of cancer following the amputation, and he continued in his role with the Nationals and Lerner Enterprises. Lerner's return to his ownership duties after the surgery and cancer treatment was noted as a testament to his determination to remain active in the franchise's operations.

Recognition

As managing principal owner, Mark Lerner received the Commissioner's Trophy when the Washington Nationals won the 2019 World Series, the franchise's first championship. The victory was one of the most celebrated moments in Washington, D.C., sports history, and it cemented the Lerner family's legacy as the ownership group that brought a World Series title to the nation's capital for the first time in nearly a century.

In March 2025, George Washington University announced that Lerner would be among the recipients of honorary degrees at the university's Commencement ceremony, to be held on the National Mall. The university recognized Lerner alongside fellow alumnus Mark Shenkman and D.C. Delegate Eleanor Holmes Norton, honoring their contributions to their respective fields and to the broader Washington community.

Lerner's career has also been recognized in the context of his family's broader impact on the Washington, D.C., region. The Lerner family has been one of the most prominent business families in the metropolitan area for decades, with their real estate holdings shaping the development of commercial and residential communities across Maryland, Virginia, and the District of Columbia.

Legacy

Mark Lerner's legacy is closely intertwined with that of the Lerner family's dual role in Washington-area real estate and Major League Baseball. As the managing principal owner who presided over the Nationals' 2019 World Series championship, he occupies a significant place in the history of professional sports in Washington, D.C. The 2019 title ended a drought that had lasted since 1924, when the original Washington Senators won the World Series, and it brought a level of sports euphoria to the city that had not been seen in decades.

At the same time, the post-championship years have presented challenges. The departure of star players, the onset of a rebuilding period, and questions about organizational structure have placed scrutiny on Lerner's stewardship of the franchise. The hiring of Paul Toboni as head of baseball operations in 2025 represented a potential turning point, and the franchise's trajectory under new baseball leadership will likely define the next chapter of the Lerner ownership era.

Through Lerner Enterprises, the family continues to maintain a significant presence in the commercial real estate market, with properties spanning multiple states and asset classes. Mark Lerner's dual role as a real estate executive and baseball owner places him among the relatively small number of American business figures who have operated at the highest levels of both industries simultaneously.
