Tarlton, one of St. Louis’ largest general contracting and construction management firms, promted Sondra Rotty to president as elected by the company’s board of directors. In this new role, she also will retain her current position as chief operating officer.
The leadership transition is the result of several years of preparation and reflects the company’s commitment to continuity, stewardship and disciplined growth.
“Sondra is a proven leader who shares our deep commitment to client service, quality and the City of St. Louis,” said Tracy Hart, who will assume the role of executive chairman and chief executive officer.
Hart, along with her brother and business partner Dirk Elsperman, executive vice president and chief administrative officer, have served as Tarlton’s leaders since 1999.
Rotty joined Tarlton in 2005 as a project engineer and was named chief operating officer in 2024.
An accomplished builder, Rotty has played an integral role on many of Tarlton’s most visible projects, including the historic renovation of the Old Courthouse for the National Park Service and Gateway Arch Park Foundation, which garnered a 2025 AGCMO Construction Keystone Award; the Olin Business School expansion for Washington University in St. Louis; the East Building addition to the Saint Louis Art Museum; and the historic renovation of 900 Tucker Blvd., the former St. Louis Post-Dispatch building.
Rotty further advances Tarlton’s deep roots in St. Louis and the industry by serving on multiple corporate boards, including treasurer of the board for the Missouri Gateway Green Building Council and as chair of the Building Division of the Associated General Contractors of Missouri.
Rotty holds a Bachelor of Science degree in architectural engineering and a master’s degree in engineering management from Missouri University of Science and Technology.
