Constructing a Future

Bancroft celebrates 50 years of innovation and leadership

CONTRIBUTED BY BANCROFT CONSTRUCTION

FIFTY YEARS AGO, Bancroft Construction began as a vision fueled by the entrepreneurial spirit of Stephen M. Mockbee, a U.S. Marine Corps veteran with a passion for building. Mockbee’s journey started humbly as Mockbee Builders in 1975. With the transition to Bancroft Builders and eventually Bancroft Construction, his vision evolved into what is now a $250 million construction management firm.

Bancroft’s first project—a space renovation for sculptor Charles Parks at the historic Bancroft Mills in Wilmington, Del.—was more than just a construction project. It symbolized an opportunity for Mockbee to stake his claim on the construction industry and make an impact on the surrounding community.

During Bancroft’s 40th anniversary, Mockbee recalled, “Growth through customer satisfaction was more important than profit margins. Building a strong and loyal customer base is the key to sustaining long-term success.” That philosophy guided the company from its humble roots to becoming a trusted partner for prestigious projects, including the recently completed $250 million Longwood Gardens Reimagined project.

LEGACY AND BECOMING AN IDUSTRY LEADER

Over the decades, Bancroft transitioned from a small, family-driven business into an employee-owned company—a shift that reflected its deep commitment to collaboration and shared success. Founded on 12 guiding principles such as integrity, concern for others, continuous improvement, and trustworthiness, the company’s culture has remained steadfast while adapting to the evolving construction landscape.

In 2011, Greg Sawka assumed the role of president and CEO, guiding Bancroft into its next era of growth. Under his leadership, Bancroft expanded its reach throughout the Mid-Atlantic region with offices in Princeton, N.J., and Salisbury, Md., and embraced technology-driven innovations in project management.

MAJOR ACHIEVEMENTS: A CELEBRATION OF IMPACT

From constructing the largest living green wall in North America at Longwood Gardens to delivering Delaware’s first LEED-certified school, Bancroft’s achievements reflect its dedication to sustainability and excellence. Key milestones include:

• DuPont OPD1: The largest project in Bancroft’s early history

• P.S. DuPont Middle School: The largest school renovation in Delaware’s history

• Longwood Gardens East Conservatory Plaza: Home to the nation’s largest living green wall

• Hanby Elementary School: Delaware’s first LEED-certified school

As Bancroft looks to the future, its focus remains on bettering communities, fostering innovation, and building lasting relationships. “Our guiding principles are more than words—they are the foundation of how we approach every project and partnership,” says Sawka.

LOOKING AHEAD: BUILDING THE NEXT 50 YEARS

Bancroft’s commitment to its team, clients, and trade partners continues to shape its legacy. Guided by a culture of integrity and innovation, the company’s trajectory is clear: to lead with purpose and leave an enduring impact on the communities it serves.

From its modest beginnings in a Marine Corps veteran’s vision to becoming an industry leader, Bancroft’s journey is a testament to perseverance, teamwork, and a relentless pursuit of excellence. Here’s to 50 years of not just constructing buildings but bettering our communities, driving innovation, and building lasting relationships.
