Callahan lands in top 10 of prestigious list of best workplaces in Massachusetts

BRIDGEWATER, MA – December 8, 2025 –  Callahan Construction Managers (Callahan), a full-service construction management company headquartered in Bridgewater, Mass. with offices in White Plains, NY, announced today that it has been named to the Boston Globe’s annual list of the “Top Places to Work” in Massachusetts, following its selection as one of the Boston Business Journal’s “Best Places to Work” earlier this year.

More than 120,000 Massachusetts employees at 314 organizations were surveyed for the annual Globe Top Places to Work list. The workers rated their employers on leadership, values, training, benefits, and other metrics, and the rankings are broken down into four size categories, based on the number of employees invited to take the survey nationwide. Callahan was ranked in the top ten of the medium category.

The company has been named to both the Boston Globe and Boston Business Journal lists for several years running. With consecutive years of financial and employee headcount growth, Callahan has made significant investments in its workplace culture, employee benefits, charitable giving, and other initiatives that reflect its commitment to being a top workplace in the state.

In addition to its constant reinvestment in its people and workplace, Callahan has also expanded geographically to create advancement opportunities for its employees. With an office in White Plains and projects recently underway in northern New England, including Portsmouth, NH, and Portland, ME, the company continues to grow. With several recent new hires and staff promotions, the company’s leadership team is committed to attracting and retaining the talent necessary to be a desirable place to work for years to come.

“When you become a top place to work, it’s not just signifying a strong benefits package or a comfortable work environment, but a commitment to reinvesting in our people and performance,” said Steven Callahan Jr., Vice President – Business Development for Callahan Construction. “We are proud of the foundation we’ve built to create opportunities for our company and the employees that power it, and we look forward to bringing that reputation to new clients and markets in the years to come.”

Multi-tenant project yields much-needed research space in Lexington

Callahan Construction Managers (Callahan),a full-service construction management company headquartered in Bridgewater, Mass., announced today that it has completed a multi-phase renovation project for Revolution Labs in Lexington. The project features a 180,000 square foot core and shell research building that is occupied by anchor tenants Orum Therapeutics and Alchemab Therapeutics.

The facility was designed from the ground up to support both cutting-edge research and the lifestyle needs of today’s life sciences pioneers. Orum Therapeutics is a private, clinical-stage biotechnology company that is pioneering the development degrader-antibody conjugates (DCAs) for cancer treatment, while Alchemab Therapeutics is developing solutions that utilize the immune system to create novel antibody therapies for challenging diseases.

With a proven track record for overseeing complex, technical, and multi-phase projects, Callahan’s familiarity with working in occupied spaces as well as the unique challenges of the life sciences environment proved impactful while working for Revolution Labs. The team was chosen to first oversee the core and shell of the facility, and then later retained to manage the fit-out of the interior office and lab spaces. The occupied nature of the building during the second phase posed challenges that included lining the pipes of the structure’s sanitary system while the building was in use, requiring restricted water use and proactive planning with laboratory tenants.

In addition, the ongoing supply chain concerns made procurement of advanced laboratory components challenging, including specialty HVAC and electrical equipment. Callahan utilized the pre-construction phase to build a schedule that met critical deadlines while also taking into account what equipment needed to be ordered first to ensure occupancy goals were not impacted by unpredictable delivery dates. Fortunately, strong relationships with suppliers and subcontractors ensured Revolution Labs maintained its preferred timeline.

With the health and safety of occupants a priority, Revolution Labs is on track to achieve WELL Certification. For Callahan, knowing it has helped build a facility that promotes both cutting-edge research and the health of its occupants makes the successful completion a source of pride for all involved.

“We are thrilled to see this new research facility come to life to support the groundbreaking efforts of the researchers that work here,” said Steve Callahan, Jr., vice president – business development, Callahan. “This project showcases the benefit of robust pre-construction planning, along with having a team that understands the specialized nature of lab construction. We wish Revolution Labs well as they utilize this space to its maximum potential.”
