Radelmis Rosario – Cambrex

Radelmis Rosario has built a career making the invisible essential — turning Cambrex‘s Durham facility into a catalyst for the science that changes lives. When a 50°C walk-in stability chamber had to be designed, built, and operational in under a month, most facilities professionals would have penciled in a realistic six-month timeline and pushed back. Rosario got to work.

The chamber—a custom-built chamber required to meet an urgent client need—was delivered on time. No drama, no delay, just execution. It is the kind of story that rarely makes it into industry headlines, but for Rosario, associate director of facilities at Cambrex, it captures everything that defines the role: relentless problem-solving, cross-functional coordination, and an unwavering focus on keeping science moving forward. In a field where operational excellence is often invisible until something breaks, Rosario has built his career by making sure it never does.

A foundation built on systems thinking

Rosario joined Cambrex as a facilities manager, building his reputation one reliable system at a time. Over the years, his focus expanded from maintaining building infrastructure to influencing site strategy, mentoring team members, and driving capital projects that aligned operations with business growth. That evolution eventually led to his promotion to associate director—a title that reflects both broadened responsibility and a deeper integration with organizational priorities.

“Being promoted to associate director has allowed me to take a broader view of the organization, balancing daily operational needs with long-term planning,” Rosario says. “It has given me the opportunity to influence site strategy, mentor team members, and contribute to business growth while continuing to support the scientific work taking place within our facility.”

Cambrex is a leading contract development and manufacturing organization serving the pharmaceutical industry, with a global network of facilities focused on supporting small molecule active pharmaceutical ingredient development and manufacturing. At its Durham, North Carolina site—a 120,000-square-foot operation where Rosario is based—the company offers a broad spectrum of services, including analytical development, stability testing, and synthesis capabilities that serve customers across the drug development lifecycle.

At a facility of this scale, every system carries weight. HVAC failures, equipment malfunctions, and utility disruptions are not abstract risks—they are events that can cascade directly into delayed programs and downstream patient impact.

“Every system plays a role in supporting the scientists and analysts who perform critical work every day,” Rosario explains. “The work conducted within our facility ultimately contributes to therapies and products that impact patients’ lives. We cannot afford to wait for failures; we must anticipate them before they occur.”

Expanding capacity without expanding walls

One of the more visible current efforts is an expansion of Cambrex’s stability storage capabilities at the Durham site. To meet growing customer demand for 25°C/60% relative humidity storage conditions, Rosario’s team is installing two new walk-in chambers—one measuring 8 by 40 feet and another at 8 by 16 feet—adding to an existing fleet of seven chambers already on-site.

What makes the project worth noting is not simply the addition of equipment, but the philosophy behind it. Rather than pursuing costly new construction, the team has found creative ways to maximize value within the existing footprint—repurposing underutilized spaces and designing lean laboratory environments that allow capacity to scale without a corresponding spike in capital expenditure. The approach reflects a core principle that Rosario applies across every major project: spend strategically, think creatively, and never underestimate what an existing space can become.

That same resourcefulness shaped a recent conversion of existing space into an ICP-MS laboratory—a project that required Rosario’s team to transform an active area into a highly specialized analytical environment without disrupting ongoing operations. The effort required coordination among laboratory stakeholders, quality teams, environmental health and safety, contractors, and facility resources, while managing utility modifications and specialized exhaust requirements in a live research setting.

“Projects like this require a different way of thinking about facilities,” Rosario says. “Rather than viewing space as fixed, we look for opportunities to creatively repurpose existing areas to support new capabilities. As customer demand evolves, we must continuously evaluate how our facilities can adapt quickly and efficiently.”

The people behind the systems

Behind every successful project is a team, and Rosario oversees five direct reports alongside an extended network of outsourced vendors. Keeping standards consistent across that mix requires more than contracts and compliance checklists—it requires a shared sense of purpose.

His approach is straightforward: treat vendors as partners, not transactions. Clear performance expectations, regular reviews, and a deliberate effort to connect outsourced workers to the site’s broader mission have helped him build a unified culture across a workforce that does not all share the same employer. When everyone understands the purpose behind the work and feels connected to the site’s success, accountability becomes collective rather than contractual.

That same people-centered philosophy extends to Rosario’s work outside of Cambrex. As an adjunct instructor teaching programmable logic controllers and industrial automation, he has a firsthand view of how interest in the skilled trades grows when students encounter real-world applications. It sharpens his perspective on one of the industry’s more pressing challenges.

“We need to do a better job of showcasing the opportunities available within the skilled trades and facilities profession,” he says. “Many young people are unaware that these careers can offer strong compensation, career advancement, technical challenges, and meaningful work. Today’s facilities professionals are solving complex problems using sophisticated tools, and that message needs to be communicated more effectively to future generations.”

Showing your work

In facilities management, success often looks like nothing happening. Labs run, systems hold, programs proceed on schedule—and no one thinks about why. For someone like Rosario, whose team operates almost entirely out of the spotlight, making that value legible to organizational leadership has been as important a skill as any technical one.

As he has moved into senior leadership, he has increasingly connected facilities performance to the metrics that resonate at the business level: reliability rates, energy savings, risk reduction, project delivery timelines, and compliance support.

The site’s Annual Energy Management Progress Report offers a clear illustration of that shift. Covering utility optimization initiatives completed between March 2025 and February 2026, the report details work across chillers, pump controls, air handlers, and exhaust fans that reduced the site’s energy intensity from 4.3 kWh/sqft to 3.6 kWh/sqft—a 15.6 percent reduction in energy consumption. The improvements generated $68,550.05 in verified annual cost savings against an implementation investment of only about $10,000, an exceptional return that Rosario points to as evidence of what disciplined, low-capital facilities work can deliver. Beyond the balance sheet, the initiatives improved system performance and operational efficiency, reinforcing a continued commitment to sustainability and responsible resource management.

The conversation has shifted from maintenance costs to strategic enablement. Prioritization, he notes, always starts with understanding risk—safety and compliance rise to the top, followed by operational impact, and then broader business continuity. Strong systems, clear communication, and a capable team allow multiple priorities to move forward simultaneously rather than sequentially, which is the only way to keep pace with the demands of a dynamic life sciences environment.

“Facilities are increasingly viewed as a business partner that enables growth, supports customer commitments, and creates the infrastructure necessary for scientific success,” he reflects.

There is a quiet confidence in how Rosario talks about the work—the kind that comes not from visibility, but from knowing precisely what keeps things running. The custom chamber was built in a month. The laboratory converted without a day of lost productivity. The capacity expanded without breaking ground. These are the accomplishments that define his tenure and, in a broader sense, define what facilities leadership can be: not a cost center, but a catalyst for the science that matters most.
