Must Have Ingredients for a Perfect Partnership Include Trust, Expertise, Innovation, and Commitment
With this year’s 2025 BOMA International Conference & Expo taking place in Boston, we were especially determined to welcome the commercial real estate industry to our hometown and reflect the spirit of UG2 and our city.
That motivation was the fuel behind our vision, leading to an experience that honed in on a core UG2 value: people. The theme? The Recipe for a Great Partnership.
“Just like a cherished family recipe, a successful partnership requires the perfect blend of ingredients, including trust, expertise, and commitment,” explains Kat Luce, UG2’s Vice President of Marketing and Communications.
“UG2 has spent years perfecting the recipe for exceptional facility services and that’s created lasting relationships that feel like family. What better way to celebrate that than with something warm, personal, and unexpected?”
A recipe is more than the sum of its ingredients, though that’s certainly an important component. It also requires care and consistency to make it meaningful. “That’s exactly how we approach our partnerships,” adds Kat.
Straight from the UG2 Kitchen
The UG2 team brought this creative concept to life through recipe themed giveaways, interactive booth games, and a thoughtful exhibit design that reflected our values and our people.
“We set our sights on making the most of the space—not just visually, but experientially,” Kat shares.
“We wanted to create a welcoming place that invited conversation,” says Sayne Jimenez, Brand and Creative Services Specialist at UG2. “So many booths offer the same thing—raffles, trinkets, a quick sales pitch. We focused on creating opportunities for real interaction.”
Those opportunities included a memory game that gave attendees the opportunity to win on-theme prizes like aprons, oven mitts, measuring spoons, and snack packs, plus the grand prize of a $250 William Sonoma gift card.
Additionally, visitors got to takeaway recipe cards with information on UG2’s services, plus a limited edition UG2 cookbook featuring recipes submitted by team members from across the country.
Recipes include Grandma Dee’s Homemade Meatballs from the Lanzillo Family and Empanadas from UG2’s Operations Manager, Tom McKenna. Of course, there are also desserts and drinks like the made-for-a-party Coquito from Iris Stymiest, Director of Payroll Benefits & Employee Services.
“We loved seeing people flip through the cookbook and realize it wasn’t just a gimmick,” says Lauren Lanzillo, Vice President of Culture and Community. “It was a genuine celebration of our culture and the people behind UG2’s success. That authenticity resonated.”
This blend of a traditional booth with an innovative take on conference interactions reflects UG2’s belief that great partnerships start with genuine connections—and a little fun doesn’t hurt, either.
“The feedback we got over and over again was that we were a breath of fresh air,” Lauren adds.
Community: A Key Ingredient for Success
From the clean, eye-catching graphics to the thoughtful take-home cookbook, every detail of the campaign reflected UG2’s philosophy: when you focus on people, great things happen.
So, while we were busy serving up conversation and connection on the expo floor, we also took time to give back.
Members of the UG2 team joined fellow BOMA attendees in assembling Summer Survival Kits for Bridge Over Troubled Waters, a Boston-based nonprofit supporting at-risk youth.
“Community is a key ingredient in everything we do,” says Rob Berger, Senior Director of Engineering. “Participating in this service event was a powerful reminder that real partnership means showing up for the people around us.”
We’re proud of the services we provide—but just as proud of how we provide them. That human connection is what drives lasting partnerships.
A Timeless Recipe with Room for Evolution
Just like a recipe that evolves as it is handed down generation to generation, the Recipe for a Great Partnership doesn’t end with the conference. The fundamental ingredients remain the same but may be combined in new ways to meet current demands.
“BOMA International gave us the chance to showcase what makes UG2 different,” says Kat. “Now we’re excited to carry that momentum forward with a fresh way to tell the UG2 story—and it’s one that clearly resonates.”
While we’re proud of our participation at BOMA, we’re even more proud of what it represents: that great service starts with great people, united by shared values and driven by a commitment to excellence.
At UG2, that’s our recipe—and we can’t wait to keep serving it up.
UG2 is a perennial platinum sponsor of The Outstanding Building of the Year (TOBY) and Industry Awards for BOMA Boston.
How Facility Services Teams are Successfully Integrating Artificial Intelligence
UG2 operates at the forefront of innovation and technological advances in the facility services industry, and our experts have been leading the way in understanding how artificial intelligence can propel our work to new heights.
Matthew Deehan, who manages UG2’s facility management solutions team, recently published a five-step readiness guide in Facility Executive to help organizations prepare for AI and make the most of its potential. The article comes at a critical juncture—extraordinary change is on the horizon, and the time for leaders to act is now.
AI Done Right: The 5-Step Readiness Framework outlines a number of components that are key to a successful AI adoption strategy:
1. Create a stakeholder task force. The immediate need is to establish a cross-functional task force. This initiative should be led by facility managers but should include active representation from all critical parties. That means involving: the facility services experts who know the day-to-day operations AI can impact; IT personnel who are positioned to weigh in on technical, informational security, and data integrity concerns; representation from your legal team to speak to compliance and governance; and external facility services provider partners who oversee service delivery.
2. Establish AI objectives. Because the sheer number of places AI can intersect with our work is overwhelming, the work of the task force should begin with identifying and prioritizing goals and objectives. The discussion might yield a strategy that emphasizes, for example, decreasing costs by a certain percentage, reducing unplanned equipment downtime and lengthening life cycles, and enhancing tenant relations with tools that improve communication and response times.
3. Assess your data availability and integrity. Facility services, like most industries, is increasingly data driven—but ensuring that you are using data to your greatest advantage can be a challenge. Leveraging the tools and capabilities that allow you to access useful data in real time requires intention, expertise and a strong data-strategy foundation that answers questions like whether you have adequate sensors in operation, what it would take to budget for the most strategic data collection, and how to approach and implement related training for employees.
4. Prioritize security. Leaders and decision makers must take a security-first approach to AI. This involves a wide range of issues, from establishing policies to protect confidential company information and individuals’ personal data and ensuring vendors’ data is protected to developing and updating data privacy training for all employees and ensuring compliance with regulations such as those dictated by HIPAA and OSHA.
5. Evaluate AI solutions as they emerge. Solutions are emerging faster than we can keep up with them. That means the work of your task force will be ongoing, and urgent. Every facility has unique needs, goals and vulnerabilities. Ensuring your approach continues to serve your organization and stakeholders will require continuous evaluation. Relatedly, the cost implications of AI implementation must be considered going forward. The cost-savings promise of AI has long term potential, but initial setup and ongoing integration will create new expenses.
While the challenges of thoughtfully planning and integrating AI can be daunting, its benefits will be transformational to the industry and may bring advances and improvements at an unprecedented pace. We encourage you to read Matthew Deehan’s full article in the December 2024 issue of Facility Executive, and we will continue to grow and share our expertise as these exciting developments play out.
Refining Specialized Services for Critical Environments
For life science organizations relying on the maintenance of highly sensitive environments, there is simply no room for error. The high stakes involved might lead some companies to believe they are better off keeping their facility services in-house. In reality, outsourcing your facility services can be one of the smartest decisions you make for your company—if you choose the right facility services partner.
What makes UG2 the partner of choice for so many leaders in life science?
- Specialization and professional certification. Unlike many of our competitors, UG2 is formally certified to clean life science environments. We also go above and beyond by maintaining the industry’s highest levels of training, education, and professional development through the robust offerings of our Training and Innovation Lab; its virtual platform allows every employee, regardless of location, to build knowledge with guidance from established experts across the country and the company.
- The correct standard operating procedures.

Building a Culture of Learning
In a time when finding and retaining talented employees is as difficult in our industry as in many others, UG2 is grateful and proud of our strong employee retention rate. We have employees stay with us as they build their careers, and who remain—or return—through life changes, family challenges, and new educational achievements.
We often talk about our people-first approach. But what exactly does that mean when it comes to creating a workforce who commit, for the long term, to us, to each other, and to our customers?
Not only does UG2 treat employees as family, but we are also a company that trusts in training and mentoring. On the institutional side, that means offering formal and robust opportunities to grow skills, build knowledge, and become subject matter experts. UG2 excels in providing organizational offerings that range from customer service training to a dedicated UG2 Development Toolkit. We have strived to differentiate our employee development experience by investing in our very own training and innovation lab. The lab’s virtual platform means we can offer ongoing training to our employees no matter where they live and work, and the flexibility means they have the chance to fit those opportunities in with their busy lives. It also allows us to capture the insights of employees from across the country who bring a whole range of expertise and share their knowledge with the same flexibility.
But building a culture of learning goes beyond what you see on paper.
The mentorship aspect is a key component of a successful program. It requires a very intentional approach of recruiting employees who will embrace opportunities to mentor and to be mentored so that they can share, learn, and pass on knowledge. The flow of information stems not just from experienced veteran employees, but also from younger generations teaching more seasoned employees new approaches, technology and ways of thinking and problem-solving.
A Harvard Business Review study found that Gen Z employees are not only our most racially and ethnically diverse generation in history, they are also a generation that brings tremendous tech knowledge to the workplace, and one which thrives when they are truly engaged through two-way communication and problem solving. It also found that this younger generation of workers does best when they can see career paths and opportunities to grow in their futures. This knowledge and research has informed UG2’s mentoring program.
This means that in a sense, everyone is a mentor. We believe that no matter how new you are to your position or to facility services as a whole, you have a unique perspective and life experience that each one of us can benefit from. That is part of our commitment to honoring difference and diversity. It also serves as a continuous reminder that the newer generation of employees are our future leaders in the making.
In the same vein, UG2 recognizes that we continuously learn from our customers. We work to become citizens of their industries and integrate and adapt their best practices and preferences into our trainings.
Finally, a successful mentorship program committed to building future leaders and excellence in customer service must spend time passing on “soft skills.” Teaching people skills that enable being able to talk to anyone, to come out of the boiler room ready to connect, has been integral to UG2’s approach and success.
An employer can establish excellent training programs, but if you manage to build a team that is engaged and willing to learn and grow and help others do the same, your efforts will go much farther—and the impact, on your business and on the next generation of talent, will be profound.
At UG2, when it comes to the core values guiding our work, we walk the walk. But don’t take my word for it. Here is a sampling of notes sent by customers expressing gratitude for the hard work and consideration our employees put into their work—and by our employees themselves sharing their appreciation for the opportunities they encounter as members of the UG2 family.

The Right Facility Services Provider Can Make a Huge Difference
When considering the move toward bringing in an outsourcing partner, the fact is that emotions can run high for in-house staff. Some might think they’re being replaced, or that an outsourcing company will bulldoze all of their carefully constructed operations procedures. Some in your organization may not even be able to articulate why they’re feeling unsettled about it, they just know it will be a change, and that’s enough to make them bristle.
We get it. And it’s crucial to find a partner that gets it and takes ownership. In a new outsourcing arrangement, experience is key to handling not just the everyday tasks, strategic initiatives, and workforce needs, but also the emotions that come along with it.
In addition to that major consideration, there are other top factors to consider when you’re assessing whether an outsourcing partner will be a good fit for you:
- Expertise in your specific industry or field, with a list of customers to prove it, and knowledge of the processes unique to your industry.
- Certifications and experience that go above and beyond the bare minimum; an outsourcing partner should have a strong emphasis on ongoing education and training.
- Well-articulated mission statement that puts customers first and establishes the outsourcing provider as a customer-centric company.
- Desire for collaboration, not replacing existing staff; “partnership” shouldn’t be a meaningless term in their marketing materials, but instead, a driving focus.
- Labor relations experience: an engaged, productive workforce doesn’t happen by accident, it’s the result of informed and proactive measures that significantly reduce the risk of labor problems.
- Alignment with existing leadership infrastructure; also, the ability to add to that leadership in meaningful ways that maximize the power of an organization’s knowledge base and strategic direction.
- Emergency preparedness protocols and response; An outsourcing partner should have a proactive mindset, rather than a shorter-term, reactive process that doesn’t anticipate changing needs.
Most of all, a partner should be exactly that: a partner. Collaboration and trust is an essential element for this, and an outsourcing provider should be able to detail the ways in which processes and procedures will be shared, not replaced.
At UG2, we see each customer engagement as an opportunity to share our knowledge and expertise, and also to maximize the resources already in place, so that customers can develop strategies that are proactive and meaningful.
Outsourcing facility services isn’t about bringing in more subcontractors and dealing with the potential headaches that come with that move. It’s about creating a partnership that brings both short-term benefits and long-term advantages in a way that advances efficiency, strategic thinking, workforce productivity, and mission-driven initiatives.

Get answers to some of the most-asked questions
Lately, we’ve been getting numerous questions from our customers about the use of ultraviolet (UV) light and whether it acts as a sterilization or disinfection technique that’s worth pursuing. Here’s some information that should clarify how UV is used—and when it’s not appropriate.
What is Ultraviolet?
Ultraviolet (UV) light is one form of electromagnetic energy produced naturally by the sun. UV is a spectrum of light just below the visible light and it is split into four distinct spectral areas – Vacuum UV or UVV (100 to 200 nm), UVC (200-280 nm), UVB (280 to 315 nm) and UVA (315 to 400 nm).
What is Ultraviolet C?
The entire UV spectrum can kill or inactivate many microorganism species, preventing them from replicating. UVC energy at 253.7 nanometers provides the most germicidal effect. The application of UVC energy to inactivate microorganisms is also known as Germicidal Irradiation or UVGI.
UVC exposure inactivates microbial organisms such as bacteria and viruses by altering the structure and the molecular bonds of their DNA (Deoxyribonucleic acid). DNA is a “blue print” these organisms use to develop, function and reproduce. By destroying the organism’s ability to reproduce, it becomes harmless since it cannot colonize. After UVC exposure, the organism dies off leaving no offspring, and the population of the microorganism diminishes rapidly.
Ultraviolet germicidal lamps provide a much more powerful and concentrated effect of ultraviolet energy than can be found naturally. Germicidal UV provides a highly effective method of destroying microorganisms.
Does UV light sterilize everything in an area?
First, a note on definition. Disinfection and sterilization are both a type of decontamination process, but differ in terms of method and result. Disinfection reduces harmful microorganisms, while sterilization kills all microorganisms. This is an important distinction, because unless we’re in a scientifically controlled environment, we’re not able to sterilize, only disinfect. That said, reducing harmful microorganisms is crucial, and UV light is an effective component in an overall disinfection strategy.
How is UV used in disinfection of a building?
Most likely, you’ve seen images or video of UV disinfection on the news since it’s being used right now in places like airline cabins and subway cars. Those systems are different than what’s used in HVAC air-handling equipment and water filtration, mainly because there are major differences in applications.
Ultraviolet light for germicidal disinfection (UVGD) has one major limit. UV only works in its light path and can be blocked by objects creating shadows. Inline water filters and air handlers work well because we move the particle being disinfected directly across the light path for a specific amount of contact time. That light needs to be in the UV-C wavelength to be effective — blacklights, on the other hand, have a UV-A wavelength and are not effective because the energy won’t be strong enough to penetrate the lipid skin of a cell.
This issue can be minimized by using multiple UV bulbs to generate UV irradiation from different angles, but that would take a lot of time in one small space. Another solution is to use larger robotic disinfection systems. These systems are being used in hospitals and medical research where the cost of the robot units is offset by the potential lost revenue of hospital acquired infections (HAI) if they weren’t used. These robots may be less practical elsewhere, but that doesn’t mean some degree of UV disinfection won’t be helpful.
What about the handheld UV wands now in the consumer market?
These are nice tools, but effectiveness and practicality limitations do exist. First, the light must be hand-waved for a specific length of time over the surface and through the air of the inanimate object being disinfected. This is time consuming, and subject to a lot of human error, whereas electrostatic chemical disinfection can often be completed in a fraction of the time with the same efficacy and cost.
Second, these bulbs often contain high amounts of mercury and can present safety and disposal hazards. Finally, it’s not clear whether these wands on the market are calibrated to the right wavelength all the time. Some may be just blacklights, which do nothing to damage DNA, so that means it wouldn’t be strong enough to penetrate the nucleocapsid of a virus or envelope of other pathogens. Consumers need to do their research when purchasing these tools.
What’s the benefit of installing UV-C lighting in water and air systems?
This is the single point where we control a free-floating molecule and it is for this reason, it may be the most practical application for non-healthcare facilities. Air and water are fluids, we can push or pull those fluids in a very controlled way past a contact surface and use that surface to apply the light.
These systems must be engineered with the proper fixtures, placement, safety, and lamp type based on criteria such as the volume, velocity, humidity of the space, design temperatures, use of space, control surfaces, and a host of other considerations. The benefit is that while air is moved across the filter media, ongoing disinfection occurs.
As buildings become more efficient—in ongoing efforts to save cost and reduce the carbon footprint—newer systems are designed to reuse and recirculate more of that air repeatedly through economizers and return air mixing boxes. This makes inline filtration and disinfection a more important component in the overall effectiveness of a healthy facilities management strategy to reduce harmful pathogens and one that UG2 considers with customers when discussing Engineering4Health as part of our UG2 ReNewSM strategy.
What else should be in place for an efficient disinfection system?
Light from any UV-C filtration in an air handler or water system cannot reach the hard surface in the room. For this reason, this type of system should only be employed alongside other engineering controls and human behaviors as components in a holistic facilities management strategy.
These include an effective janitorial program, a properly trained staff using the correct personal protective equipment, correct social distancing, and well-maintained room pressure and/or isolation based on room occupancy and potential infection levels. And of course, proper hand hygiene.
