Haleon building a space all its own at The Park in Berkeley Heights

The basics:

• Haleon signed one of New Jersey’s largest office leases of 2025 at The Park
• Company will relocate more than 700 employees to Berkeley Heights
• The 78,000-square-foot headquarters will span three floors with modern hybrid workspaces
• Project reflects Haleon’s long-term investment in New Jersey, workforce strategy

Haleon’s new lease agreement at The Park in Berkeley Heights represented one of the state’s largest office deals of 2025. The decision to relocate its more than 700 employees within New Jersey reflects the company’s long-term investment in its workforce and workplace strategy.

During a March 25 construction kickoff event, Nathalie Gerschtein, CEO USA and president of North America at Haleon, described the new U.S. headquarters as “kind of” a big deal.

Capped with a champagne toast and tour of the future space, the celebration highlighted why – and how the characterization applies in more ways than one.

“Since we spun off from GSK, about four years ago, we’ve been on that transformative journey to become a best-in-class CPG and really the leader, the independent leader, when it comes to consumer health care.

“And this new office is the physical point of that transformation,” Gerschtein said.

The move also marks a win for The Park. It comes as The Connell Co. celebrates 100 years in business and its $500 million investment to transform the work resort’s 187 acres into a live-work-play destination for its tenants and the public.

Campus life

The company will move eastward along Interstate 78 from its current base on Liberty Corner Road in Warren to 400 Connell Drive (RT400) in Berkeley Heights.

“I like the idea of being part of a campus,” Gerschtein told NJBIZ. “There are other companies – you can really build a business community and I think it makes a difference.”

She contrasted that with the isolation of a lone office building (like Haleon currently occupies) or even a downtown/urban location. Though those kinds of spaces have attracted – and helped keep – other major health companies grounded in the Garden State. Haleon’s move to The Park marks one of the latest endorsements for New Jersey in that regard. Sanofi moved into its bespoke building in Morristown last year.

Earlier in 2025, consumer health company Kenvue celebrated its new headquarters in Summit. The debut followed that consumer health company’s separation from Johnson & Johnson. Since, Kimberly Clark Corp. has advanced plans to acquire Kenvue in a nearly $48 billion deal. And in 2023, Merck consolidated its workforce at a reimagined headquarters space in Rahway.

“This move … is a commitment to Berkeley Heights and New Jersey,” Isabel Valente noted during her remarks at the construction kickoff. Valente leads workplace solutions for Haleon North America and the new headquarters project. “We’re going to be here for a while, and we’re really excited about the partnership and the community engagement that we will see here,” she said.

1.4B customers served

With a global headquarters in the U.K., Haleon operates in 170 markets around the world and serves 1.4 billion customers. Its portfolio spans six categories: Oral Health, Vitamins, Minerals and Supplements; Pain Relief; Respiratory Health; Digestive Health and Therapeutic Skin Health.

Included in the package are a variety of brands, such as Sensodyne, Advil, Aquafresh, Centrum, Emergen-C, Robitussin, Theraflu, Tums and others. The company launched in 2022, after spinning off from GlaxoSmithKline.

Commenting on Haleon’s fiscal year 2025 results in February 2026, CEO Brian McNamara described the period as an important year for the company.

“We introduced our Win as One strategy and are already making good progress. Our brands again proved their resilience, and we continued to outperform the market, with 60% of the business gaining or maintaining share this year.”

Haleon reported 3% organic revenue growth to close out fiscal year 2025. McNamara noted the figure missed medium-term expectations, thanks to a weak cold & flu season and lower consumer confidence in the U.S. Nevertheless, “We delivered strong gross margin improvement and double-digit organic profit growth, combined with strong cash generation.”

Looking ahead, Haleon remains confident.

“While the consumer environment remains challenging near-term, we are even more focused on driving category growth and increasing our market outperformance,” McNamara said.

‘For Haleon, by Haleon’

That confidence is also reflected in the investment at The Park. The old GSK Consumer Healthcare office currently serves as Haleon’s U.S. base. Gerschtein described the new office as “a space for Haleon designed by Haleon.”

With the end of its lease approaching, the company told NJBIZ last August it used the opportunity to find a campus that offered the best fit for its office needs and the most amenities for its employees. From the murmurs among tour participants during the March fete, that goal appears to be hitting its mark.

CBRE represented Haleon in its 10-year lease in Berkeley Heights. HLW provided architecture design, Unity Construction Services Inc. is handling construction and Gardiner & Theobald  serves as project manager.

Delivery is expected in the fourth quarter of 2026.

The new 78,000-square-foot space will span three floors connected by central staircase to promote engagement. Its layout emphasizes efficiency to accommodate a flexible, hybrid work experience; strengthen team connections; and provide modern coworking and meeting areas.

Valente said the vision was clear from the start. “Everyday health is humanity, and we really need to achieve that together as an organization. So, we needed our space to be designed for our people. For how we work, and also for the consumers that we support in this region,” she said.

The forthcoming space will also include the Shopper Science Lab, featuring immersive, 360-degree simulation and consumer co-creation spaces. The areas will provide space to build on the company’s consumer-focused innovations, along with its partnerships.

The company highlighted the potential for low-carbon commuting – The Park will cut the ribbon on its first apartments this year – and accessibility along with “responsible operations” at the campus. It highlighted sustainability features including EV charging infrastructure, on-site solar canopies and a bikeshare program.

Additionally, Haleon cited modern mechanical systems and site planning at the Union County property as supporting long-term operational efficiency. That consistency is important to employers looking to craft not just an amiable, but elevated work experience.

In promoting its new base, Haleon referenced the hospitality forward experience The Connell Co. has established at The Park under its RoundTable Workspace banner. Describing it as the clear choice, Valente said The Park delivers modern infrastructure and a built-in amenity base.

Coming together

In his remarks, The Connell Co. Executive Vice President Shane Connell said the addition of Haleon marks a milestone for the company, too. At 100 years old, the family-owned business has covered five generations, so far. “We’ve been working on this park for 40 years and we are trying to help companies like Haleon provide a better work solution,” Connell said. “And to us, that is about a work life balance and people forward.”

Following a $100 million capital improvement plan, The Connell Co. introduced RT Workspaces at The Park last year. In May 2025, it announced nearing full occupancy across the available 1.5 million square feet of office space. The office areas offer flexible floor plates and build-to-suit opportunities supported by full-service concierge, quality dining options and wellness programming.

Class A building RT400, where Haleon will reside, totals 260,000 square feet with a location adjacent to The District, a retail and residential component coming to The Park. That project will add five new buildings, including more than 300 apartments and over 190,000 square feet of commercial space.

The campus already features a Starbucks, Lifetime Fitness, walking and jogging trails, coworking space and hotel. Currently an Embassy Suites, Connell told NJBIZ there are plans to rebrand the hospitality offering to sync up with the rest of The Park.

In addition to the benefits on-site workers reap, Gerschtein noted the mix and hotel also help support a traveling global workforce.

Connell highlighted connection as a “valuable piece of the work experience. Collaboration, productivity, but then also a place of purpose.”

Employee experience

Communal spaces at The Park help to extend company footprints and create active spaces for engagement. And the campus is further working to achieve connection in a disconnected age by leaning into trends that turn back the clock.

“We’re doing a coffee shop that’s anchored by books. We’re doing a steakhouse that’s anchored by a clubroom that’s got duck bowling and pool tables and billiards. We have a Bathhouse coming here. [The trendy Brooklyn-based spa will bring its first New Jersey location to The Park],” Connell said. “And we just want to thank you for choosing New Jersey and choosing us as your place.”

Team members pointed to the convenience (and excitement) of the mixed-use environment. “We wanted a place that can really be a neighborhood for the employees,” Gerschtein told NJBIZ. “A place where it feels good to live; it supports the work they want to do. It’s a job, but it [the campus] has a lot of other opportunities.”

Opportunity is an apt word to describe the transformation taking place at The Park. And 2026 looks to be a big year for delivery on that promise. Among impending milestones are opening doors to those first residential units and the fall debut of its Emberside Brewery. Looking ahead, The Park recently received approval to add a day care center to the property, General Manager of Hospitality Sharon Lammens said. She led guests on through RT400 and Haleon’s upcoming office.

As part of the tenant experience, Lammens provides onboarding and outreach to occupants’ employees to avail them of all The Park offers. There’s also a dedicated app to keep tenants in the know about upcoming events or information.

During the tour, she noted the experience for Haleon employees includes memberships paid for by the company to on-site gym Fieldhouse.

Other companies recently joining the roster at The Park include Tonix Pharmaceuticals, Kennedys Law LLP and Blackstone. Fiserv, Aon, Samsung and more also occupy space.

The steady stream – and limited remaining office space – underscore the kind of workplace Haleon is betting on as it invests in its workforce and long-term growth. “Our goal is to basically bring the city to the suburbs … everything you get in New York City is what we’re trying to create here,” Connell told NJBIZ last year. “We’re trying to create a 20-minute neighborhood where everything you want or need is within a 20-minute walk. The retail and restaurant concepts, outdoor parks, all those type things … we’re bringing to New Jersey and it’s part of that workspace offering.”
