About Us

We’re People People

With offices in Naas, Co. Kildare and Horgan’s Quay, Cork, Clark is strategically positioned to support organisations and talent across Ireland. This dual-location model reflects a considered, long-term growth strategy—one that combines proximity to Ireland’s largest employment centres with deep regional insight. From permanent and contract recruitment to temporary solutions and executive search, Clark delivers tailored, relationship-led recruitment nationwide.

“Our presence in both Naas and Cork is very deliberate,” says Stephen Farrell O’Callaghan, Managing Director.
“Naas places us at the heart of the Dublin commuter belt, while Cork anchors our commitment to the Munster region. Together, these locations allow us to work closely with clients and candidates, while maintaining a truly national perspective.”

Clark’s Naas headquarters provides immediate access to Dublin and the surrounding commuter towns across Kildare, Meath, Wicklow, and beyond. This location enables close engagement with Ireland’s largest concentration of employers across professional services, financial services, technology, life sciences, and indigenous enterprise, while remaining connected to talent nationwide.

“The Kildare office gives us daily proximity to Dublin-based organisations and the wider Leinster commuter network,” explains Sarah Mortimer, Director of Recruitment.
“It allows our consultants to build strong, long-term relationships with clients and candidates, while responding quickly to changing hiring needs across permanent, contract, and temporary markets.”

The establishment of Clark’s Cork City office at Horgan’s Quay represents a natural extension of this strategy. Cork offers a compelling mix of talent availability, economic momentum, infrastructure, and quality of life, making it a critical growth hub for the Munster labour market and a key counterbalance to Dublin’s dominance.

“Our decision to open in Cork reflects both client demand and the strength of the region,” says Stephen Farrell O’Callaghan.
“Cork is not just a regional city—it’s an international business destination with a mature employment ecosystem and long-term growth potential. Being on the ground allows us to serve Cork-based clients with greater responsiveness and insight.”

Prime city-centre connectivity was central to the Cork location choice. Situated immediately beside Kent Train Station, the Horgan’s Quay office offers seamless regional and national access, supporting engagement across Cork city, the wider county, and the Munster region, while maintaining strong links to Dublin and Leinster.

Cork’s deep and diverse talent pool aligns strongly with Clark’s multi-disciplinary recruitment offering. The metropolitan area supports a population exceeding 415,000, with more than 40,000 full-time and part-time students across business, technology, engineering, life sciences, and professional services.

“What stands out in Cork is the breadth and quality of talent,” notes Sarah Mortimer.
“From early-career professionals coming through the universities to highly experienced specialist and executive candidates, it’s a market that supports permanent, contract, temporary, and leadership hiring at scale.”

Cork’s long-standing success in attracting global investment and scaling indigenous businesses has created sustained demand for specialist, professional, and executive talent—areas where Clark has deep expertise.

The region’s quality of life plays a critical role in long-term talent attraction and retention. As a former European Capital of Culture and a consistently ranked European destination city, Cork offers a vibrant cultural scene alongside access to coastal, rural, and urban living.

“Quality of life is no longer a ‘nice to have’—it’s central to recruitment and retention,” says Sarah Mortimer.
“Cork’s lifestyle appeal strengthens workforce stability for our clients and supports long-term hiring success.”

Strong residential and regional infrastructure, including significant housing development and rail connectivity to commuter towns such as Cobh, Fermoy, and Mitchelstown, broadens the available talent catchment—mirroring the commuter dynamics that underpin Clark’s Leinster presence.

Cork’s recognition as a leading European destination for foreign direct investment, alongside its ranking among the top small European cities for economic potential and business friendliness, reinforces its position as a growth-oriented, internationally connected business environment.

As a university and research-led city, anchored by University College Cork, Munster Technological University, and world-class research centres such as the Tyndall National Institute and the Nimbus Research Centre, Cork continues to drive innovation-led employment and specialist recruitment demand.

Strategic Fit for Clark

Operating from both Naas and Cork enables Clark to:

Support Dublin and commuter-belt clients with speed, proximity, and insight
Deliver on-the-ground recruitment expertise to Cork and Munster-based organisations
Access broader regional and national talent pools
Align with regions demonstrating sustained economic growth, innovation, and inward investment

“At Clark, we believe recruitment is about more than placing people – it’s about helping organisations thrive,” concludes Stephen Farrell O’Callaghan.
“Our style is professional and approachable, with a warm, expert tone that’s never transactional. Across every platform—from job adverts and candidate outreach to employer branding and executive search—we tell a consistent story: hiring isn’t one-size-fits-all. By taking a holistic, human-centred approach, we help our clients build stronger teams and achieve long-term business success.”
