Previously, Gal built a 23-year career at UPS, where he held senior leadership positions across Operations, Finance, and Sales, with both domestic and international assignments in Europe and the Middle East.

Jeff McCorstin is the Chief Executive Officer of Delver Agents, HAF and Swift Marine, a position he assumed in March 2025 after serving as a Strategic Advisor to GHK Capital, the private equity firm that acquired HAF in 2024. He also serves on the group’s Board of Directors, where he continues to provide strategic vision and expertise in business transformation.

With a distinguished career of more than three decades at UPS, Jeff held leadership roles across operations, finance, engineering, strategy, and mergers & acquisitions, ultimately presiding over six global business units with full P&L responsibility. His final position before retiring in 2023 was as President of UPS Global Freight Forwarding.

Jeff’s leadership philosophy is built on the principle of “Head, Heart and Hands”: strategy and innovation (Head), inspiration and collaboration (Heart), and execution with accountability and results (Hands). He is guided by unwavering values such as integrity, transparency, inclusion, and customer focus. What drives him most is enabling teams to exceed expectations and deliver exceptional service, by providing them with vision, tools, and trust.

Outside of his professional life, Jeff enjoys spending time with his wife Kris, their adult children Courtney and Riley, and their two dogs, Stella and Lucy. He is passionate about lake life, boating, hiking, tennis, pickleball, and exploring local breweries. Deeply rooted in community, he also values time at his family’s church. His guiding mantra is “Carpe Diem” seize the day complemented by a lifelong belief that success begins with willpower and a positive mindset.

As a source of personal inspiration, Jeff often returns to this passage, which has shaped both his life and career:

*“If you think you are beaten, you are;
If you think you dare not, you don’t.
If you’d like to win, but you think you can’t,
It is almost a cinch you won’t.

If you think you’ll lose, you’ve lost;
For out in this world we find
Success begins with a fellow’s will—
It’s all in the state of mind.

Life’s battles don’t always go
To the stronger or faster person;
But sooner or later the one who wins
Is the one who thinks he can!”*

Looking ahead, Jeff is driving Delver Agents, HAF and Swift Marine toward becoming the global provider of choice for cruise and marine logistics, built on strategies that are customer-first, people-led, and innovation-driven.

After Nielsen acquired the company, she led the pivot into sports data, modernizing legacy systems to deliver advanced insights.

Since joining the group, Sheryl has led a remarkable digital transformation, evolving the technology function from outdated systems to a global team of specialists that includes engineers, project managers, and data scientists.

Looking ahead, Sheryl’s vision is to continue advancing Navigator by integrating intelligent models that reduce manual work, making the platform more interactive and empowering for both teams and clients. Beyond the product itself, she aims to expand the group’s role as a technology provider, embedding innovation as a core part of the value delivered to clients worldwide.
