After 37 years with the company, Ian St John, Sr. Vice President of Projects & Business Optimization for our European operations, is set to retire, leaving a legacy of growth, leadership and lasting impact across the organization.
Ian’s connection to the business began before his full-time career did. While studying physics in the mid-1980s, he spent several summers working in the laboratory and process areas at our Tate & Lyle Sugars Plaistow Plant, gaining early experience in the practical, hands-on problem-solving that would become a theme throughout his career.
Ian followed in his family’s footsteps when he joined Tate & Lyle Sugars, adding to a family history that spans more than 200 years of combined service to the business. That includes his father’s 44 years with the company, mainly in packaging, warehousing and on the refined sugar dock as a supervisor and manager, as well as the service of Ian’s grandfather, mother, two uncles, brother and cousins. It is one reason some colleagues still affectionately call Ian “Mr. Tate & Lyle.”
Ian joined the company full-time in 1989 as a Process Control Technologist at the former Millwall facility. It was a small site, but it gave Ian the chance to get involved in many parts of the operation, from process technology and control systems to laboratory work and supervision.
In 1994, Ian moved to our Thames Refinery as a shift production manager, taking on responsibility across a broad range of operations, including the dock, the refinery, packaging, the warehouse and dispatch. He played a key role in installing the refinery’s central controls.
One of the major turning points in Ian’s career came in 2000, when he was asked to support engineering projects and optimization efforts across Tate & Lyle’s North American operations, working at both the Domino Sugar Baltimore Refinery and the former Domino Sugar Brooklyn Refinery.
“The move to Baltimore became a real springboard for my career,” said Ian. “It broadened my perspective and exposed me to different ways of thinking and working, and I formed long-lasting friendships and connections in the business that last to this day.”
After returning to the UK a few years later, Ian managed Packaging and Operations and ultimately served as Plant Manager at the Thames Refinery. He then became Director of Tate & Lyle Process Technology (TLPT) — the company's engineering arm — where he worked with non-competing third parties and supported technical plant commissioning, business acquisitions and joint ventures around the world.
Ian’s work through TLPT took him to nearly two dozen countries across four continents, including frequent travel to Israel, Egypt and Sudan. In Israel, he played a key role in helping bring a joint venture project into operation, making 20 trips over two years to support the team in overcoming challenges to deliver a successful outcome. The project, which combined Ian’s technical expertise, commercial understanding and close collaboration with people across different cultures and markets, was one of his most memorable achievements.
Back in the UK in 2009, Ian’s responsibilities grew, and so did the scale of his leadership. Ian served as Production Director for Thames and Plaistow, Vice President of UK Production, Sr. Vice President of European Operations and, since 2023, Sr. Vice President of Projects & Business Optimization.
Over the decades, countless colleagues benefited from Ian’s guidance, his technical experience and his genuine interest in helping others succeed. Most recently, Ian led the European project engineering group, continuing to support teams and projects across the region.
For Ian, developing people has been as important as delivering projects. He takes pride in seeing colleagues grow into new roles and build successful careers of their own. His advice to those early in their careers is grounded in the same practical values that shaped his own path: Skills and education matter, but so do attitude, work ethic and integrity.
“If your work ethic is strong and you are committed, your potential here is as big as you make it,” said Ian. “Opportunities may not always be obvious right away, but in a company like this, people who make the effort do get those chances. To me, it’s always about hunger and aptitude. If you apply yourself and stay open, the right path will make itself known.”
Looking back, Ian speaks with gratitude about the opportunities he was given, the managers who supported him and the colleagues he worked alongside.
“I wouldn’t be here after all these years if it wasn’t a great company to work for,” said Ian. “I have a passion and a loyalty to this business, and a commitment to optimization and making things better, which is hopefully part of my legacy.”
That legacy will be felt in the projects he helped deliver, the teams he supported and the colleagues whose careers he helped shape.
