Steele is currently a logistics and ordering customer services adviser but has held numerous roles since he joined the company in 1984.
Originally recruited in the quality control department for vegetable seed to oversee the testing of germination rates, he moved to the young plants business in 1987.
Steele commented: "I have seen many changes over the years. There has never been a dull moment. It is the people with whom I have worked who have kept me here for so long."
During his tenure at Syngenta Steele has witnessed the shift to computerisation in the ordering process, which saw productivity grow from 10,000 boxes per week in the late 1980s to 70,000 now. He also followed the company south when it relocated its UK offices earlier this year, moving from Lancashire to Cambridge.
UK and Ireland flowers business manager James Clovis said: "Having worked with Kevin at the Halsall offices, I was delighted when he agreed to relocate with the business. The knowledge that he has brought to the newer members of the team has been immense and we all appreciate the experience that he brings."
