Jonathan grew up near Gainsborough and went to Queen Elizabeth’s High School. He joined Lindum at the age of 21 and after completing his studies, he became a commercial manager and then a general manager at Lindum Waste in Saxilby.

He switched to Lindum York in 2014 and has led its development into a company with a £30 million turnover, 56 employees and a growing order-book and reputation.
