William Reid is a subsidiary of Denholm Logistics.
Denholm Logistics is part of the J. & J. Denholm group of companies, which can trace its origins back to 1866 when the first business, a ships agency, was founded by James Denholm.
James was joined by his younger brother John in 1869, when J. & J. Denholm was formed and the company is still controlled by John's descendants today. The group has since diversified and now has four main business streams: shipping, logistics, seafoods and industrial services.
