A company with an open door

John O’Conner is a privately owned company with people at its heart. We are not hide-bound in hierarchy; if you need to speak to one of the company’s Directors, the MD, or even the Chairman, it’s a matter of picking up the phone – or walking into the company offices.

Founder John O’Conner’s down-to-earth, entrepreneurial spirit forms the core of our company culture. We have evolved a practical, systems-driven approach, making us nimble on our feet, ready to adapt to new challenges and methodologies and quick to respond to problems on the ground.

Chat to any of our management personnel, from the Chairman and MD down, and you’ll find they are horticulture people through and through.

Unlike almost all of our competitors, our directors involve themselves in the contracts and attend monthly meetings with clients. That close link between management and staff ‘on the ground’  is key to John O’Conner’s continued success.

Why clients stay with us for the long term

Many of our contracts are in their second or third term. Why? Part of the answer is in our externally verified systems which help deliver continuous improvements, resulting in financial savings, increased workforce productivity, greater sustainability and customer satisfaction.

Who is this John O’Conner guy?

John O’Conner is a ‘large as life’ person who still shapes the vision of the company.

Originally from a farming background in Surrey, he moved to Essex at the age of 18 and joined what was then the GPO, training as a telephone engineer.

After relocating to Stevenage as a newly-married man in 1961, John started by doing gardening jobs in his spare time. On hearing that Bedford GPO used a contractor for grass-cutting, John submitted his own bid, and secured his very first commercial contract.

Entrepreneur with a spirit of adventure

Early success fuelled his ambition and he took on more grounds maintenance work, targeting local authorities. The business grew steadily and John left the security of his GPO position and started employing people to help him.

John purchased land in Welwyn where he built the machinery workshops. Shortly after, he purchased a nearby office facility. Although grown in size, both facilities still serve the company today.

John has always had an active interest in nautical history and is an acknowledged authority on William Bligh, of Mutiny on the Bounty fame. In 2005, he visited the Pitcairn Islands on a research trip and was marooned there for five weeks by heavy storms.

Against local advice, John convinced the captain of an oil rig boat to take him on a three week trip to New Zealand, from where he could fly home.

On his return, he received a call from a friend who needed help bringing his 50ft yacht from Boston, Massachusetts, to the UK. John flew out, became the third crew member, and working shifts of three hours on, six off, brought the boat under sail across the Atlantic.
