The J-Flex Leadership Team

J-Flex continues to invest in the development and empowerment of its people, who are the most respected in our sector through their technical expertise.

John Kirk


John co-founded J-Flex in 1984 with Jill Kirk.

Retford born-and-bred, John spent 15 years working in the town’s iconic Northern Rubber Works, starting out as a rubber technologist before progressing and eventually occupying the role of Marketing Director.

Since starting J-Flex, John has played an active role in developing new products and markets and has been the driving force behind our export success, regularly visiting customers throughout Europe and further afield.

In his role as Chairman, John now oversees the research and development side of the business.

Sam Kirk

Managing Director

Sam joined the business in 2015, heading up the Marketing Department and was then appointed Managing Director in May 2018. Sam graduated from the University of Lincoln in 2008, and spent ten years working in the media industry before joining the family business.

In 2018 Sam developed and implemented an ambitious new Vision and Company Plan that has provided clear focus and direction and has seen the business earn recognition at the Midlands Family Business Awards and the North Notts Business Awards, where J-Flex were crowned Company of the Year 2019.

Phillip Wright

Finance Director

Phillip is one of J-Flex’ longest serving colleagues having joined the business in 1994 as Management Accountant.

Phillip was appointed Finance Director in 2018 and now oversees our financial strategy and governance, as well as acting as a mentor to departmental colleagues. Phillip also plays a key role in driving forward our IT strategy and systems.

Phillip is a long-suffering Arsenal fan, whilst his passion for cycling saw him bike from Lands End to John O’Groats in all in the name of charity!  It was a remarkable feat and one that Phillip should be extremely proud of, as we are of him.

Lance Bradley

Commercial Director

Lance joined J-Flex in 1998 as an External Sales Executive, developing relationships with a wide and loyal client base – many of whom are still customers today! 

Following a number of years “on the road”,  Lance returned to the office and was appointed Commercial Manager.

Now our Commercial Director, Lance is responsible for working with key clients on special projects, leading and driving our internal external sales functions and helping shape our future growth.

Les Shaw

Operations Director

Prior to joining J-Flex in 2004, Les held a number of senior management and board positions with multi-national logistic and distribution companies.

In his role as Operations Director, Les oversees our Warehouse, Production and Quality functions. He regularly visits key suppliers in the UK, mainland Europe and Asia.

A sports enthusiast away from the office, Les enjoys cricket and rugby union, although now only as a spectator since his playing and coaching days are over.

Neil Duckmanton

Marketing Manager

Neil joined J-Flex in November 2018 to head up the Marketing department.

Prior to joining J-Flex, he was founder of award-winning Nottinghamshire design agency, Upbeat Design, and before that was the Senior Creative and Design Studio Manager at Rich Designs. 

Bringing a wealth of creative flair and experience to the business, Neil has worked alongside J-Flex for many years providing graphic design, web design and print services.

When not at work he can usually be found either playing his drums, in his work shed, visiting a car event or watching a movie.
