"I worked with Lee during his time at International Timber as a Continuous Improvement Manager. From day 1 Lee and I got on great as we are both of the same mind-set always looking to find how we can improve processes and practices. Lee is very approachable and always willing to listen no matter if you an operator on the shop floor or the CEO, the standard of his work was always extremely high in particular his presentation work always impressed me as it was very easy to understand what point he was making"

"I have known Lee for around three years now and I must say his passion for lean is infectious. My desire for change management was high before meeting Lee, but upon meeting and working with Lee I can say he helped me reach a different level. His ability to be honest and then offer ways to help is 100% the right approach. From our time working together he has helped me develop confidence as a person and a leader - he has also helped me in delivering a number of improvement projects over the line that have helped developed me and the team - most notably TPM, visual management boards, 5S training and WOM. Lee would be a more than welcome addition to any business in any role as he has the ability to connect with all the key stakeholders within the business"

His dedication, focus, and proactive attitude made him an asset to the team and a role model for others. Lee maintained an excellent timekeeping record and regularly volunteered to support business objectives beyond his core responsibilities. His behaviour and professionalism stood out, and he was one of the most pleasant and polite individuals I’ve encountered in my 26 years at Airbus.

During our time together, Mr Bellis proved vital to the improvements of our sites 5S, VSM & KANBAN where he personally made several changes in line with our business needs. Throughout this challenging period, I worked closely with Mr Bellis as there was a high amount of change management involved to ensure the process remained successful and despite being new to our site, Mr Bellis remained professional to all staff encountered and quickly built a very good rapport with my employees. The work conducted by Mr Bellis is still evident at site despite and is continually evolving as our business model changes. I can’t speak highly enough about Mr Bellis and his work ethic – he will be a success wherever he works and would be pleasure to work with again.

Lee has been instrumental in the implementation of KANBAN systems throughout the factory as well as other JIT and Lean Manufacturing methods. Lee gives every task he is given his full attention and effort and has never failed to deliver. I would have no hesitation in recommending Lee to any future employer.

I was fortunate enough to work closely with Lee on several projects during our time at Alliance Healthcare. He's an excellent communicator - approachable, professional, and able to explain complex Lean principles in a way that resonates with people at all levels of the business. Lee played a key role in guiding our team on a Continuous Improvement journey that delivered real, lasting efficiencies. Lee would be a valuable asset to any business looking for a personable, knowledgable expert in CI and Lean principles

I had the pleasure of working with Lee Bellis during his time supporting our site on the maintenance work order management system. Lee’s expertise and guidance were instrumental in helping us improve and simplify our processes. He provided valuable advice and took the time to consult with our team, ensuring we focused on the key elements necessary for an effective system. Lee’s collaborative approach, openness to our ideas, and willingness to share his own insights made a significant positive impact. The improvements we achieved together have had a lasting effect on our site’s efficiency and effectiveness. Lee’s presence and contributions are truly missed. He has left a successful footprint here, and his work continues to benefit our operations.

I can’t recommend Lee highly enough. We have partnered with him for years in developing innovative Visual Management solutions, and his expertise in lean principles, alongside these solutions, has consistently helped his clients operate more efficiently and drive CI. Lee is also just a top bloke with a positive attitude to his profession which makes working with him a pleasure.
