I joined GS1 UK in September 2012 as a Solutions Consultant to support our members while implementing GS1 standards and create new services for them. Currently, I am working on the Perfect Order project – To deliver a robust retail standard with a clear focus on ‘right first time’ that is adopted as industry best practise, removing significant avoidable cost from the supply chain and delivering benefit to the consumer.

I joined GS1 UK in September 2007. My main focus is to work with the healthcare sector to support the NHS to adopt GS1 standards – enabling it to make substantial savings and improve patient safety by accurately identifying patients, medicines and medical equipment.

Before joining GS1 UK, I was the Sales Support Manager for Avery Dennison, heading up a development team.

I’ve contributed to three pieces of work that are now required standards for the NHS.

Dave Weatherby David Weatherby

Business Consultant

I joined GS1 UK in 2004 where I work with our members to help them understand how GS1 standards can lead to real benefits for themselves and their trading partners. I’m currently focusing on healthcare, working with the Department of Health, HSCIC and NHS Trusts to support them to implement GS1 standards – which are now a mandatory requirement.

Before joining GS1 UK, I gained over 25 years’ experience in operational research. I also managed the development, support and marketing of computer-based information and communications products and services, for companies including Reuters and Cadburys.

I’m proud to have led the introduction of GS1 standards for RFID (Radio Frequency Identification) to the UK and Europe as Manager of the EPC Global European Adoption Programme.

Marlon Chedumbrum Marlon Chedumbrum

Business Consultant

I have been working at GS1 UK since 2015. I liaise with NHS Trusts to help understand and implement GS1 standards as mandated by the Department of Health. It is a large implementation for Trusts to undertake; through consultation we work together to create a strategy for exploiting GS1 standards to improve patient safety and patient care.

Prior to working at GS1 UK I worked in various Trusts across London and Hertfordshire as a Senior Manager, defining strategy, managing departments, implementing change management and building commercial awareness.

Outside of the NHS, I have worked in the US and Europe as Principal Consultant for a variety of consultancies across Financial, Construction, Private and Public sectors. When not at work I spend a lot time with my 3 year old Akita. He is super smart and equally stubborn and difficult to train. Great to see that he’s adopted 50% of my traits!
