"Cadarn services are highly recommended to anyone looking for an experienced quality/reliability professional. Greg combines speed with quality in his deliverables and has contributed greatly to a number of successful product qualifications.

He thinks outside the box and is able to discern the ‘Musts’ from the ‘Nice-to-haves’ when it comes to developing efficient and effective qualification strategies. He has also supported us in building internal competences in our quality/reliability department with tutoring sessions. 

He reports regularly on the status of his activities, available budget and is generally a very pleasant person to interact with. A highly recommendable and genuine quality and reliability ‘Swiss army knife’"

Peter Hoppenbrouwers, Head of Quality, Sciosense B.V.

In my working relationship with Greg I can quote successful Quality systems certifications as well as numerous successful product development projects, including highly innovative automotive grade developments.

Greg’s excellent technical expertise, efficient and effective working style and strong communication skills makes a difference. I can but highly recommend.” 

Michael Rogers, Senior Director Quality, ams-OSRAM AG


"I have worked with Greg for a number of years now, and he has successfully guided two businesses through ISO9001 certifications, which required the development of the Quality Management System from scratch, and associated business processes and systems.

He has also been pivotal in developing and executing our product qualification plans, and managing all aspects of product reliability.


He has a unique way of developing the Quality philosophy in organisations, so that he gets management team buy-in as they see the value of what we are implementing. He has an excellent attention to detail, is focused and determined, and always delivers. I cannot recommend him highly enough".
