Meet the Director

Craig Glunt


Hello.  My name is Craig Glunt,  I am the Owner/Director of Sapphire Proficiency Testing.  I have been in the field of calibration and testing  for almost three decades, working in various roles  within calibration laboratories, to performing ISO/IEC 17025, ISO-17034 and ISO-17043 assessments.  Most recently operating as an assessor for one of the United States's premier ILAC signatory Accreditation Bodies.  

During the last decade I have gathered insight on the use and implementation of proficiency testing and ILC activities in the calibration and testing lab environment.  I want to use this knowledge to help you improve the confidence and collaboration you have  with your customers by providing solutions to your proficiency testing needs.  

Proficiency testing plays a crucial role in ensuring the accuracy and reliability of laboratory testing and calibration activities. By participating in proficiency testing programs, laboratories can identify areas of improvement and ensure that their procedures and methods are consistent with industry standards and regulatory requirements. This not only helps to prevent errors and improve the quality of results, but also helps to build trust with customers, regulatory agencies, and other stakeholders. In industries such as calibration and testing, where accurate and reliable results are essential, proficiency testing is particularly important for ensuring the safety and well-being of individuals and communities.

Overall, proficiency testing is a critical tool for maintaining the highest standards of quality and accuracy in laboratories, and is an essential component of any laboratory's quality assurance program.

I am always available for your questions or comments.  Please feel free to contact me from the button below or on the contact sheet to discuss any and all needs for your laboratories accreditation and proficiency testing requirements.  

I look forward to being your source for proficiency testing!
