About Us

Founded in November 2003 by experienced microbiologist Elise Crowther, along with husband Martin and daughter Emily Rodgers, MVS quickly gained accreditation to ISO 9001 and ISO 13485 in February the following year.

With a growing reputation, MVS acquired the skills and knowledge of Kevin Gidney in 2005 and to date employs a further 10 employees, compromised of a Laboratory Manager, 2 Lab Technicians, 2 Environmental Technicians, 1 Lab Assistant, and Administrator and Quality Consultant. Completing the team Steve Jessop joined the company in June 2013.

With combined technical expertise of over 80 years, MVS is focused on the microbiological testing of medical and pharmaceutical products, and dedicates its time and resources entirely to providing clients with competent and rounded test house and consulting services.

Elise started her career in Microbiology in 1973 and was subsequently employed in 1984 by a major medical device manufacturer. During this time, Elise contributed to the text available in ISO 11737 relating to bioburden testing. Further knowledge was gained as part of the Gamma Panel, IDSc and ABHI meetings.

Emily has gained 10 years experience in the field through both higher education and extensive internal training.

Both Kevin & Steve previously specialised in pharmaceutical microbiology, broadening the expertise within the company and enabling MVS to test on behalf of and advise both medical device and pharmaceutical manufacturers and distributors.

Priding ourselves on the reputation gained over the past decade, MVS is dedicated to progressing with the latest technologies and guidelines, encouraging employees to seek further development, and to providing the best microbiological advice and services available in the industry to date.
