Our standard of excellence works for you

"Nobody ever questions us when we submit our accreditations for a project based on procedures, proficiency sampling or lab audits. It gives us a good feeling that every time we do an audit, it will meet the minimum standards that are accepted in the Northeast."

Notice of False Claims of Accreditation

June 2, 2020
MB Professional Service, Inc. in Ontario, California and San Diego, California advertise on their website mbpro.com that their laboratory is “AASHTO accredited” and “Our certifications include AASHTO, ACI, the City of Los Angeles and more.” MB Professional Services is not AASHTO accredited and does not maintain any AASHTO certification.

If you believe a laboratory is falsely claiming AASHTO accreditation, please contact Brian Johnson (bjohnson@aashtoresource.org or 240-436-4820).

To avoid unintentionally misstating your laboratory's accreditation status, review our Policy on Publicizing Your AASHTO Accreditation.
