What Our Clients Are Saying


Newly Accredited Labs

 I believe strongly in the importance of testing for the cannabis industry and the importance for ISO 17025 accreditation. Working with Perry Johnson has been an excellent experience, as they held us to the Standard and guided us to becoming a better organization.  Their continued support has been invaluable to our business and have given us credibility in an uncertain market.
