Integrity and quality are the cornerstones of the data we provide to our clients. This understanding led us to design our quality program around strict adherence to the NELAC standards and the governing departments of the states in which we do business. We believe firmly in the value of the relationships we have with our clients; however, it is imperative that a solid quality policy create transparency in our performance. 


Accreditation & Certification


In order to maintain our NELAC accreditation and state certifications, we undergo periodic assessments and audits by the respective accrediting bodies. Each method of analysis is scrutinized to ensure complete compliance. A complete list of our accreditations and certifications can be found by visiting the Certifications page of our website.
