Certifying the organic community since 1996

Organic Certifiers is USDA-accredited and has been certifying the organic community since 1996. Our company was one of the first accredited by the USDA in early 2002.

-Our Roots- 
 The Siple Family


Organic Certifiers (OC) was established by the Siple family in Ventura County, California. Susan and Randolph Siple started OC from observing the frustrations of achieving certification. With the combination of their experience as organic farmers and private practice lawyers, Susan and Randolph knew they would make the perfect certification team. In 1996, they commenced OC and began certifying local organic farmers using a common sense approach.

-Our Accreditation- 
USDA National Organic Program

In 2002, OC was one of the first certification agencies to become accredited to the USDA NOP (National Organic Program) standard. OC began to steadily grow and gain respect in the organic community. Today, OC has grown to be California’s 3rd largest certification agency. OC continues to approach organic certification with a focus on “sound and sensible” by offering reasonable information requests, quick response time, and forming one-on-one relationships between OC representatives and clients.
